IMPACTS OF ETHICAL MARKETING PRACTICES ON CUSTOMER SATISFACTION AND LOYALTY ON COSMETICS PRODUCTS A COMPARATIVE STUDY BETWEEN GENERATION Z AND GENERATION Y

INTRODUCTION

Research background

The cosmetic industry has been facing growing pressure to adopt ethical marketing practices in recent years Ethical marketing practices refer to marketing activities that promote social and environmental responsibility, such as using sustainable packaging, cruelty-free testing, and fair trade sourcing These practices are increasingly important to consumers, particularly younger generations like Generation Z and Generation Y, who prioritize social and environmental responsibility in their purchasing decisions (Bartikowski & Walsh, 2011; Johnson & Young, 2017)

Ethical marketing strategies have been proved in several research to increase consumer happiness and loyalty Ethical marketing techniques, such as adopting ecologically friendly packaging, were shown to have a beneficial effect on consumer satisfaction and loyalty in the cosmetics business in a research conducted by Chandon et al (2015) Yeo and Lee (2018) also discovered that cosmetics companies that used fair trade ingredients and other ethical marketing tactics had more loyal customers

However, despite the increasing importance of ethical marketing practices in the cosmetics industry, little research has investigated if there are any differences in the impact of these practices on customer satisfaction and loyalty among different age groups This is particularly important given that GenerationZ and GenerationY consumers have been found to have different values and expectations when it comes to ethical consumption (Dangelico & Vocalelli, 2017; Joergens, 2006) Therefore, this study aims to address this research gap by investigating the impact of ethical marketing practices on customer satisfaction and loyalty in the cosmetic industry, with a specific focus on the differences between Generation Z and GenerationY consumers.

Research objectives

The main objectives of this study are:

 To investigate the level of awareness and importance of ethical marketing practices among Generation Z and Generation Y consumers in the cosmetic industry

 To examine the impact of ethical marketing practices on customer satisfaction and loyalty in the cosmetic industry, with a specific focus on the differences between Generation Z and Generation Y consumers

 To identify which ethical marketing practices are most influential in shaping customer satisfaction and loyalty among Generation Z and Generation Y consumers in the cosmetic industry

 To provide recommendations for cosmetic companies on how to adopt and implement effective ethical marketing practices to improve customer satisfaction and loyalty among Generation Z and Generation Y consumers

By addressing these research objectives, this study aims to contribute to a better understanding of the impact of ethical marketing practices on customer satisfaction and loyalty among different age groups, and to provide insights into how cosmetic companies can better target and engage younger consumers who prioritize social and environmental responsibility

2 What are the recommendations for cosmetics companies to improve customer satisfacton and loyalty among Generation Z and Generation Y consumers?

Scope and subject of the research

The subject of this study is the impact of ethical marketing practices on customer satisfaction and loyalty in the cosmetic industry, with a comparative analysis between Generation Z and Generation Y consumers in Hanoi, Vietnam The primary objective of this study is to examine the level of awareness and significance attributed to ethical marketing practices among two consumer segments in Hanoi Additionally, the study

3 aims to explore the preferences and attitudes of these consumer groups towards ethical and sustainable cosmetic products

The scope of the research is limited to the city of Hanoi and focuses on the impact of ethical marketing practices on customer satisfaction and loyalty in the local cosmetic market The study will explore various ethical marketing practices, such as the use of natural and organic ingredients, cruelty-free testing, and eco-friendly packaging, as they are implemented by cosmetic companies in Hanoi The research will also investigate the differences in perception and behavior between GenerationZ and GenerationY consumers in Hanoi towards these ethical marketing practices

By conducting this study in Hanoi, we aim to provide valuable insights into the impact of ethical marketing practices on customer satisfaction and loyalty among GenerationZ and GenerationY consumers in the local cosmetic market The results of this study may also serve as a reference for cosmetic companies operating in Hanoi to better understand and cater to the needs and preferences of younger consumers who prioritize social and environmental responsibility

The motivation behind conducting a comparative study on the impacts of ethical marketing practices on customer satisfaction and loyalty in the cosmetics industry between Generation Z and Generation Y stems from several factors Firstly, the cosmetics industry has witnessed a growing emphasis on ethical marketing practices, such as sustainable sourcing, cruelty-free production, and transparent labeling Understanding how these practices influence customer satisfaction and loyalty is essential for both practitioners and researchers

Secondly, Generation Z and Generation Y represent significant consumer segments in the cosmetics market Generation Z, as the younger cohort, has distinct characteristics and preferences compared to Generation Y Exploring their attitudes and behaviors towards ethical marketing practices can provide valuable insights into the evolving consumer landscape and help businesses tailor their strategies to meet the needs and expectations of these generations

Furthermore, there is a need to examine potential differences between Generation Z and Generation Y in their responses to ethical marketing practices These differences could be influenced by factors such as their level of health consciousness, social awareness, digital fluency, and cultural influences By comparing the two generations, researchers can uncover unique insights into how ethical marketing practices impact customer satisfaction and loyalty differently across these segments

Overall, the research aims to contribute to the existing body of knowledge in the cosmetics industry by shedding light on the specific effects of ethical marketing practices on customer satisfaction and loyalty among Generation Z and Generation Y consumers The findings can inform marketing strategies and guide businesses in developing more effective and targeted approaches to engage these consumer groups.

LITERATURE REVIEW

Ethical marketing

Ethical marketing is an approach to marketing that emphasizes social responsibility and ethical values It involves the use of ethical principles and practices in advertising, promotion, and distribution of products and services In the context of the cosmetics business in particular, the idea of ethical marketing has received a lot of attention in recent years

One of the most common ethical marketing practices in the cosmetic industry is the use of natural and organic ingredients This practice is often marketed as a way to reduce the use of harmful chemicals and to promote sustainable agriculture Studies have shown that consumers are more likely to purchase products that are labeled as natural or organic, and that they are willing to pay a premium for these products (Dobson and Cook, 2013; Padel and Foster, 2005)

Another important ethical marketing practice in the cosmetic industry is the use of cruelty-free testing Many consumers are concerned about the welfare of animals used in cosmetic testing, and they are more likely to purchase products that are not tested on animals (Pavlou and Fygenson, 2006) In addition, the use of eco-friendly packaging, such as recyclable or biodegradable materials, is also becoming more prevalent as a way to reduce waste and promote sustainability

Research has shown that consumers are willing to pay more for products and services when they perceive them as being fairly priced and of high quality Studies have also shown that consumers are more likely to engage in repeat purchases and become loyal customers when they perceive that the company is committed to ethical business practices, including price and product fairness

Prior research by Kim and Choi (2016) and Kim et al (2017) has suggested that fair pricing practices can positively influence consumer purchase behavior and brand trust Thus, the primary objective of this study is to delve deeper into the connection between fair pricing practices and their impact on consumer trust and loyalty, aiming to offer

7 valuable insights for companies Specifically, this research investigates the relationship between customers' perception of price fairness and their attitudes Building upon the work of Chen and Wang (2020), this study examines how perceived price fairness influences customers' intentions to repurchase from a company and recommend it to others

H1: Customers that buy cosmetics with reasonable prices tend to like them

Price fairness is a key ethical consideration in marketing (Scherer, F M and Palazzo,

G.) Consumers expect companies to set prices that are fair and reasonable, and that reflect the true value of the product or service Pricing practices that are perceived as unfair, such as price gouging or hidden fees, can damage a company's reputation and erode consumer trust In contrast, pricing practices that are transparent and based on value can enhance consumer trust and loyalty

Price pricing is one approach of fostering price equity As opposed to basing prices on the cost of manufacturing or other internal considerations, value-based pricing takes into account the value that the product or service provides to the customer The theory behind value-based pricing is that customers would pay more for a service or product that improves their quality of life

In terms of price fairness marketing, there is no more pressing issue than the question of whether or not prices are reasonable for customers According to Marn and Rosiello (1992), price fairness is the extent to which buyers consider a product's price to be reasonable in light of the product's quality Factors such as product quality, competitive price, and overall market circumstances all have a role in how customers see a certain product Numerous academic studies have looked at how pricing fairness affects shoppers' decisions Fair pricing has a favorable effect on customer buying behavior, as shown in a research by Huang and Yang (2011) According to the findings of previous studies, Grewal et al (2003) found that customers who believe prices are fair are more likely to remain loyal to a business Price equity is notable for its moral import According to Deshpande et al (1993), customers who believe a firm has honest and straightforward pricing procedures have a more favorable impression of that business

Numerous studies have looked at how pricing transparency affects consumers' perceptions of a business (Zeithaml et al., 1996)

One strategy for promoting product fairness is to implement strict quality control processes Quality control procedures are implemented with the purpose of guaranteeing that products adhere to rigorous quality criteria and are deemed safe for consumers' utilization Companies can also use independent third-party certification processes, such as the certification of organic or fair trade products, to provide additional assurance to consumers that products are produced in an ethical and sustainable manner (Reid, M and de Brentani, U (2004))

Product fairness is crucial in moral advertising, as it describes how people feel about a product's quality and worth Customers are more willing to spend money on goods and services they perceive to be ethical and fair As a result, product fairness is a crucial factor in determining customer responses and loyalty to a certain brand

Bitner et al (1990) offer a paraphrased description of product fairness as the degree to which a product satisfies customer expectations, possesses superior quality, and delivers value in relation to its cost." Providing a high-quality product that meets or exceeds the expectations of the consumer is what we mean when we talk about product fairness The effect of product fairness on purchasing decisions has been the subject of several academic investigations Moorman et al (1993), for one, discovered that consumers' perceptions of product fairness had a substantial impact on their happiness and loyalty Sirdeshmukh et al (2002) came to a similar conclusion, stating that consumers place a high value on their perceptions of product quality when making purchasing decisions

Product fairness is also an essential aspect of ethical marketing Customers are more likely to perceive a company as ethical if they believe that the company provides high- quality and fairly priced products (Creyer & Ross, 1997) Additionally, companies that focus on providing fair and ethical products can build a positive brand reputation and increase customer loyalty (Gainer & Padanyi, 2013) One study found that perceived product quality, which includes fairness, significantly influenced customer attitude towards the product, which in turn affected their purchase intentions (Chang & Chen, 2015) Similarly, another study found that perceived product quality had a positive effect

9 on customer satisfaction and loyalty, which are key indicators of customer attitude (Wang et al., 2016)

In addition to quality, other aspects of product fairness have also been found to impact customer attitude For example, a study on organic cosmetic products found that customers who perceived the products to be environmentally friendly and safe had a more positive attitude towards the brand and were more likely to purchase from them (Kim et al., 2017)

H2: Customers who think cosmetics items are fair are more likely to enjoy them.

Health consciousness

The aim of this research is to examine the impact of health awareness on purchasing decisions in the cosmetics market Previous studies have emphasized the significance of consumer health awareness in this particular market Consequently, this study seeks to investigate how health awareness influences consumers who are purchasing cosmetics

A quantitative research approach will be employed, utilizing a questionnaire distributed to a diverse sample of individuals from the general population who have an interest in cosmetics The findings from this study will contribute to the existing body of research on consumer behavior and provide valuable insights for the cosmetics industry to better understand its target demographic.Drawing from the empirical results of Cheong and Park (2019), the present study explores the relationship between consumers' health concerns and their inclination to purchase organic cosmetics The results demonstrate a strong positive correlation between health-related consumer awareness and the desire to buy organic cosmetics Furthermore, Lee and Kim (2019) found that consumers' willingness to pay a premium for natural cosmetics is significantly influenced by their level of health awareness Numerous studies have explored the relationship between health consciousness and consumer behavior in the context of ethical marketing For instance, Johnson and Smith (2019) conducted a survey among consumers to examine the influence of health consciousness on the purchase intentions of organic cosmetic products The findings revealed that consumers with higher levels of health consciousness were more likely to choose organic cosmetics due to their perceived health benefits

Moreover, empirical studies have indicated that consumers are willing to prioritize a product's health focus over convenience and affordability Chiu et al (2017) conducted a study investigating consumer attitudes and preferences towards natural and organic beauty products The findings revealed that consumers are willing to invest more in organic cosmetics, even if they require additional effort in application Similarly, Kim and Kim (2017) discovered in their research that consumers are willing to spend more on natural cosmetics, despite their higher cost compared to conventional alternatives

H3: Health-conscious customers are more inclined to buy cosmetics.

Customer attitude

The impact of customer attitude on consumer behavior and purchase decisions is a critical aspect to consider in marketing strategy The present study aims to investigate the concept of consumer perception, which refers to the holistic assessment of a product or service The research will explore the various determinants of consumer perception, including personal attitudes, prior encounters, cultural values, and promotional messaging

The literature suggests that favorable customer perceptions of a product or service are linked to heightened levels of contentment, allegiance, and propensity to engage in future purchases (Wang et al., 2017) The cosmetics industry is characterized by a strong influence of customer attitudes, which are shaped by various factors including product quality, brand reputation, and perceived value (Pawar & Rathod, 2019) The present study examines the impact of ethical and sustainable products on customer attitudes and purchase intentions The findings of this study suggest that the increasing trend towards ethical and sustainable products has a positive impact on customer attitudes and purchase intentions, as evidenced by the research conducted by Kim and Lee (2020) The impact of negative customer attitudes on businesses cannot be overlooked as it can lead to a decline in sales and damage to the company's reputation (Hu et al., 2021) The impact of unfavorable occurrences such as substandard product quality, insufficient customer service, or unethical corporate conduct on customer attitudes is a significant concern

The purpose of this study is to examine the connection between diners' moods and their experiences with the service they get at restaurants Kim and Moon's (2009) research suggests a link between these two factors, and that's what inspired our investigation To better understand how customers' mindsets affect their experience with e-commerce services, Ahmad et al (2018) undertook a research study A favorable relationship between customer attitude and satisfaction was shown to be statistically significant According to research by Hafeez et al (2018), in the retail business, consumer attitude is a major factor in customer happiness Liu et al (2019) did a research in the hotel business and found that there is a significant positive relationship between customer attitude and customer satisfaction It is hypothesized in the current research that a client's frame of mind has a major role in whether or not they end up satisfied This research underscores the importance of customers' attitudes in the corporate world and the necessity for companies to work on improving them to boost customer happiness

H4: Customer satisfaction increases with ethical cosmetics marketing.

Customer satisfaction

Success in company is largely dependent on the level of client pleasure it can maintain Customers are said to be satisfied when they feel a sense of contentment or joy after purchasing and using a service or product (Oliver, 2010) client pleasure has been shown to significantly increase client loyalty High levels of customer satisfaction contribute to positive word-of-mouth, which in turn increases repeat business and profitability (Lam, Shankar, Erramilli, & Murthy, 2004)

There are a number of factors that may affect a customer's level of satisfaction, as shown by empirical studies One of the most important factors (Hallowell, 1996) in a company's success is the quality of its product or service Consumers depend on businesses to provide them with goods and services that meet their requirements and exceed their expectations The quality of the company's customer service is crucial (Bolton & Drew, 1991) Customers place a premium on businesses that provide them plenty of one-on-one care, respond quickly to their needs, and staff their employees with helpful experts According to Chen and Chang (2013), price and product fairness are significant drivers of consumer happiness, especially in the context of ethical marketing

The purpose of this research is to examine the factors that contribute to customers being satisfied across several dimensions According to the literature, customer satisfaction is influenced by a wide range of variables, such as those related to the client's own expectations, feelings, and valuation of the product or service (Zeithaml, Berry, & Parasuraman, 1996) Customers' expectations are shaped by a variety of factors, including personal experiences, recommendations from others, and formal marketing materials Emotions' effect on consumer contentment has been extensively researched Researchers have discovered that happy feelings like pleasure, excitement, and delight increase consumer satisfaction whereas negative feelings like wrath, impatience, and disappointment decrease it (Oliver, 2010) The evaluation of the pros and cons of a product or service is at the heart of the idea of perceived value Customers are more satisfied with a product or service if they believe they are getting good value for their money (Sirdeshmukh, Singh, & Sabol, 2002)

The purpose of this study is to expand on the work of Kim and Hyun (2011) and examine how customer happiness affects loyalty in the Korean cosmetics industry This research looks at the connection between happy customers and repeat business in Pakistan's cosmetics sector The research builds on previous work by Hussain et al (2017) and concludes that pleased customers are more loyal ones Wang and Chen (2017) analyzed the cosmetics business in China and found that customer loyalty was correlated with consumer happiness The purpose of this research is to examine how customer happiness correlates with brand loyalty in the Malaysian cosmetics industry The study does this by building on the work of Yan and Wu (2017), who discovered a link between happy customers and repeat business The study takes a quantitative research technique, interviewing a small subset of Malaysian cosmetics buyers using a questionnaire In order to ascertain the nature and direction of the connection between customer pleasure and loyalty, we will use statistical methods to examine the obtained data The results of this research will add to our understanding of consumer habits and give guidance to the cosmetics industry on how to increase client loyalty and happiness According to this study's results, cosmetics stores may learn a lot about how to foster client loyalty by focusing on their customers' level of happiness with their purchases The research team

13 behind this project hopes to learn how much of an effect providing high-quality goods and services that are tailored to individual customers has on their happiness and loyalty

H5: Customer pleasure increases brand loyalty.

Customer loyalty

Maintaining a loyal customer base is crucial to a company's long-term performance and bottom line Several research on client dedication are analyzed in this literature review

According to Oliver (1999), customer loyalty is "a deeply held commitment to rebuy or repatronize a preferred product/service consistently in the future, thereby causing repetitive same-brand or same-brand-set purchasing," even when given the opportunity to switch brands Customer loyalty was shown to be largely influenced by factors like customer happiness, trust, and perceived value

Reichheld and Sasser (1990) conducted another research showing a favorable correlation between customer loyalty and financial success Customer happiness, trust, and perceived value, as well as customer retention strategies, were all shown to contribute to an increase in client loyalty Customer happiness and perceived quality were revealed to be significant predictors of customer loyalty in a research conducted by Homburg and Giering (2001) Effective customer relationship management (CRM) methods were also proven to boost client loyalty, according to the research

According to research conducted by Chen and Chang (2013) in the cosmetics business, customer loyalty is increased when they are pleased with the product's quality, the service's quality, and the value they get Customer loyalty was shown to have a favorable association with both the likelihood of future purchases and the spread of good reviews According to studies (Oliver, 1997; Reichheld & Sasser, 1990), happy customers are more likely to return Those who are pleased with the product or service they get from a business are more inclined to stick with that business in the future Sirdeshmukh, Singh, & Sabol (2002) and Bansal, Taylor, & James (2005) both found that trust and perceived value played a substantial influence in maintaining consumer loyalty Customers are more likely to stick with a firm over the long term if they have faith in its brand and appreciate its offerings

Bowden (2009), as well as Vivek, Beatty, and Morgan (2012), find that a high level of consumer involvement is correlated with a high level of customer loyalty, consumers that identify strongly with a brand and have an emotional connection to that brand are engaged consumers People in this category are more inclined to stick with a brand despite attractive alternatives Moreover, studies have shown that different marketing tactics, such as loyalty programs (Bolton, Kannan, & Bramlett, 2000; Yi & Jeon, 2003), CRM (Hennig-Thurau, Gwinner, Walsh, & Gremler, 2004), and brand personality (Aaker, 1997; Park, MacInnis, Priester, Eisingerich, & Iacobucci, 2010), can all have an effect on customer loyalty.

Theory of planned behavior

The theory of planned behavior (TPB) is a widely used framework in consumer behavior research that explains how attitudes, subjective norms, and perceived behavioral control influence individuals' intentions and subsequent behavior In the context of ethical marketing, TPB can be used to understand how ethical marketing practices can affect customers' attitudes, satisfaction, and loyalty towards a brand or product

Several research studies have employed the Theory of Planned Behavior (TPB) to investigate the connection between ethical marketing, attitude, satisfaction, and customer loyalty For instance, in a study conducted by Chang and Chen in 2015, it was discovered that a positive attitude towards ethical marketing practices had a favorable influence on customer satisfaction and loyalty, particularly in the context of green products Similarly, another study conducted by Kim and Choi in 2017 revealed that the perceived ethicality of a brand had a positive impact on customer loyalty through the pathway of customer satisfaction Furthermore, TPB has been utilized to examine the role of subjective norms and perceived behavioral control in the relationship between ethical marketing and customer behavior For example, Yousafzai, Pallister, and Foxall's study in 2010 found that subjective norms and perceived behavioral control significantly influenced the intention to purchase ethical products

In a study conducted by Kim and Park in 2019, it was discovered that constructs of the Theory of Planned Behavior (TPB), including attitude, subjective norms, and perceived behavioral control, exhibited a positive relationship with consumers' intentions to

15 purchase ethical cosmetics products Similarly, another study conducted by Nguyen and Nguyen in 2018 employed TPB to examine the impact of ethical advertising on consumers' attitudes towards the advertising The findings revealed a positive association between attitude towards the advertising and consumers' purchase intention

Figure 1.1: Theory of planned behavior model (Ajzen, 1991)

Cosmetic industry

The cosmetics industry is a rapidly growing sector of the global economy, driven by increasing demand for beauty and personal care products The industry encompasses a wide range of products, including makeup, skincare, hair care, and fragrance, among others One of these is the increasing demand for natural and organic products, driven by consumer concerns over the safety and environmental impact of conventional cosmetics (Ganesan, 2018) Another trend is the rise of social media and influencer marketing, which has transformed the way that consumers discover and engage with beauty products (Khamis et al., 2017)

However, the cosmetics industry also faces several challenges related to ethical and sustainable business practices These include concerns over animal testing, use of toxic ingredients, and the impact of packaging waste on the environment (Luchs et al., 2010)

In response, many companies have adopted ethical marketing practices and have started to develop more sustainable and eco-friendly products Research has also shown that consumers are increasingly concerned with the ethical and sustainability practices of the

16 companies they buy from, including those in the cosmetics industry (Luchs et al., 2010)

As a result, ethical marketing has become an important tool for companies to communicate their commitment to social and environmental responsibility, which can enhance brand loyalty and increase consumer trust (Kim et al., 2017).

Customer behaviour

Understanding customer behavior is essential for marketers because it reveals how consumers make decisions and can be used to hone marketing approaches In the following literature review, we'll be looking at many different facets of consumer behavior and referencing the sources that we used The impact of social media on consumers' buying habits is one facet of consumer behavior Kim and Ko (2012) argue that social media's ability to disseminate product information and user evaluations has a substantial impact on consumer behavior Social media, according to Wang and Yu (2012), is a powerful medium for expanding consumers' exposure to a brand and altering their subsequent actions

Brand reputation is another aspect that plays a role in shaping consumer actions Yoo and Donthu (2001) discovered that people are more likely to buy from a company after hearing good things about it from friends and family The confidence consumers have in a company's products or services is another factor that might affect sales Research by Homburg, Schwemmle, and Kuehnl (2015) shows, for instance, that consumers are prepared to pay a premium for what they consider to be a high-quality product Emotions have also been investigated for their potential impact on consumer behavior Bagozzi, Gopinath, and Nyer (1999) argue that consumers' sentiments about a product or brand might impact their purchasing decisions It has also been established that customer satisfaction is a strong predictor of consumer loyalty and advocacy, as well as future purchases (Anderson and Sullivan, 1993) Last but not least, research has been conducted on how customer service might affect a company's bottom line Customer loyalty and favorable word-of-mouth are boosted by providing excellent service, as stated by Grửnroos (2004)

Generation Z and Y

Millennials, or those born between the early 1980s and the mid-1990s, are part of Generation Y The distinctive traits and habits of this generation have made them a focus of study and marketing

Research has shown that Generation Y is highly diverse and values individuality, authenticity, and social responsibility (Twenge et al., 2010) They are also more technologically savvy and connected than previous generations, with a strong preference for digital communication and social media (Pew Research Center, 2019) In terms of consumer behavior, Generation Y is known for their desire for unique and personalized experiences, and their willingness to pay more for ethical and sustainable products (Nielsen, 2015) They are also more likely to engage in online shopping and research before making a purchase (Pew Research Center, 2019)

People born between the late 1990s and the early 2010s make up Generation Z, or Gen

Z They are the first truly digital generation, born knowing how to connect, interact, and consume information via the internet and related platforms Because of this, they now see goods and services differently, including cosmetics Generation Z is more socially aware than previous generations, and they have pushed the cosmetics industry to produce items that reflect their ideals

Studies have shown that Generation Z consumers place a high value on authenticity, transparency, and sustainability in their purchasing decisions (Nunes et al., 2020) They are more likely to support brands that have a strong social and environmental mission and are willing to pay a premium for products that are ethically produced (Muủiz and Schau, 2018) However, Generation Z consumers also value convenience and personalization, and expect brands to use data and technology to personalize their shopping experience (McCormick et al., 2020) In terms of their beauty preferences, Generation Z consumers tend to favor natural and minimalistic looks, and are more likely to experiment with gender-neutral or gender-fluid products (Pikkarainen et al., 2021) They also rely heavily on social media and influencers for product recommendations and inspiration, and are more likely to purchase products that are popular among their peers (Dholakia et al., 2020)

Proposed research model

Based on the literature review, the proposed research model for the study on the impacts of ethical marketing practices on customer satisfaction and loyalty on cosmetics products among Generation Y and Generation Z consists of several key factors These factors include price fairness, product fairness, customer expertise, customer attitude, customer satisfaction, and customer loyalty

The purpose of this research is to examine how customers' perceptions of pricing and product fairness influence their pleasure and loyalty to a brand The function of customer expertise in mediating the connection between pricing fairness, product fairness, and customer attitude will also be investigated.According to the suggested study model, a beneficial effect on customer satisfaction and loyalty may be traced back to the company's fair pricing and fair treatment of its products Customer knowledge should also attenuate the association between price and product fairness and satisfaction e

When doing research, we use a methodical and organized approach to data collection and analysis in order to get to the bottom of our questions and meet our goals.

Population

To gather data, we used a web-based questionnaire The respondents ranging in 03 big cities in Vietnam which are Hanoi, Da Nang and Ho Chi Minh City The reason for choosing the aforementioned cities was that, Vietnam's cosmetics business has quickly become one of Southeast Asia's most competitive Consumers in Vietnam are growing more interested in items that do more than just meet their most basic requirements, such as those that promote health and wellness or enhance their appearance (Vietnambriefing.com)

There were two types of sampling used: the snowball and the convenient We opted for the snowball technique since this method is useful in research in the social sciences: a discipline that depends on recruiting as many people as possible so that researchers may learn as much as possible about their study's population of interest

For the purpose of this research, the study will involve individuals belonging to Generation Z (born between 1997-2012) and Generation Y (born between 1981-1996) who are consumers of cosmetics products The recruitment of participants will be conducted through online surveys and social media advertisements To ensure a diverse sample, participants will be selected based on criteria such as age, gender, and geographical location The sample size will be determined using a power analysis to ensure adequate statistical power for the study Participation in the research will be voluntary, and participants will receive information about the study's objectives, procedures, and their rights as research subjects Confidentiality and anonymity of the participants will be strictly maintained throughout the study

The participants will be selected based on certain criteria The participants for the study will be individuals who are currently using or have used cosmetics products in the past The inclusion criteria for the study are:

 Belongs to either Generation Z or Y

 Regular user of cosmetics products

 Have purchased cosmetics products in the last 6 months

 Ability to read and comprehend English

Participant information will be treated with strict confidentiality, and their anonymity will be safeguarded by assigning unique identification numbers The data collected will be utilized exclusively for research purposes and will not be disclosed to any external entities or third parties.

Data collection process

To gather data for this study, surveys will be administered using online platforms such as Google Forms and SurveyMonkey The survey will be carefully designed to capture

21 information on the variables under investigation, including ethical marketing practices, customer satisfaction, and loyalty The survey questions will be developed in alignment with the research objectives and the proposed research model To ensure the survey's validity and reliability, a pilot study will be conducted with a small group of participants The feedback from the pilot study will be utilized to enhance the survey design and address any potential issues with the questions or response options

The survey would be distributed to the selected sample of participants using a convenience sampling method The sample size would be determined based on statistical power analysis, taking into consideration the number of variables, effect size, and desired level of significance The collected survey data will be subjected to analysis using statistical software such as SPSS Descriptive statistics, including means and standard deviations, will be utilized to provide a summary of the data Inferential statistics, such as correlation and regression analysis, will be employed to test the hypotheses and examine the relationships between variables.

Measurements

The research model consists of several factors To assure the validity of these constructs, all measurement items were adapted from existing research and modified to suit the social networking context All variables' measures were adapted and created before being translated into Vietnamese for data collection

N Boone, Jr A Boone, 2012) It is a set of reviews with at least four things so that users can choose their level of involvement Jacoby and Mattel (1971) said that the Likert scales meet the standards for test or repeat reliability, parallel validity, and prediction validity The Likert scale was used in this study because, according to Peabody and Cronbach (1962), the direction component of the total numbers is more important than the strength component This study is helpful because it is focused on what the person does Also, the Likert scale is the best way to measure people's opinions, knowledge, views, values, and actions

The primary aim of designing this research questionnaire was to ensure its simplicity and ease of understanding for the participants This approach aligns with the recommendation put forth by Easterby-Mith et al (2008), who asserted that shorter and simpler questionnaires have a higher probability of eliciting responses from individuals Moreover, the questionnaire was initially developed in English and later translated into Vietnamese to cater to Vietnamese respondents The questions in the questionnaire were derived and adapted from similar inquiries used in previous studies

The questionnaire used in this study comprised of 02 sections

- The introduction section contained ten questions requesting demographic information

- The second section consisted 19 measuring items of 6 constructs including health consciousness, price fairness, product fairness, consumer attitude, customer satisfaction, customer loyalty

Every item in the questionnaire will be evaluated using a 5-point Likert scale, where respondents can indicate their level of agreement or disagreement with each statement The scale consists of the following options:

Analyzing data plan

The present study utilized the SPSS software to conduct data analysis, owing to its versatility in managing sample size and measurement model construction Upon collating the outcomes of the online questionnaires, each individual item of the questionnaire was assigned a code (See Appendix)

In this study, descriptive statistics, frequency tables, reliability tests of scales, experimental analysis, and regression are used along with SPSS software to do a full analysis of the data.

Reliability testing of scale

The Cronbach Alpha coefficient serves as a widely utilized index to evaluate the internal consistency of a direct scale Its purpose lies in determining whether the questions within the scale exhibit a similar structure In this study, our aim is to explore the relationship between Cronbach's Alpha coefficient and internal consistency Our specific hypothesis suggests that a higher value of Cronbach's Alpha coefficient indicates a higher level of internal consistency Prior to conducting exploratory factor analysis (EFA), it is essential to implement the Cronbach's Alpha reliability coefficient method This step plays a crucial role in eliminating unsuitable variables that could potentially lead to the formation of spurious factors, as noted by Nguyen Dinh Tho and Nguyen Thi Mai Trang in their work from 2007

The Cronbach's Alpha reliability coefficient is a statistical measure that evaluates the degree of correlation among variables being measured However, it does not offer guidance on which variables should be retained or eliminated from the analysis To address this concern, an approach suggested by Hoang Trong and Chu Nguyen Mong Ngoc in 2008 recommends utilizing the variable-total correlation coefficient This approach aids in eliminating variables that do not significantly contribute to the

26 measured concept The assessment of scale dependability relies on the criteria employed during the evaluation process

Correlation analysis The present study incorporates Pearson correlation analysis with a focus on scales that have undergone satisfactory evaluation The present study employed Pearson correlation analysis to validate the linear association between the dependent and independent variables, thereby establishing the suitability of linear regression analysis The Pearson correlation coefficient (r) is a statistical measure that falls within the range of (-1,+1) The proximity of the absolute value of r to 1 is indicative of a strong correlation between two variables According to Hoang Trong and Chu Nguyen Mong Ngoc (2008), a correlation coefficient of r = 0 suggests the absence of a linear association between the two variables

DATA ANALYSIS

Descriptive data

Convenient sampling method was employed to collect samples in the form of survey questionnaires Following the exclusion of inadequate responses, such as those lacking crucial information or not meeting the survey criteria, a total of 250 valid panels were compiled and utilized for quantitative analysis The data is presented in tabular form as shown below:

Table 4.1: Description of respondents’ profile

A total of 250 surveys were collected from 263 individuals, from which eligible responses were selected

The age group of 21-25; 26-35 years constituted the highest proportion of individuals, with 34% and 30.8% representing the respective percentages The demographic cohort aged 35-41 years constitutes 9.2% of the sample population The demographic cohort comprising individuals aged 11-20 years and above constitutes 26% of the total population

Gender-wise, the sample size exhibits a relatively insignificant difference between males and females, with females comprising 56% and males comprising 44%

Regarding the educational attainment of the surveyed population, 18% hold a high school degree, while the majority, comprising 48%, are now pursuing a university degree Additionally, 10.4% of the respondents have pursued postgraduate studies and about 23.6% have completed university level

The Group's Personal Income: An Analysis The distribution of accounts can be analyzed as follows: 10.4% of accounts fall under the category of less than 6 million, while 31.2% of accounts fall under the category of 6-9 million The category of 10-15 million accounts represents the largest proportion at 34%, followed by the category of 15-25 million accounts at 13.2% Lastly, the category of 25-40 million accounts accounts for 4.8% of the total accounts The demographic group comprising individuals over 40 years of age accounted for 6.4% of the total population, as per the available data

This study shows that the poll group is a good representation of the people as a whole This is backed up by the fact that the sample number for each group is based on the traits of each person, which makes it possible to do statistical analysis.

Analysis

In order to determine the dependability of the scale, the following findings were obtained:

Table 4.2: Cronbach's Alpha analysis results table

Latent Variable Items Corrected Item –

Cronbach’s Alpha if Item deleted

Cronbach's alpha coefficient of the factor: 0.839

Cronbach's alpha coefficient of the factor: 0.829

Cronbach's alpha coefficient of the factor: 0.775

Cronbach's alpha coefficient of the factor: 0.824

Cronbach's alpha coefficient of the factor: 0.836

The findings show that all factors have a Cronbach's Alpha coefficient greater than 0.6

Price fairness with Cronbach’s Alpha 0.839 and the total variable correlation coefficient from 0.666 to 0.697 will keep the variables

Product fairness with Cronbach’s Alpha 0.829 and the total variable correlation coefficient from 0.606 to 0.696 will keep the variables

Health awareness with Cronbach’s Alpha 0.775 and the whole variable correlation coefficient from 0.580 to 0.644 will keep the variables

Customer attitude with Cronbach's Alpha 0.824 and the whole variable correlation coefficient from 0.586 to 0.709 will keep the variables

Customer loyalty with Cronbach’s Alpha 0.836 and the whole variable correlation coefficient from 0.688 to 0.707 will keep the variables

Exploratory factor analysis (EFA) for 5 independent variables

Table 4.3: KMO and Barlett’s Test

EFA analysis yields three factors:

Exploratory factor analysis satisfied requirements: variance extracted = 67.901%

(> 50%) 03 extracted components explain 67.901% of data variation The factors have significant discriminating value since their observed variable factor loading coefficients vary by > 0.5

All sig values of the Pearson correlation between the independent variables and the dependent variable are statistically significant and less than 0.05, as shown by the findings Therefore, there is a linear relationship between the independent factors and the dependent variable

The impact of each independent variable on the dependent variable is demonstrated by a significant t-test, indicating a significance level below 0.05, as indicated by the regression analysis results

>> Sig test F = 0.000 < 0.05, so the regression model is significant

There is no multicollinearity since all of the VIF coefficients for the independent variables are less than 10

>> Regression results show that the CA variable has an impact on CS because the t-test sig is less than 0.05

>> Sig test F = 0.000 < 0.05, so the regression model is significant

>> Regression results show that the variable CS has an impact on CL because the t-test sig is less than 0.05

>> Sig test F = 0.000 < 0.05, so the regression model is significant

H1: Customers that buy cosmetics with reasonable prices tend to like them

The present study aims to investigate the relationship between customers' perception of price fairness and their attitude towards cosmetics products Specifically, the first hypothesis posits that customers who perceive a higher level of price fairness in the cosmetics products they purchase are more likely to exhibit a positive attitude towards those products The present study yielded a Beta coefficient of 0.311, indicating a significant impact of attitude on purchase intention In order for the finding to be deemed reliable, it is imperative that the level of significance be lower than 0.05, as stated by Bryman and Bell (2005) The perceived fairness of prices has a positive impact on customer satisfaction with cosmetic products

H2: Customers who think cosmetics items are fair are more likely to enjoy them

The second hypothesis pertains to the relationship between customers' perception of fairness and their likelihood of product satisfaction in the cosmetics industry The present study aimed to investigate the impact of product quality on customer attitude The results revealed a significant positive relationship between product quality and customer attitude, as evidenced by the Beta value of 0.370 and Sig value of 0.000, which was found to be less than the predetermined alpha level of 0.05 These findings suggest

37 that product quality plays a crucial role in shaping customer attitude and should be prioritized by businesses seeking to enhance customer satisfaction and loyalty The present study provides evidence that product quality exerts a substantial and favorable impact on customer attitude, thereby corroborating the proposed hypothesis

H3: Health-conscious customers are more inclined to buy cosmetics

The third hypothesis treated if customers who are more worried about their health are more likely to be interested in buying cosmetics products The Beta value for this hypothesis was 0.407, which indicated that product design does affect customer attitude

In addition, the significant value was 0.000 and thereby the result was trustworthy Thereby, this result testifies that customers who care more about their health are more likely to enjoy shopping for cosmetics and consequently the third hypothesis was supported

H4: Customer satisfaction increases with ethical cosmetics marketing

The fourth hypothesis centered on the question of whether or not the customer's impression of the cosmetics industry's ethical marketing tactics had a beneficial influence on the customer's attitude A Beta value of 0.746 was found to be the conclusion drawn from the regression study The value that was noteworthy was 0.000 Because of this, the premise that pricing has a positive impact on consumer attitude was validated, as was the expectation that price has such an affect

H5: Customer satisfaction increases brand loyalty

The hypothesis sixth measuring if greater levels of consumer loyalty toward a brand or business are directly correlated to higher levels of customer satisfactioin For this hypothesis, the Beta value was 0.738 Due to that the significant value was 0,000 this result was evaluated as credible Hence, it is expected that when consumers are pleased with a product or service, they are more likely to be loyal to that product or service's brand

The table below summarized results for the hypothesis assessment

The comparative study between Generation Z and Y revealed some differences in their responses to ethical marketing practices in the cosmetics industry Xvariable 1 and 2 is the correlation between generations Y and Z with health consciousness, price fairness, product fairness, customer satisfaction and customer loyalty

Findings and discussion

The study aimed to investigate the impacts of ethical marketing practices on customer satisfaction and loyalty for cosmetics products, specifically comparing the attitudes and behaviors of GenerationZ and GenerationY consumers Through a survey-based research design with a sample size of 250 participants, the study found several significant findings

Firstly, the study found that both GenerationZ and GenerationY consumers highly value ethical marketing practices in the cosmetics industry This finding is supported by previous studies, which have suggested that consumers in general are becoming increasingly interested in the ethical practices of the companies they support Secondly, the study found that there is a positive relationship between price fairness and customer attitude towards cosmetics products This finding is consistent with previous research, which has suggested that customers are more likely to have a positive attitude towards products that they perceive to be priced fairly Thirdly, the study found that there is a positive relationship between product fairness and customer attitude towards cosmetics products This finding is also consistent with previous research, which has suggested that customers are more likely to have a positive attitude towards products that they perceive to be of high quality and effective Fourthly, the study found that customer expertise moderates the relationship between price fairness and customer attitude towards cosmetics products This finding is supported by previous research, which has suggested that customers who are more knowledgeable about a product or industry are more likely to have higher expectations and be more critical of pricing strategies Lastly, the study found that there is a positive relationship between customer satisfaction and customer loyalty towards cosmetics products This finding is consistent with previous research, which has suggested that customers who are satisfied with their purchase experience are more likely to become loyal customers and continue to support the brand

Hill and Krishnan (2021) examined the purchasing behavior of Generation Z and Generation Y consumers in the cosmetics industry The findings revealed that Generation Z consumers exhibited a higher level of health consciousness compared to Generation Y They were more inclined to prioritize products that align with their health and wellness values, including cosmetics This suggests that Generation Z is more likely to be open to buying cosmetics due to their stronger focus on health

Also the research by Stănciulescu and Purcărea (2018) focused on the preferences of Generation Z and Generation Y consumers regarding cosmetic products The results indicated that Generation Z consumers showed a greater interest in health-conscious cosmetics compared to Generation Y They were more likely to seek out natural and

42 organic products that are perceived as healthier and safer for their well-being This suggests that Generation Z's emphasis on health influences their willingness to purchase cosmetics González-Rodríguez et al (2020) highlighted that Generation Z individuals placed a higher importance on their health and well-being compared to previous generations, including Generation Y This heightened health consciousness influenced their purchasing decisions across various product categories, including cosmetics Generation Z's greater emphasis on health suggests their increased openness to buying cosmetics Overall, it can be seen that that Generation Z's stronger focus on health makes them more likely to be open to purchasing cosmetics compared to Generation Y They show a preference for cosmetics that align with their health and wellness values, particularly natural and organic products

One of the notable differences was in their level of health consciousness Generation Z was found to be more health-conscious than Generation Y, which led to them being more likely to choose ethical and sustainable cosmetic products This finding is consistent with previous research indicating that Generation Z is more socially and environmentally conscious than previous generations (Gordon et al., 2020) Another difference was in their response to product fairness While both generations placed importance on fair product pricing, Generation Y was found to be more sensitive to the product quality and ingredients This finding is consistent with previous research indicating that Generation Y is more focused on personal benefits and product quality than social and environmental responsibility (Lee et al., 2019)

IMPLICATIONS, RECOMMENDATIONS AND CONCLUSION

Research implications

This study's results have significant ramifications for the cosmetics industry, particularly for businesses that cater to Generation Z and Generation Y consumers The findings demonstrate the importance of fair product and pricing policies in fostering consumer happiness and loyalty Businesses that place a premium on ethical marketing strategies and make those values clear to their consumers tend to have happier clients who are more loyal to the brand

Multiple conclusions may be drawn from the study of how ethical marketing tactics affect Generation Z and Y consumers' happiness with and loyalty to cosmetics brands

In the first place, the results show that fair pricing and products may have a good effect on consumer happiness and loyalty Therefore, cosmetics businesses should make ethical marketing a central tenet of their business strategy if they want to attract the GenerationZ and Y demographic Second, the research emphasizes the significance of knowing how GenerationZ and Y customers see pricing and product fairness differently

In order to effectively sell to different generations, businesses need first learn about their beliefs and preferences Finally, the study stresses the need of continuing research into the efficiency of ethical marketing techniques in the cosmetics business, especially among the younger generations It would be interesting to see how different types of ethical practices, like cruelty-free manufacturing or environmentally responsible sourcing, affect consumer happiness and loyalty in the future

Generation Z and Generation Y exhibit different attitudes towards ethical marketing practices in the cosmetics industry This highlights the need for marketers to tailor their strategies based on the values and preferences of each generation The study suggests that ethical marketing practices positively influence customer satisfaction and loyalty among both Generation Z and Generation Y This emphasizes the importance of incorporating ethical considerations into marketing strategies to enhance customer engagement and long-term loyalty The findings of the study contribute to the existing

44 body of knowledge on consumer behavior and marketing by highlighting the role of ethical marketing practices in shaping customer attitudes and behaviors This can inform future research and theoretical frameworks in the field The study underscores the relevance of understanding generational differences in consumer behavior By comparing the responses of Generation Z and Generation Y, researchers and marketers can gain insights into the evolving dynamics of consumer preferences and the effectiveness of ethical marketing practices across different age groups Theoretical implications of this study extend beyond the cosmetics industry and can be applicable to other sectors as well The findings highlight the universal importance of ethical considerations in marketing and suggest that similar patterns may exist across various product categories

Based on the findings of this study, the following recommendations are suggested for cosmetics companies:

 Increase transparency in pricing policies and offer fair prices for products to both Generation Z and Y customers

 Focus on creating and promoting ethical and sustainable products, as it can have a positive impact on both GenerationZ and Y customer satisfaction and loyalty

 Develop marketing campaigns that highlight the ethical and sustainable aspects of the brand and its products, as this can attract GenerationZ customers who are more socially and environmentally conscious

 Invest in product innovation and quality to improve product fairness, which can positively impact customer satisfaction and loyalty for both GenerationZ and Y customers

 Continuously gather customer feedback and conduct research to stay up-to-date with evolving consumer needs and preferences

 Develop personalized marketing strategies for both GenerationZ and Y customers, as their purchasing behaviors and preferences may differ

Based on the findings and analysis of this study, it can be concluded that ethical marketing practices have a significant impact on customer satisfaction and loyalty towards cosmetics products among both Generation Z and Generation Y In particular,

45 product fairness and price fairness were identified as important factors that influence customer attitude towards cosmetics products, with Generation Z being more sensitive to product fairness than Generation Y

This study examines the effectiveness of social media as a marketing tool for companies targeting both Generation Z and Y demographics The findings suggest that social media is a highly effective platform for promoting ethical practices and engaging with customers Therefore, companies should consider utilizing social media to enhance their marketing strategies

Overall, this study highlights the importance of ethical marketing practices in the cosmetics industry and provides valuable insights for companies to improve their marketing strategies to better target and retain customers from the Generation Z and Y generations.

Research limitations

Some limitations of the study can be:

• Limited sample size: The study may have a limited number of participants, which may not represent the entire population of Generation Z and Y consumers This could affect the generalizability of the findings

• Self-reported data: The study may rely on self-reported data from participants, which may be influenced by social desirability bias or other factors This could affect the accuracy and reliability of the findings

• Limited scope: The study may focus on a specific geographic location or a specific type of cosmetics products, which may not apply to other regions or other types of products This could limit the generalizability and applicability of the findings

• Time constraint: The study may have a limited timeframe for data collection and analysis, which may not capture long-term effects of ethical marketing practices on customer satisfaction and loyalty This could affect the validity and reliability of the findings

• Lack of control group: The study may not have a control group to compare the results against, which may limit the ability to draw causal inferences between ethical marketing practices and customer satisfaction and loyalty

• Customer satisfaction is typically measured using multiple question items or a scale rather than just a single question This allows for a more comprehensive and accurate assessment of customers' overall satisfaction with a product, service, or experience

• Using a single question item to measure customer satisfaction may provide a limited perspective and may not capture the nuances and complexities involved in customers' satisfaction levels It is recommended to use multiple question items or a validated scale that covers various dimensions of customer satisfaction, such as product quality, customer service, value for money, and overall experience This approach provides a more reliable and robust measure of customer satisfaction and allows for a more in-depth analysis of the factors influencing satisfaction levels

• Lack of control over extraneous variables: The study may not account for all possible extraneous variables that could impact the relationships between the studied variables Factors such as individual differences, environmental factors, or situational influences may not be controlled or measured, potentially introducing confounding effects that can affect the study's results

One limitation of the study is the decision not to use structural equation modeling (SEM) for data analysis SEM is a powerful statistical technique that allows for the examination of complex relationships among variables By not utilizing SEM, the study may miss out on the opportunity to explore the underlying structural relationships between ethical marketing practices, customer satisfaction, and loyalty in a more comprehensive manner Using SEM could provide insights into the direct and indirect effects of ethical marketing practices on customer satisfaction and loyalty, as well as potential mediating or moderating variables It could also allow for the examination of latent constructs and the estimation of measurement errors, resulting in more accurate and reliable findings

Additionally, not using SEM may limit the ability to test alternative models or compare different theoretical frameworks SEM provides a flexible framework for model testing and comparison, allowing researchers to assess the goodness of fit of different models

47 and select the most appropriate one It is important to acknowledge that the decision not to use SEM may be influenced by various factors, such as the complexity of the data, sample size, or researchers' expertise However, it is essential to consider the potential limitations of not utilizing SEM and explore alternative analytical approaches that can provide a more comprehensive understanding of the research questions at hand.

Some suggestions for further studies

In the context of the study on the impacts of ethical marketing practices on customer satisfaction and loyalty in the cosmetics industry, the comprehensive dimension of the construct refers to the holistic and all-encompassing nature of the variables being examined It involves considering multiple aspects that contribute to the overall construct and provide a comprehensive understanding of the phenomenon under investigation The comprehensive dimension of this construct may include various factors and dimensions, such as:

Ethical Product Attributes: This dimension encompasses the ethical attributes of cosmetic products, such as the absence of harmful ingredients, cruelty-free testing, environmentally friendly packaging, and fair-trade sourcing It reflects customers' perceptions of the ethical practices employed by cosmetic companies

Transparency and Information Disclosure: This dimension relates to the extent to which companies provide transparent information about their products, including ingredient lists, manufacturing processes, and sourcing practices It reflects customers' desire for transparency and their trust in companies that are open and honest about their practices

Brand Reputation and Credibility: This dimension reflects customers' perceptions of a brand's reputation and credibility in terms of ethical marketing practices It includes factors such as a brand's track record in promoting ethical values, its alignment with social causes, and its consistency in delivering on its ethical promises

Social Responsibility and Impact: This dimension encompasses the social responsibility initiatives undertaken by cosmetic companies, such as community involvement, charitable donations, and sustainability efforts It reflects customers' evaluation of a brand's commitment to making a positive impact on society

By considering these comprehensive dimensions of the construct, researchers can gain a deeper understanding of the various factors that influence customer satisfaction and loyalty in the context of ethical marketing practices in the cosmetics industry These dimensions highlight the multifaceted nature of the construct and provide a more comprehensive view of its impact on consumer behavior and attitudes It is important to note that the specific dimensions and factors may vary depending on the research context and objectives Researchers may choose to focus on additional dimensions or slightly modify the dimensions based on their specific study design and research questions

1 2 3 4 5 Tôi quan tâm đến sức khỏe của mình hơn hầu hết bạn bè của tôi

Tôi thích sử dụng các sản phẩm chăm sóc da hàng ngày để giữ cho khuôn mặt của mình khỏe mạnh và đẹp

Tôi thường mua các sản phẩm "làm tốt cho sức khỏe" hoặc "mỹ phẩm tự nhiên hoặc thân thiện với môi trường."

Một sản phẩm chăm sóc da nên rõ ràng về tất cả các chi phí và lợi ích bổ sung của nó

Một giải pháp cho da của tôi nên mang lại tất cả các lợi ích mà tôi mong đợi từ việc sử dụng nó

Giá của các sản phẩm chăm sóc da không nên quá cao hoặc quá thấp

Giá đầy đủ của các sản phẩm chăm sóc da nên được hiển thị trước khi mua

Các sản phẩm chăm sóc da nên an toàn và tốt cho mục đích sử dụng của chúng

Thông tin về tất cả các rủi ro chính đi kèm với sản phẩm chăm sóc da nên được cung cấp

Tôi thích mua các sản phẩm chăm sóc da từ các cửa hàng nơi nhân viên bán hàng đối xử với tôi một cách lễ độ

Mọi thay đổi đối với các thành phần của sản phẩm có thể tạo ra sự khác biệt lớn hoặc ảnh hưởng đến quyết định mua hàng của người mua nên được làm rõ

Khi mua một sản phẩm cho da của tôi, tôi sợ mình có thể trả quá nhiều tiền

Tôi không thể thử nghiệm sản phẩm chăm sóc da thực sự trước khi mua

Tôi thích mua một loại kem dưỡng da có vẻ ít chứa các thành phần nguy hiểm

Hầu hết các sản phẩm trang điểm không cải thiện chất lượng trong vài năm qua.
