Acetyl hexapeptide-8 (AH-8) is a well-known component of anti-aging products. AH-8 appears in a variety of cosmetic products, its skin penetration is sparsely studied and controversially discussed. This study investigated ampoule containing AH-8 as an active ingredient. The elasticity improving effect of 3% AH-8 ampoule was tested in vivo. To test the stability of the formulated ampoules, we performed the centrifugation, cycling and measured viscosity, and pH changes. 6 weeks-old female C3H mice were purchased from Orient Bio, Korea Inc. (Seongnam, Korea). After one week of acclimatization, the mice were randomly assigned to experimental groups (n=4 for each group); Control, UVB irradiation, Vehicle ampoule, and 3% AH-8 ampoule group. Irradiated with UVB to mouse skin, then 3% AH-8 ampoule were applied into irradiated sites for 6 weeks. Changes in the amount of TGF-β1 and collagen were measured using western blot. As a result, it was confirmed that the 3% AH-8 ampoule increased the expression of TGF-β1 and collagen. In summary, we showed that AH-8 ampoule had extremely high capability of improving elasticity when compared to vehicle ampoule containing ginkgo leaf and green tea extracts. This study revealed the efficacy of AH-8 for increasing skin elasticity and anti-aging in terms of a cosmetic active ingredient.

This study aims to investigate the relationship between psychological empowerment, positive psychological capital, and intrinsic job satisfaction of beauty workers. There are several reasons to explain that. First, as the service industry develops, the beauty industry must grow as well. Second reason is that consumers in modern society value individuality and originality. Therefore, it is important to change according to the trend of the times because the beauty industry will be eliminated if it does not keep up with the latest trend. Nevertheless, compare to other industries, the beauty industry often neglected the treatment of beauty workers and the working environment so the frequency of turnover was high. Since this could negatively affect the development of the beauty industry, it would be wise to improve or change the working environment. Accordingly, the relationship between psychological empowerment, positive psychological capital, and intrinsic job satisfaction of beauty workers was analyzed. The study subjects used analysis data of 255 beauty workers, and frequency analysis was conducted to find out the general characteristics of the survey subjects. As a result, women showed the highest gender, and those in their 20s or older showed the highest age, and in the case of education, college enrollment/graduation was the highest. The number of working years was the highest for less than one year, and in the case of beauty experience, the highest was more than five years. The salary level was the highest from 1 million won to less than 2 million won. Psychological empowerment, positive psychological capital, and intrinsic job satisfaction were all positively related. Therefore, leadership should be given to members in a horizontal organizational structure rather than an authoritative vertical structure for the development of the beauty industry in accordance with the trend of the times. If you let them have psychological empowerment like this, they will develop positive thinking and fulfill the goals and responsibilities. Then, job satisfaction will result in positive changes such as long-term service and a decrease in turnover.

This paper is a study on the relationship between self-leadership, self-determination theory, and pro-social service behavior of beauty workers and whether it is related. There have been many studies on the existing self-leadership and self-determination theory, but studies on the relationship between the prosocial service behavior of beauty workers are insignificant. Therefore, this study aims to investigate the relationship between self-leadership, self-determination, and pro-social service behavior of beauty workers to explore the direction of efficient service of beauty workers. As a result of analyzing the relationship between self-leadership, self-determination theory, and prosocial service behavior, all three factors were found to be related, and company-level help is also needed to perform tasks autonomously. Eventually, a horizontal atmosphere must be created and internal motivation must be created to come out as a service action. Efforts should be made to create such a system not only for beauty workers but also for the entire beauty industry. It is necessary to prepare an incentive to develop self-leadership, self-motivation, and pro-social service behavior of beauty workers, which can be a way to improve job autonomy and quality of service in the beauty industry.

As a result of synthesizing the advice of experts in facial prosthetics, customized prosthetics for special cosmetics, and medical device manufacturing and sales experts, work competencies that require '3D printing based on digital work methods' are required. It was confirmed that 'prosthesis production, 3D scanning and modeling, and 3D printing' skills are required for work competency. In order to develop a more realistic aesthetic part, more attention and research are being made on the production of implants, and prosthetic manufacturers are developing materials that can extend the durability, practicality, and aesthetic life of the material. Observe the case of the human prosthesis production ear and examine the case of ear production application technology using 3D printing of facial prosthesis with special makeup. Through interviews with three face prosthetic manufacturers, we would like to explore the usefulness of facial prosthetics and ways to utilize them through collaboration with special cosmetics in the art world.

This study aims to provide accurate information through data on the perception of skin aging and anti-aging management behavior characteristics of women in their 30s in Shanxi Province, China, and to provide basic data on the development and professional management of cosmetics tailored to customers' needs in the anti-aging market. For the study, an electronic questionnaire was produced by the Wenjuanxing program, and the purpose of the study and the survey contents were read to a woman in her 30s living in Shanxi Province, China, and a survey was conducted anonymously. A total of 260 copies were distributed, and 227 copies were finally analyzed except for 33 responses that were insincere or omitted. The survey was divided into three parts: 6 questions to know the general characteristics of the survey subjects, 19 questions to know skin aging awareness, 8 questions to know anti-aging cosmetics use characteristics, and 9 questions to know professional care use characteristics among anti-aging management. The collected data were analyzed using the SPSSWIN21.0 program for Windows. The results of the study showed that women in their 30s in Shanxi Province, China, are usually aware of skin aging, but there is a lot of interest in anti-aging management. To prevent skin aging, cosmetics are used, lifestyle is maintained well, and the period of using cosmetics is 20~25 years old. Frequently used cosmetics are 'moisturizing products', and cosmetics are important to improve skin aging. In addition, “self-management (home care)” is the most common professional management, and “removing wrinkles” is the most common management. These findings show that women in their 30s need to spread knowledge about skin aging, and there is a growing interest in skin aging and anti-aging management by identifying their skin characteristics and selecting skin care that suits them. Therefore, professional management should develop a skin care program for middle-aged women in their 30s by developing a skin care program tailored to each age group, and the results of this study are meaningful in providing basic data on the dissemination of anti-aging knowledge and development and marketing of Chinese middle-aged women.

This study attempted to verify the effects of Lentinus edodesmycelium by applying a high-fat diet (HFD) to animals. For this, the Lentinus edodesmycelium 'MC-LE' was administered to the HFD animals, investigating its influence on dietary efficiency, hormones, blood and lipocytes. An experiment was performed a normal group with regular diet, HFD/Control group and HFD/MC-LE (360 mg/kg) group over 10 weeks. Compared to the HFD/Control group, the HFD/MC-LE group revealed a decrease in dietary efficiency. A significant drop was also found in the appetite-suppressing hormone 'leptin'. Furthermore, increase in the adipose (fat) accumulation-related adiponectin and decrease in IGF-1, glucose and free fatty acid accelerated lipid metabolism, confirming inhibition of fat accumulation through the size and number of fat cells. Other words, in the HFD/MC-LE group, dietary control hormone suppressed diet and accelerated lipid metabolism, reducing fat accumulation. The above results confirm that the Lentinus edodesmycelium 'MC-LE' would be useful as a material for obesity treatment.

The purpose of this study is to provide a viable roadmap that is continuously needed for the cosmetic industry by examining the current status of ESG practices at home and abroad. As a research method, a qualitative research method through theoretical and empirical considerations based on experience was used. The research results show that first, domestic and foreign cosmetic companies are sensitive to ESG management issues and are actively responding to environmental, social and governance issues. Second, given that compliance with ESG practices is a relatively recent trend, it is expected that all companies will recognize the value of ESG and contribute to the creation of an advanced consumption culture by establishing an eco-friendly culture for consumers. Finally, it will contribute to the consumer's critical attitude toward companies advertising the development of eco-friendly products, such as large enterprises and small and medium-sized enterprises (SMEs). In addition, it is expected that the contents analyzed in this study will be presented as a way to use ESG management not only for large companies but also for small businesses to raise consumer awareness of ESG management and develop the Korean cosmetic industry.

The purpose is to provide basic data necessary for marketing strategies for the beauty industry, which has rapidly shrunk since COVID- 19, by investigating the impact of beauty consumption value and service quality on store selection characteristics that have changed in the COVID-19 era. As for the effect of consumption value on store selection characteristics, the visible value of receiving discriminatory services or feeling special was the highest, and the response and empathy were the highest in the effect of service quality on store selection characteristics. In order to improve service quality in beauty services through contact with customers, it is considered most important to increase expertise through employee education, and if a service experience is provided beyond recognition and expectation through personalized services or products, it can provide services suitable for changed consumption value. In future follow-up studies, it is expected that in-depth research will be continuously conducted by expanding the size of the sample and further subdividing it.
