This study attempted to improve working environments for nail salon employees and expand their awareness of hazardous materials. Specifically, it measured and analyzed volatile organic compounds (VOCs) produced during manicure procedures using a direct-reading instrument and devised a plan to minimize exposure to such hazardous substances. For this, the emissions of 3 VOCs (formaldehyde, toluene, and acetone) were tested on one foreign and two domestic manicure products, using GASTEC GV-100. In terms of the reduction of VOCs emissions, they were measured and comparatively analyzed through 2 different methods, spontaneous disappearing over time and natural ventilation by opening a chamber, and the results found the following: The product manufactured by 'C' revealed high VOCs emissions. In particular, 'acetone' was the highest. However, the spontaneous reduction of VOCs over time was minor. In other words, direct reduction, such as ventilation instead of spontaneous disappearing, is necessary. The above results confirm that ventilation is crucial in nail salons.

Currently, students are in an employment structure where they have new jobs that do not yet exist, and these social changes are causing changes in career education or career decisions worldwide. Uncertainty about the future is increasing not only in Korea but also around the world, causing rapid changes in the work world, employment environment, and job environment, and is expanding beyond personal problems of youth unemployment to social and national problems. As for the survey method, a total of 481 questionnaires surveyed through the self-written questionnaire were used for beauty majors and beauticians at four-year universities with experience in beauty academies, and Duncan test was conducted as a post-verification method. Academy selection factors according to age showed statistically significant differences in plan establishment and goal selection, and academy selection factors according to the purpose of the course showed statistically significant differences from plan establishment and goal selection factors. Academic achievement according to the purpose of the course also showed significant differences, and career decisions according to gender, marital status, major, and certificate acquisition did not show statistically significant differences. It is expected to be a stepping stone for professional beauty talent by properly setting the system for factors of selecting beauty academies and raising the right perception of career paths for consumers and beauty students preparing for their own careers through various communication such as communication, counseling, and customized learning methods. In addition, the beauty industry is also expected to have a positive impact if a systematic education program is established that can be conducted in conjunction with the field by analyzing the learning attitude and the needs of practical career decisions according to academic achievement.

The emergence of multidrug-resistant microorganisms represents a global challenge owing to the lack of new effective antimicrobial agents. Essential oils could be an alternative to antibiotics because of their anti-inflammatory, antiviral, antibacterial, and antibiofilm activities. Therefore, this study aimed to investigate the antibacterial activity of essential oils as an alternative to antibiotics. In the present study, we cultured methicillin-resistant Staphylococcus aureus (MRSA) with two concentrations (0.5% and 1.0%) of 17 types of essential oils and the antibiotic oxacillin as the control. The optical density of the culture suspensions at 600 nm was determined to assess the effect of the essential oils on MRSA. At 0.5% concentration, 8 essential oils demonstrated higher antibacterial activity than oxacillin, with palmarosa, melissa true, and rose geranium showing the highest antibacterial activity. At 1% concentration, 13 essential oils showed higher antibacterial activity than oxacillin, with melissa true, palmarosa, lemongrass, and rosemary verbenone showing the highest antibacterial activity. Furthermore, essential oils isolated from leaves showed higher antibacterial ability. Overall, the antibacterial activity of essential oils against MRSA varied with the concentration, type, and extraction site. Therefore, our study provides a basis for the selection and use of essential oils for antibacterial activity against MRSA.

Although the range of choices of consumers has expanded due to the variety of products, ethical consumption is spreading by raising objections to social phenomena that cause risks such as waste of resources and destruction of the global environment. Cosmetic containers, which increase in proportion to the size of the global beauty industry, are thrown away as general waste, and research on container recycling or refilling cosmetics is lacking. The purpose is to help educational basic materials for the generation and marketing aspects for revitalization of refill cosmetics. For the empirical analysis of the study, 337 questionnaires were used as final data for beauty consumers in their 10s to 60s who have purchased refillable cosmetics living in Seoul and metropolitan areas. For the collected data, frequency analysis, factor analysis and reliability analysis, correlation analysis, and multiple regression analysis were performed through SPSS 24.0. As a result of the analysis, ethical consumption consciousness was divided into two sub-dimensions: 'trust in certified products' (45.4%) and 'resource saving' (22.3%). The motivation for purchasing refill cosmetics was extracted from two sub-dimensions: 'purchase promotion' (42.7%) and 'environmental protection' (26.6%). In conclusion, it was found that the higher the propensity for ethical consumption awareness to trust certified products, the higher the purchase promotion of refillable cosmetics and environmental protection factors. This study has regional limitations, and in relation to the above study, we expect meaningful and active studies on the effect of refill cosmetic consumption on the sustainability management (ESG) of beauty companies. Consumers expect it to be an index to measure corporate social responsibility activities.

Although many plants have been investigated for their antifungal activity against candidiasis, more treatment options remain needed. This study evaluated the antifungal activity of 19 essential oils against Candida albicans. Nineteen essential oils, at concentrations of 1% and 0.5%, were added to cultures of C. albicans and incubated at 37℃ for 18 h. The optical density was measured at 600 nm. The antifungal activity of the essential oils against C. albicans was dependent on concentration and the extraction site. At 0.5%, essential oils from thyme, palmarosa, and lemongrass displayed higher antifungal activities than fluconazole, suggesting that they are effective against C. albicans. The essential oils of eucalyptus, rosewood, and lavender showed the highest activity at 1% concentration and may be used as antibiotics individually. In addition, the essential oils extracted from leaves, such as thyme, were found to have higher antifungal activity than those from other sites.

The purpose of this study is to use a total of 339 questionnaires through SPSS 24.0 to understand the effect of SNS beauty content usage characteristics and hair style interest on hair management behavior by age, and the results of this study are as follows. First of all, hair management behavior according to SNS beauty content had a positive effect on SNS interest and reliability from teenagers to those in their 50s and older. However, it was confirmed that SNS reliability was somewhat less influential. Second, hair management behavior according to hair style interest showed a positive influence on hair style transformation by age group from 20s to 50s, excluding teenagers. In the conclusion and suggestion of this study, it was found that all age groups are interested in SNS, and the higher the interest in hairstyle, the greater the influence on hair management. However, as the reliability of SNS is low, it is necessary to pay attention to increasing the reliability by providing high-quality and good information on SNS beauty content. We hope that research on the utilization of beauty content according to gender will continue in the future.

The purpose of this study was to investigate the correlation between soybean koji prepared with Aspergillus oryzae and effects of skin care. For the 12 weeks from May to August 2018, 40~60s women participated in clinical trials. The control group consisted of nonfermented soybean and the experimental group was soybean koji, a fermented bean. And before and after soybean koji intake, the count of pores, depression, wrinkle, brightness, redness and yellowness of the facial skin were measured and compared. Research result, the pores, depression and wrinkle decreased in the experimental group 0.6 times (p<.01), 2.7 times (p<.001) and about 5.6 times (p<.001) more than the control group, respectively. On the other hand, the control group showed no significant difference in all three items. In addition, compared to the control group, the brightness of the experimental group increased 1.8 times (p<.001), the redness decreased about 1.3 times (p<.001) and the yellowness decreased about 2.6 times (p<.001). The experimental group showed a high improvement in depression (15.79%), wrinkle (12.79%), and the changes in brightness (5.07%), redness (10.04%) and yellowness (7.64%) were more alleviated compared to the control group. In conclusion, soybean koji was more effective in skin beauty such as depression, wrinkle and skin tone, compared to non-fermented soybean. Through the results of this study, confirmed the potential of soybean koji as a material for inner beauty. Finally, I expect this study will be used as basic data for nutrition and beauty.

This study analyzed the frequency of each research by setting classification criteria of the presentation time, research topic, research object, and research method of the research to understand the research trend related to semi-permanent makeup. From 2000 to 2019, 77 articles were published in Korea, which includes 28 dissertations and 49 journals. The quality and quantity of research has grown dramatically 59 items over the past five years. In terms of research topics, 50 items(63.93%) are related to satisfaction/preference/real condition, 16 items(20.77%) are related to design/technical/material/education, 8 items(10.38%) related to legalization, and 3 items(3.89%) related to hygiene/harmabilities/infection. In terms of research methods, human objects were the prevailing method(60 items, 64.93%), literature studies through material objects such as literature and experimental studies, through human/material objects were poor(17 items, 36.07%). The subjects related to satisfaction/preference/real condition and hygiene/harmabilities/infection were concentrated on research through human subjects, while the rest of the subjects has chosen relatively various research methods such as literature and experimental studies and research object such as human/material objects. Although the importance of the subject related to satisfaction/preference/real condition has been highlighted by the recent growth of the semi-permanent makeup market, the subject, which shows an overwhelming proportion compared to other subjects, focuses on the method of collecting the results of the questionnaire through various human subjects, which is a decisive factor in the bias of semi-permanent makeup-related research. Semi-permanent makeup shows a fundamental vulnerability due to lack of academic integration with the beauty detail field, and legal regulation of the procedure. Therefore, following effort should be put into the subject to overcome such limitations. Design/technique/material/education topics should be linked to existing makeup art, beauty materials, beauty equipment, beauty marketing and beauty education research. Hygiene/harmabilities/infection-related topics should be associated with existing Cosmetic Dermatology and cosmetic basic science research. As the discussion of the legalization of the semi-permanent makeup has been sparked, the topic of legalization is also urgent. In particular, there is a need for research on the enactment of the Korean semi-permanent makeup and the cases of foreign-related laws. Be vigilant so that satisfaction/preference/real condition topics are not settled as a means of avoiding academic challenges or problems. In the future, we must refine and diversify the research related to the semi-permanent makeup.

In recent years, the age to start using makeup is getting younger. As the amount of usage of color cosmetics increases, the lip cosmetics have gotten uncomparably diverse in comparison with the past. Due to the functional characteristic of lips, there is a high possibility for the ingredients of lipsticks or lip glosses to enter the human body. So it is necessary to do research on the safety and hygiene of the cosmetic ingredients. This study investigates the hygiene awareness which affects the safety and stability of the cosmetics for lips. This study also investigates the effect of hygiene awareness on the eagerness to purchase lip cosmetics. This study surveyed women in their teens and older for two weeks from November 2, 2018. Four hundred twelve returns were analyzed. There were 37 questions in the questionnaire such as actual conditions of lip cosmetics use, hygiene awareness, purchase eagerness, and general traits. The collected data were statistically analyzed using SPSS v. 21.O statistical package program. To verify the reliability, Cronbach's α coefficient was calculated, and descriptive statistical analysis and correlation analysis were carried out. The results showed that 'internet' was the most frequent information source on the usage (51.2%) and that the awareness at the point of purchase on the last date of distribution and the expiration date was low. The hygiene awareness on the lip cosmetics was revealed to be moderate. The purchase eagerness was highly affected by the opinions of the sales people or the opinions of friends and acquaintances. The duration of the cosmetic use and the recommended duration of use are related to the hygiene, safety, and stability. It turned out that the awareness on such durations was low. It is necessary, we think, for the consumers to know how to use the cosmetics safely, how long they can use the cosmetics after opening them, and act accordingly. It can be concluded, in another words, that providing consumers with the information on the safety of cosmetics affects the level of purchase satisfaction.

The purpose of this study was to investigate the clinical effectiveness of human adipose-derived stem cell- conditioned media (ADSC conditioned media (ADSC-CM) as a cosmetic material. To evaluate the effects of cream containing ADSC-CM 5% polymersome on human skin, subjects applied 0.8g of the research samples over the whole face for 28 days. In the experimental group (E), the moisture content increased by 12.4 percent(p<.001), and the TEWL was 5.5% increased while it was increased by 22.6% in the control group (C). Melanin index decreased by 1.6%(p<.05) and erythema index decreased by 3.2% in E(p<.01). Compared to the pre-test, the post facial skin tone was increased by 0.2% in E. E showed improvements in overall size of eye wrinkle, depth, and width by 19.1%, 12.5% and 4.3%, respectively(each p<.001). Skin roughness decreased by 9.9% in E(p<.001). Gloss value increased 7.2% in E(p<.001). In conclusion, the effectiveness of ADSC-CM polymersome was verified on all items including skin moisture content, TEWL, melanin, erythema, facial skin tone, eye wrinkle, skin roughness and gloss value. These results demonstrate that cream contained ADSC-CM polymersome has the clinical effectiveness as cosmeceuticals.

To use kimchi lactic acid bacteria as a cosmetic ingredient, screening was performed. The antioxidant activity of the heat-killed lactic acid bacteria isolated from kimchi was measured. Of the 134 strains of lactic acid bacteria derived from kimchi, 26 strains were selected based on the culture suitability such as growth rate and acid resistance. DPPH assay, ABTS assay, FRAP assay, nitrite radical scavenging activity assay, and total phenolic contents were measured for 26 strains, and with Lactobacillus rhamnosus KCTC 5033 as a reference, 5 strains were selected through DPPH assay, 2 strains through ABTS assay, 13 strains through FRAP assay, 5 strains through nitrite radical scavenging activity assay, and 10 strains through total phenolic contents measurement. Among them, Lactobacillus sp. 7-2, which showed excellent antioxidant potential in all experimental methods was isolated, and as a result of identification through 16s rRNA, it was found as Lactobacillus paracasei. This strain showed 1.09-1.90 times superior antioxidant potential than L. rhamnosus KCTC 5033, which is widely used for research purposes according to the method of measuring antioxidant potential. Thus, from kimchi, it was possible to isolate lactic acid bacteria which can be used as antioxidants in cosmetics.

Objectives: This study attempted to investigate the effects of castor oil on hair after preparing and applying hair-care formulations to damaged hair. Methods: With different castor oil contents (0g, 1g, 2g, 3g), hair care formulations were prepared. After applying them to hair samples, changes before and after the application were measured and comparatively analyzed. Results: L* values decreased after the application of the hair care formulations. In addition, a small increase was observed in a* and b* values. According to the measurement of de-coloring values, 20.11 NTU was found after Day 1. From Day 4, no de-coloring was observed. In terms of tensile strength, all samples using level 7 and 9 increased. According to the analysis of absorbance using methylene blue, the results slightly decreased after the application of the formulations. As for gloss, no significant difference was observed in all samples. Conclusion: When castor oil was applied to damaged hair, tensile strength increased while absorbance decreased, confirming improvements in hair texture.
