The purpose of this research is to provide the basic data for the development of make-up color application system, based of Korean's skin tone and the preference in make-up color to enhance the effectiveness of the education of beauty in universities. The research was conducted by the previous studies, the analyses of sale's rate of hue-cosmetics, the analytic experiment of color of cosmetics by using Spectrum Color Analyzer and other experimental researches. This research, based on the results of three preliminary researches, shows the result of evaluation from perceivers which has been come out from the experiment of having one model in her twenties being changed with twenty-two different conditions of make-up. Here follows the result of the research. Firstly, there was difference on perceiving images in terms of the gender of perceivers and especially male-group tend to have clearly perceived the gap between elegance-greyish purple, orange-natural, red-classic on monochrome make-up and contrast make-up. Secondly, in terms of lip-colors, salmon pink and pink was regarded positively to both female and male subjects and to male subjects, greyish purple was thought to be better on darker skin-tone and to female subjects, better on lighter skin-tone. Thirdly, on image make-up, romantic gives intelligent image regardless of skin-tone and gender, especially gives more positive looks to male subjects. Natural and classic elements were perceived more positively on darker skin-tone and had bigger perceiving gap in female subjects. Fourthly, in preference rate, male subjects normally preferred the look with make-up than female subjects did and salmon pink and pink lip color was preferred on the darker skin-tone.

The objectives of this research were to investigate the relationship between purchase behavior and consumer dissatisfaction of cosmetics at internet shopping malls, and to examine how the purchase behavior and consumer values influence the consumer dissatisfaction. Subjects were 212 females in Seoul who had experiences of cosmetic shopping at internet shopping malls. Consumers showed highest dissatisfaction when the purchased cosmetics were different from the products showed at internet shopping malls. The dissatisfaction with consuming system was higher than buying system or transporting system. The higher the expense and frequency of cosmetic purchase, the lower the consumer dissatisfaction of buying system. Females of 18 to 24 years old purchased color cosmetics more than females of 25 to 39 years old did. Females of 25 to 39 years old purchased functional skincare products more than females of 18 to 24 years old did. The cosmetic purchase expense of older groups was higher than that of younger one. The more consumers spent time on the internet, the more frequent they bought the cosmetics at internet showing mall. Consumers were most willing to buy basic skincare products at the internet shopping mall (42.9%). The consumer dissatisfaction with cosmetics at internet shopping malls was influenced the most by the happiness value(-) and the next by the responsible value, the frequency of cosmetic purchase at internet shopping malls(-) in order.
This study aims to prove the changes, development and social background of Korean male cosmetics over the period of 2000-2010. There were total 574 articles written about male make-up and cosmetics in Chosun Daily, Joongang Daily and Donga Daily, which are the top three Korean local daily newspapers in terms of sales revenue for that period. These articles were analyzed together with social background research from various books and daily newspapers. The analysis of articles was divided into different categories; such as foundation cosmetics, color cosmetics, hair, and the social background. It was found that the articles related to foundation cosmetics were written the most, the articles related to male appearance management were second, articles on other items including how to manage the skin being the least. As for the social background of Korean male cosmetics, first of all, a change in social recognition can be pointed out. The traditional understanding of gender roles has changed, men's appearance management has started to be regarded as a competitive talent, and at the same time, the esthetic viewpoint for men also has changed. One example is the newly made popular term, "flower-handsome man", which shows the new trend of favoring males with nice skin. Second, the expansion of mass culture can be pointed out. As consumers can get information and fashion trends easier and faster, the fashion spreads fast, and this has led to the generalization and popularization of the sense of beauty. Third, the development of scientific technology and medical science can be pointed out. Thanks to the progress in those areas. the extension of youthfulness has become possible and the cosmetics industry was also affected greatly, as shown in the market spread of functional products for anti-ageing and wrinkle control as the interest in anti-ageing has grown. There are benefits from the development of scientific technology, but the problem of environmental pollution has appeared due to machinery and industrialization and thus the issue of well-being has been raised. Rising interest in naturalism, pro-environmentalism and organic cosmetics has influenced the cosmetics industry. In addition, the quantity of ultraviolet rays exposed to our skin has increased due to the air pollution caused by the destruction of environment, leading to increased usage of sun block lotion. Lastly, the influence of consumer society and the expansion of consumerism culture can be pointed out. In the modern society, consumption acts not only as the use of products and services but it also has an important role of mediating individuals with others and the society. The market for male cosmetics has been expanding and the number of men putting on make-up has been increasing rapidly. Therefore, this study is meaningful in that the analysis of the mode of change and the social background are an essential process in order to provide a direction for the future market for male cosmetics.
The purpose of this study is to investigate the origin of make-up and the beginning of 'Yoenji' cosmetics. The result of this study is as follows: 1. The origin of make-up can be summarized as being originated from the sexual display to maintain tribes and incantatory religion for their existence. The reason for the preference to Yeonji in make-up is that Yeonji has a characteristic of red in color, which seems to hold effective for the sexual display of human beings. 2. The origin of Yeonji (焉支; Safflower) was from Egypt, but its inception as a cosmetic product was with Huns. 'Yeonji' was a term of Hungro race, and was also called Unji (焉支), Yeonji (燕支), Inji (姻支), Urji (閼氏), following the similarity of the sound. These terms were not only the interpretation of the Hunnish sound into Chinese, but also allegorical expression. Unji (焉支), Yeonji (燕支), and Inji (姻支) meant Safflower. Urji(閼氏) meant 'Empress' or 'Wife,' which was pronounced Yeonji (燕支) and Asi (閼氏).

Melanin is one of the most important factors affecting skin color. Melanogenesis is the bioprocess of melanin production by melanocytes in the skin and hair follicles and is mediated by several enzymes, such as tyrosinase, tyrosinase related protein (TRP)-1, and TRP-2, MITF. In this study, we investigated the effect of Artemisia fukudo Makino extracts on tyrosinase activity and melanin production as natural products of whitening functional cosmetics. Melanin content in murine B16F10 melanoma cells were decreased by Artemisia fukudo Makino extracts in a dose-dependently. In addition, the inhibition of tyrosinase activity of Artemisia fukudo Makino extracts showed to decrease tyrosinase activity as the concentration of ${\alpha}-MSH$ was increased. Furthermore, western blot analysis revealed that Artemisia fukudo Makino extracts significantly downregulated the expression of tyrosinase, TRP-1 which treat of ${\alpha}-MSH-induced$ melanogenesis in murine B16F10 melanoma cells. As a result, Artemisia fukudo Makino extract showed functionalities as an effective whitening agent to inhibit melanin formation.
In this paper, we propose an automatic cosmetic foundation recommendation system that suggests a good foundation product based on the user's skin color. The proposed system receives and preprocesses user images and detects skin color with OpenCV and machine learning algorithms. The system then compares the performance of the training model using XGBoost, Gradient Boost, Random Forest, and Adaptive Boost (AdaBoost), based on 550 datasets collected as essential bestsellers in the United States. Based on the comparison results, this paper implements a recommendation system using the highest performing machine learning model. As a result of the experiment, our system can effectively recommend a suitable skin color foundation. Thus, our system model is 98% accurate. Furthermore, our system can reduce the selection trials of foundations against the user's skin color. It can also save time in selecting foundations.

Lip make-up products can be easily taken into body with food. For this reason, those products are requires to meet lots of qualifications compared with other cosmetic products. In addition, concerns about safety on synthesized tar pigments is constantly issued. Thus, demand of natural pigments is gradually increased and many kinds of natural pigments have been developed. However, there are some problems when natural pigments are applied to cometic products instead of synthetic ones. There is a reason that most of natural pigments consist of hydrophilic materials of sort of anthocyanin, but the existing lip make-up products is anhydrous oil dispersion type without water consisting oil and wax. Therefore, when watersoluble natural pigments are applied to anhydrous lip make-up products, color expression is lower and phase separation occurs due to the instability of the product. In addition, natural pigments have disadvantages that they can easily change by pH, heat and sunlight. There are troubles of stability because it is not easy to adjust for these factors in case of anhydrous forms. Aim of study is to develop lip make-up products which have not only safe to human but being high in expression of color by using natural pigments and securing stability of colorant as natural pigments are offered to polyol in oil emulsion. Then, lip make-up products which have heavy moisture while having not dryness that is created when the moisture evaporates are developed.
This study was attempted to develop the physicochemical ad morphological stability test methods for the cream and lotion formulations among the cosmetic foundations and to provide the guidance for the stability methods with respect to basic emulsions and creams. With these developed stability test methods, we can evaluate the expired date or life time of the available basic cosmetics, especially basic lotions ad creams. Also, the stability test methods established in this study can be used as a guideline to test physical and morphological stability of cosmetics in the future. Thus, we selected two types of basic cosmetics such as lotions and creams made by four different cosmetic companies ad applied them to the stability test methods depending on the temperature changes such as temperature cycling and freezing-thawing cycling test. After the temperature changes, the conductivity, turbidity, particle size, creaming ratio and pH changes of the creams and lotions were evaluated and morphological changes such as crystal formation, odor, color and feeling of the creams and lotions were also tested. As the results of the stability tests, all the tested creams and lotions except for one lotion were stable. Therefore, it may be concluded that these short-term accelerated stability tests as physical stability test depending on the temperature change study were suitable for the stability testing methods for the basic cosmetics and may be useful for the establishment of the guideline for the stability test of cosmetics.

Ascorbic acid (Vitamin C) becomes unstable in the aqueous phase by oxygen, light and alkali, etc. The properties are limited in application to cosmetics. The most important factor that determines the destabilization of ascorbic acid in the aqueous phase was tried to understand considering its molecular deformation and degradation. In this study, we changed the polyols and emulsification technique for the stability of ascorbic acid. Then we observed the color and concentration change of ascorbic acid at room temperature and high temperature ($42^{\circ}C$) for 6 weeks and identified the stability using HPLC regularly. As a result, we found that glycerin was the most appropriate polyol for stability of the ascorbic acid. Also the technique of nonaqueous emulsification stabilized ascorbic acid than P/S emulsification. Also, P/S emulsification, glycerin was more stable than propylene glycol. By the results we suggest that ascorbic acid could be stabilized by nonaqueous emulsification method and this data could be applied to stabilization methods for cosmetic products.
Objectives: Ultraviolet (UV) radiation may cause skin cancer, photo-ageing, erythema, and sunburn. Benzophenone (BP) is commonly used to protect skin from UV radiation. In Korea, sunscreen, sunblock, socalled 'blemish balm' (BB) and 'color correcting' (CC) creams, and foundation may contain from 0.5 to 5% benzophenone in order to protect skin from UV radiation. The purpose of this study is to understand the levels of benzophenone derivatives in urine among a group of university students and identify the contribution of cosmetics use. Methods: Forty volunteers (20 women and 20 men) were asked about skin type, frequency of use of cosmetics, and recognition of related health effects, etc. in a survey. Subjects were divided into several subgroups and were compared for concentration of benzophenone-1 (BP-1) and benzophenone-3 (BP-3). Their urine was pretreated with enzyme hydrolysis and solid phase extraction. Determinations of BP-1 and BP-3 in the urine were made with LC-MS/MS. Results: Among the study subjects, 82.5% used basic cosmetics at least once per day, and 77.5% used sunscreens at least once per day. The concentrations of BP-1 and BP-3 of the males were 4.36 ng/mL and 9.16 ng/mL, respectively. Those of the females were 3.98 ng/mL and 5.07 ng/mL, respectively. The use of cosmetics was positively related to urinary benzophenone levels. Conclusions: BP-1 and BP-3 were widely detected among the university students. Cosmetic use was identified as a potential source. Implications of such exposure deserve further investigation.
