This study investigated differences in cosmetic buying behavior and personal characteristics between cosmetic involvement groups. Cosmetics buying behavior refers to reason for using cosmetics, use of information sources, selection criteria, place of purchase, use/non-use of cosmetics, purchase propensity, purchase frequency, purchase amount, and satisfaction with cosmetics. Personal characteristic contains pursuing image, age, residence area, job, and average household monthly income. Data was collected from 5-10 December 2016, from 308 females in their 20s using an internet survey. The analysis included descriptive statistics, t-tests, Mann-Whitney U tests, and chi-square tests. The respondents were divided into two groups (a high cosmetic involvement group and a low cosmetic involvement group) according to the degree of cosmetic involvement. The results of t-tests revealed significant differences between groups in terms of reasons for using cosmetics, use of information sources, selection criteria, purchase frequency, place of purchase, use/non-use of cosmetics, and satisfaction with cosmetics. The results of Mann-Whitney U tests highlighted a significant difference in purchase frequency between both groups. The results of chi-square tests indicated significant differences in purchase frequency, purchase amount, pursuing image, and average household monthly income. However, no significant differences were evident in terms of purchase propensity, age, job, and area of residence between groups.

In Korean Cosmetic Act, four uses of functional cosmetics are recognized: skin whitening, anti-wrinkle, UV protection or suntan. Cosmeceuticals, one of the functional cosmetics, have been specifically developed for medical and cosmetic benefits. However, the uses of cosmeceuticals in patent applications are not limited to those of functional cosmetics, and the number is increasing with variety of medical use claims such as anti-inflammatory, prevention of hair loss, or obesity in cosmeceutical patent applications. Since some of the cosmeceutical use claims are not clearly distinguished from medical use claims in pharmaceuticals, there has been a controversy over the extent of granting patents regarding the medical use of cosmeceuticals. In this article, we have investigated the range of medical uses in patented claims of functional cosmetics, summarized examiners' views and discussed the examination practice of cosmetic-related inventions in the United States, Europe, and Japan.

The purpose of this study was to examine the differences of the information searches and purchasing behavior Korean men in their 20s and 30s, focusing on cosmetic involvement. Research methods consisted of qualitative and quantitative approaches. For the qualitative approach, in-depth interviews and participant observations were conducted to investigate male customers' cosmetic characteristics in information searches and purchasing behavior. Then, the study conducted a quantitative study methodology based on the questionnaires from the in-depth interviews, participant observations, and literature review. The study surveyed 340 Korean men in their 20s and 30s. The cosmetic involvement of the target group was classified into the amusing high-involvement group, the rational low-involvement group, and the obligatory high-involvement group. The results from this study indicated that the groups of male customers classified by cosmetic involvement showed statistically significant differences in terms of information searches and purchasing behaviors. Especially, the obligatory high-involvement group generally displayed high-involvement traits likewise the amusing high-involvement, was more similar to the rational low-involvement group regarding cost effectiveness than the obligatory high-involvement group. Moreover, the classifications of men generally had different characteristics of cosmetic purchasing behavior and information searches than women. This study has a distinctive significance compared with other studies in discovering differences of cosmetic purchasing behaviors of Korean men in their 20s and 30s' cosmetic involvement groups classified using qualitative and quantitative approaches.

The skin barrier plays an important role in maintaining healthy skin by preventing external irritation and water loss in the body. In the skin, hyaluronic acid (HA) is synthesized by the enzyme hyaluronic acid synthase (HAS), which functions as a natural moisturizing factor and is involved in maintaining water retention and barrier function. Therefore, in this study, the effect of the Prunus yedoensis bark ethyl acetate fraction (PYBEAF) on HA synthesis in HaCaT cells was confirmed. Cytotoxicity evaluation was performed through MTT assay, and the amount of HA synthesis in HaCaT cells was confirmed through ELISA through PYBEAF treatment. The levels of HAS-2, HAS-3 mRNA expression were analyzed using qRT-PCR, and the protein expression level and signaling pathway were confirmed through western blotting. Consequently, PYBEAF was involved in the MAPK and CREB signaling pathways, increasing the amount of HA production through HAS-2 synthesis. This suggests that PYBEAF is effective in improving barrier function by increasing HA synthesis, which plays an important role in moisturizing and maintaining skin moisture.
