In the aged skin especially in the face and eyelid, deep and slight wrinkles are one of the remarkable phenomena of aging and the cause of wrinkle is various. Among the cause of wrinkles an oxidative stress plays an important roles in wrinkle formation process. It caused the lipid peroxidation of cell membrane, the increase of the MMPs(MatrixMetalloProteinase) gene expression and cellular DNA damage. These ROS induced materials may cause the degradation of collagen matrix system in the dermis and cause the formation of skin wrinkle. So, it is very important for protecting skin wrinkle formation to regulate ROS activity. In this study, we developed one active ingredient having multi functional activities such as activation of collagen synthesis, inhibition of MMPs activity, lipid peroxidation and free radical scavenging activity and inhibition of free radical induced DNA damage in vitro. Pericarpium castaneae extracts showed collagen synthesis increase in Normal Human Fibroblast and the inhibition of elastase activity (IC$\_$50/ of Elastase: 43.9$\mu\textrm{g}$/㎖). It showed also anti-oxidative activity (IC$\_$50/ : 48$\mu\textrm{g}$/㎖) and free radical scavenging activity(IC$\_$50/: 7.6$\mu\textrm{g}$/㎖). Conclusively, Pericarpium castaneae extracts may be used as an ingredient for new anti-wrinkle cosmetics.

Cosmetic mask is one of the traditional cosmetic product and is used to keep skin healthy and beautiful through moisturizing effect, cleansing effect and acceleration effect on microcirculation. There are several types of cosmetic mask such as peel-off type, tissue-off type, wash-off type and cotton sheet type immersed in cosmetic water. It is important for cosmetic formulators to develop an adequate type of cosmetic mask that meets the needs of the target consumers because each type of cosmetic mask has benefits and problems in its usage and efficacy. Polyvinyl alcohol (PVA) is widely used as an active ingredient of peel-off type cosmetic mask and the physical property of the PVA film changes with the usage of other ingredients. We studied the change of physical properties of the film containing PVA by formulating peel-off type cosmetic mask with the variation of humectants. Methylguceth-20 and glycereth-26 reduce the interaction between skin surface and PVA film without serious weakening of tensile strength and they can alleviate irritation. Glycerin, urea and betaine help PVA film soften and they also have excellent efficacy as humectants.

The study aims to investigate the effects of brand value in the oriental medicine cosmetics market, as perceived by consumers, on brand satisfaction, brand loyalty, and purchase intention. The subjects were Korean and Chinese female consumers, the primary consumers of oriental medicine cosmetics. A total of 615 sample surveys were analyzed from consumers who have experience using oriental medicine cosmetics. Out of the sample, 264 respondents had used Oriental medicine cosmetics for one to four years, 199 respondents for more than four years, and 108 respondents for three months to a year. Based on existing research, we categorized the value of oriental medicine cosmetics brands into four dimensions: emotional, social, functional, and epistemic values. Whether brand satisfaction and brand loyalty can be mediating factors in brand value influencing purchase intention was inspected through several hypotheses. As a result, except for the epistemic value factor, the brand value factors were found to have a positive effect on brand satisfaction and brand loyalty. In addition, emotional, social, and functional brand value factors influence purchase intention through brand loyalty, and it was found that brand loyalty is an important factor for oriental medicine cosmetics consumers, however mediator effects did not appear for brand satisfaction.

The data on Chinese women living in China in their 20s was collected using an online survey. Three hundred twenty-seven questionnaires out of a total of 330 questionnaires were used for statistical analysis. The survey was conducted from January to February 2014. Eighteen questions on shopping tendency and eight questions on the properties of cosmetics were analyzed using a 5-point Likert scale. Data was analyzed by Descriptives, Factor Analysis, Reliability Analysis, ANOVA and Cluster Analysis, and SPSS 21 statistical program. In accordance with the analyses, the shopping tendency comprised a showing-off tendency, pleasure-seeking tendency, and practicality tendency; the properties of cosmetics were classified into conformity and functionality. On the basis of the elements in the shopping tendency, the female consumers were categorized into a low involvement consumer group, high involvement consumer group, and hedonic consumer group. The Chinese women emphasized conformity or functionality of cosmetics more than the Korean women regardless of the countries where they lived. Regardless of shopping types or countries where they lived, the Korean and Chinese women in their 20s emphasized functionality over conformity of cosmetics. Furthermore, Chinese women living in Korea showed a similar shopping tendency to Chinese living in China.

Tests of stability and toxicity, and clinical evaluation of anti-acne activity suggest that cryptotanshinone, a constituent of the roots of Salvia miltiorrhiza Bunge, is an effective active ingredient for acne vulgaris treatments. Acne vulgaris, called acne or pimples, is the most common disease of the pilosebaceous follicle unit of the skin. It affects nearly 80% of people between the ages of 11 and 30. Approximately 30% of teenagers have acne of sufficient severity to require medical treatment. Acne is a follicular disorder of the skin. It occurs in specialized pilosebaceous units on the face and body. Acne develops when these specialized follicles undergo pathologic alterations that result in the formation of non-inflammatory lesions (comedones) and inflammatory lesions (papules, pustules and nodules). An abnormality of keratinizing epithelium of these follicles, thought to be due to the action of sebum synthesized and secreted by the androgen-sensitive sebaceous glands, leads to inflammation induced by the follicular bacterium Propionibacterium acnes. Therapy involves treatments that modify these pathogenic factors and includes drugs with antikeratinizing, antibacterial and antiseborrheic actions. Acne vulgaris is a very frequent disease, seen primarily in adolescents, involving the sebaceous follicles. Acne vulgaris is characterized by a great variety of clinical inflammatory and non-inflammatory lesions: comedones, papules, pustules, nodules, cysts and scars. Acne vulgaris is a multi-factorial disease. Although its pathogenicity is unclear, extensive studies have shown that hyperseborrhea, superinfection by P. acnes and endocrinologic androgenic changes play a role in the development of acne vulgaris.
