We investigated antioxidative activity, tyrosinase inhibitory activity, and melanin production inhibitory activity of the methanol extract of Paeoniae Radix and its fractions. The total polyphenol content of the extract was 73.45 mg/g, and content of the ethyl acetate fraction was 514.50 mg/g as the highest content of fractions. In DPPH radical scavenging ability, $SC_{50}$ values of the ethyl acetate was 3.86 ${\mu}g/ml$ as a result of greater activity in the positive control (ascorbic acid). Moreover, tyrosinase inhibitory activity of the ethyl acetate fraction showed higher activity than arbutin used as a positive control. In the cytotoxicity measurement by MTT assay, the extract and fractions were exhibited cell viabilities of 76.96~157.26% against Raw 264.7 and B16F10 cell in concentration of 10~100 ${\mu}g/ml$. In nontoxic concentration range, the ethyl acetate fraction showed strong melanin production inhibitory effect in ${\alpha}$-melanocyte stimulating hormone (${\alpha}$-MSH)-stimulated B16F10 cell. As a result, the ethyl acetate fraction of the methanol extract from Paeoniae Radix could be applicable to functional materials for skin-whitening agents.

The study was conducted to investigate functional materials as skin whitening and anti-inflammatory agent from Taraxacum officinale and Taraxacum coreanum. The total polyphenol and flavonoid content in the ethanol extract of Taraxacum officinale were found to be 64.07mg/g and 32.46mg/g, respectively. In tyrosinase inhibitory activity, the hot water extract of Taraxacum coreanum was higher than the other extracts. However, in nitric oxide (NO) scavenging ability, the ethanol extract of Taraxacum coreanum was higher than the other extracts. the ethanol extract of Taraxacum coreanum showed strong NO production inhibitory effect in lipopolysaccharide (LPS)-stimulated Raw 264.7 cell. In the cell viability measurement by MTT assay and the lactate dehydrogenase (LDH) assay against L929 cell, the extracts were exhibited fine cell viabilities and normal LDH release levels as nontoxic result in sample concentration of $250{\sim}1000{\mu}g/m{\ell}$. As a result, the ethanol extract and the hot water extract of Taraxacum coreanum could be applicable to functional materials for anti-inflammatory and skin whitening related fields, respectively.

The purpose of this study is to investigate bathing habits and behaviors, and to find out consumers' needs for washcloth, which in this case refers to Korean exfoliating cloth for bathing purpose. Subjects of this study were females of 20s to 50s living in urban area. Four hundred and twenty-six (426) women were interviewed with a structured questionnaire. Data were analyzed by ANOVA, factor analysis, correlation analysis, MDS. The results of this study are briefly summarized as follows: The most popular bathing type was shower (84.9%). Personal hygiene was one of the commonest purpose of bathing, and other purposes included health maintenance, stress alleviation, and beauty in order. Dimensions of consumer needs for washcloth were extracted from factor analysis as following properties: tactile, tough, aesthetic, constructive, and hygienic. The preference for washcloth type was related to skin type. "Non-skin damage property" was the most important parameter to choose washcloth and the other parameters included massage effect, tactile property, foaming property, and easy-to-use property.

The effectiveness of Palmarosa, Neroli and Jasmin blending oil on dry skin of rat induced by kitchen detergent are investigated. The experimental groups were divided the control group, group treated with surfactant, group treated with Palmarosa and Neroli, and group with Palmarosa, Neroli and Jasmin. Observation of epidermis and the alteration of mast cell were performed with photomicroscope. According to the epidermis morphological changes analysis, the A3 group treated with Palmarosa, Neroli and Jasmin blending oil was appeared the most similar with the control group, and the A2 group applied with Palmarosa and Neroli blending oil was sequently displayed similar characteristics. The collagen layer's breakaway resulting from Palmarosa essential oil, the collagen layer's restoration resulting from Neroli essential oil, the collagen layer's retention hyperkeratosis resulting from Jasmin essential oil were observed in the structure of the epidermal layer. In photomicrosope observation of mast cell to examine the inflammatory reactions, the increase in size and number of mast cell were showed in A1 group treated with surfactant compared to the control group. The number of mast cells definitely decreased in groups which were treated with Palmarosa, Neroli and Jasmin blending oil.

This study aims on observing the social recognition and its aspects for men taking care of their outer appearances at current point where men are rapidly rising as the main consumer in the beauty industry while their interest for outer appearances are increasing. Therefore, we observed the overall trend and changes in social recognition for male looks by analyzing the contents of newspaper articles from 1990 to 2005 that play the critical role of spreading new information trend while reflecting the interest of people of a certain era. As a result, articles related to male looks were divided into fashion, hair, skin and cosmetics, physical image, cosmetic surgery, trend related to male looks, and male oriented stores and sites, and among them, articles related to fashion and skin took up the highest ratio. Especially articles related to the trend took up the largest ratio as it reflects the properties of two industries launching new products. Moreover, articles related to male looks tended to increase generally according to timely changes, and rapidly increased especially since 2000.

화장품산업의 세계적 트렌드는 기능성화장품에서 개인별 맞춤 화장품 시장으로 발전하고 있다. 해외 유명 브랜드 제품들이, 발 빠른 대처로 보다 세분화되고 기능성을 갖춘 화장품을 생산하면서, 고가로 출시하고 있으나 개인의 다양한 피부 특성과 기호에 상응하는 맞춤 제품을 제공하진 못하고 있는 실정이다. 이러한 환경에K-Beauty의 영향을 고려하여 개인별 피부특성과 요구사항을 반영한 맞춤화장품 개발을 위해 국내에 거주하는 전국의 20대 여성들을 주 대상으로 자가 설문과 피부측정을 통해 피부특성을 분석하고 이에 따른 중요 요인들을 찾고자 하였다. 결과를 통해 국내의 20대 여성들은 지성타입의 피부와 민감성에 많은 분포를 가진 것으로 확인되었고, 선행연구의 내용과 상응하는 결과 외에 피부 타입과 민감성에는 적극적인 피부 관리를 위한 생활습관 등이 중요한 영향을 미치고 있음을 확인할 수 있었다.

Medical equipment of high frequency has been presently applied to various parts of human body and novel treatment effects have been shown by it. Recently there are many cases that high frequency apparatus has been used in dermatology as the interest in beauty has been growing. Especially used in skin, blood volume is increased by keeping surface temperature of skin at around $43^{\circ}C$ and domodex folliculorum are treated by applying high electric field. It is the aspect we consider that increasing blood volume and domodex folliculorum treatment take effect on hair loss. In this study, high frequency electrotherapy apparatus was proposed to be applied to hair loss treatment. For that, human body was experimented with varying output voltage and frequency. The adjustable switching signal for treatment was obtained from 100[kHz] to 1000[kHz] by using DSP. Stable output specific was also obtained by feedback control to protect human body. The best hair growth conditions were the output voltage of 1.2[kV], the frequency of near 300[kHz] and the maximum current of 2[mA]. We apply this high frequency electrotherapy apparatus to two bald men, 46-year-old and 45-year-old. After treatment for a month they had thick and strong hair.

As there is a growing interest in natural ingredients, they are actively being studied to improve damaged skin However, the lip cosmetics are still being inadequately studied on the exposure of lips to several stimuli and easy flow of chemical on the lips into the body. This study was conducted to make a clinical evaluation on the real effect of lip balm on lips, by extracting oil from Chamaecyparis obtusa and Lithospermum erythrorhizon that are known to play a positive role on skin. The following three natural lip balms were produced: lip balm made with Chamaecyparis obtusa(LBWCO), lip balm made with both Chamaecyparis obtusa and Lithospermum erythrorhizon(LBWCOLE), lip balm made without Chamaecyparis obtusa or Lithospermum erythrorhizon(LBWICOLE). The quality of LBWCO or LBWCOLE was evaluated to be higher than that of LBWICOLE. LBWCO and LBWCOLE had the highest satisfaction and purchase intention, respectively. As stated above, Chamaecyparis obtusa and Lithospermum erythrorhizon could be the ingredients of lip balm, and they were effective in improving damaged lips. Consequently, this study will provide opportunities to explore excellent ingredients to be used in natural lip balm. Also, studying lip cosmetics using only the natural ingredients will provide opportunities to expand positive images of ingredients for producing lip cosmetics.
