The purpose of this study was to investigate the effects of dietary habits and nutrient intakes on skin condition of female university students. The subjects were 95 female university students in Daegu. This study examined anthropometric measurements, dietary intake, food intake habits and skin condition (moisture, elasticity, sebum (U-zone, T-zone), pores, evenness and melanin pigmentation. The subjects in this study had an average age of 21.4, an average height and weight of 161.2 cm and 52.9 kg, respectively, and the average body mass index (BMI) was 20.3 $kg/m^2$. The means of skin elasticity, pores, evenness, and melanin pigmentation were within the normal range of women in their 20s and the skin moisture state was slightly lower than the normal range, which showed a dry tendency. The sebum in the U-zone and the T-zone was lower than the standard values, which showed less secretion in both areas. The subjects with high nut intake showed a better skin pore state (p < 0.05). Those with a high intake of instant foods showed a sig-nificantly low skin moisture and a significantly higher sebum rate (p < 0.05). The group with high skin elasticity and the group with less melanin pigmentation showed a significantly low animal protein intake (p < 0.05). The group with high skin elasticity also showed a significantly higher vitamin A and niacin intakes as well (p < 0.05). The group with high skin evenness showed a significantly lower animal lipid intake and a significantly higher vitamin E intake (p < 0.05). In addition, those with high skin elasticity and evenness as well as low melanin pigmentation showed a tendency of high intake of antioxidant vitamins, such as vitamin A, carotene, vitamin C or vitamin E. In summary, a moderate intake of plant-based products and also the antioxidant vitamins within such products seems to have a beneficial effect on maintaining a healthy and good skin condition.

Objectives: We investigated the physical effects of the cosmetics containing Ginkgo biloba. with meridian massage on human skin by using non-invasive instruments. Methods: We made cosmetics containing the extract of Ginkgo biloba. and measured physiological effects such as skin moisturization, blood flow, skin color, sebum secretion, skin evenness of volunteers applied the cosmetic products with meridian massage for 2 weeks. Results: Topical applications of w/o cream that 1 % Ginkgo biloba. was emulsified, showed significant improvement of blood flow, water contents and $L{\ast}$ value of the face skin. And the skin evenness, sebum contents and skin surface smoothness were improved after 2 weeks. Conclusions: The combination of cosmetics containing the extract of Ginkgo biloba. with meridian massage improved the physical properties of human skin during a treatment.

본 연구에서는 목서(Osmanthus fragrans, O. fragrans) 꽃 추출물을 화장품 소재로 활용하기 위해 피부에 대한 다양한 효능을 확인하고자 하였다. 이를 위해 제주산 목서 꽃 추출물(O. fragrans flower extract, OFFE)을 제조하여 실험에 이용하였다. 실험은 실시간 중합효소 연쇄반응인 qRT-PCR과 lipid droplet 염색법으로 평가하였다. 먼저 OFFE는 표피 각질세포에서 poly I:C로 유도된 3 종의 대표적인 전염증성 사이토카인 (IL-8, IL-6, IL-1α)과 염증 관련 효소인 PTGS2의 유전자 발현을 감소시켰다. 또한 OFFE는 진피 섬유아세포에서 콜라겐(COL1A1)과 엘라스틴(ELN) 유전자 발현을 증가시켰다. 더 나아가 OFFE는 피지세포에서 linoleic acid에 의해 유도된 피지 생성을 억제하는 효능 보여주었다. 따라서 본 연구를 통해 OFFE은 항염, 항노화, 그리고 피지억제 효능을 위한 천연 화장품 소재로써 적용이 가능할 것으로 기대된다.

Purpose: This study was performed to identify skin health status and the factors influencing skin hydration in the institutionalized elderly. Methods: The subjects were 139 elders living in 2 nursing homes in Seoul. Data for skin health status were collected by measurement of skin hydration, sebum, trans-epidermal water loss and pH using Corneometer, Sebumeter, Tewameter and Skin pH-meter on face, flank, arm and leg. Baseline data were collected by a structured questionnaire. The data were analyzed by SPSS/WIN 12.0 program. Results: Skin hydration and pH were relatively low especially on arms and legs but sebum and TEWL were not low, relatively. There were significant differences in skin health status according to gender, smoking, alcohol intake, and bath cleanser. There was significant positive correlation between skin-hydration and bath-time, TEWL and bath-frequency. Smoking, bath-cleanser, bath-time. pH and gender were identified as the significant influencing factors of skin hydration. Conclusion: Smoking, bath-time and pH need to be considered as important control factors for increasing skin health status in the institutionalized elderly.
