Background & Objective : Microneedle therapy system(MTS) is popular these days. However, there are few reports about it in oriental medicine academia. This study is performed to evaluate the effect of MTS on acne patients. Methods : This study was conducted to evaluate the effect of MTS. Seven patients were treated for 7 weeks. Follow-up was performed after the treatment with Janus facial analysis system, skindex-29 and Digital Infrared Thermographic Imaging machine. Satisfaction degree and inconvenience were asked from the patients. Results and Conclusions : Microneedle therapy system(MTS) was good for acne like pore, wrinkle, spot(polarised), sebum, porphyrin and skin tone.

Objectives : The aim of present study was to investigate the skin characteristics of twenty-five healthy Korean subjects. These results can be used as basic data for the development of future herbal applications. Methods : Skin type, hair and scalp condition, water content, sebum content were investigated through the measurement of skin conditions and subjective questionnaire survey to know the skin characteristics of subjects. Results : Most of subject has 'Dry Skin' and they have trouble about their keratin(dandruff), scalp itching, alopecia, hair texture, scalp moisture. Conclusions : More studies are needed to investigate the skin characteristics of healthy Korean subjects.

Objectives : This study was carried out to examine the change of scalp and hair condition and to evaluate the efficacy of hair growth, subject's satisfaction and safety of the Narasoo healing shampoo and Hair tonic Methods : We offered 25 subjects Narasoo healing shampoo and Hair tonic and observed the changes among the starting point, 3rd week and 6th week. Study methods include the measurement of water and sebum content of the scalp, photo of scalp and hair, thermographic images and questionnaires. Results : It is estimated that Narasoo healing shampoo and Hair tonic have the positive effects on increase of water contents hair gloss, removal of excessive hair keratin, facilitation of hair growth, and decrease of sebum contents. Conclusions : Several meaningful effects of Narasoo healing shampoo and Hair tonic are observed in this study. Additional research is needed forward.

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. Especially the meridian massage played a role of enhancing the effect of the cosmetics containing Ginkgo biloba.

In this study, we aimed to determine the various effects of Osmanthus fragrans (O. fragrans) flower extract on the skin in order to utilize it as a cosmetic material. For this purpose, Osmanthus fragrans flower extract (OFFE) of Jeju Island was prepared and used in the experiment. The experiments were evaluated by the quantitative real-time polymerase chain reaction (qRT-PCR) and lipid droplet staining assay. First, the OFFE decreased the gene expressions of three representative pro-inflammatory cytokines (IL-8, IL-6, and IL-1α) and an inflammation-related enzyme, PTGS2 induced by poly I:C in epidermal keratinocytes. In addition, the OFFE increased the gene expression levels of collagen (COL1A1) and elastin (ELN) in dermal fibroblasts. Further, the OFFE showed the inhibitory effect in sebum production by linoleic acid in sebocytes. Therefore, from this study, it is expected that OFFE can be used as a natural cosmetic material for anti-inflammatory, anti-aging, and sebum inhibitory efficacy.

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.
