황련(Coptis Japonica)의 뿌리로 제조한 황련 추출물 화장품이 민감한 피부에도 안전한지 검 증하기 위해 민감성 피부를 대상으로 인체 첩포 시험을 실시하였다. 젖산 자상 검사 결과 민감성 피부 로 판정한 총 32명의 시험대상자에게 황련 추출물을 2% 배합한 가용화 에센스를 시험대상자 등 부위에 20 ㎕ 취하여 24 h 동안 폐쇄 첩포한 후 이를 제거하고 30 min과 24 h 후의 시험 부위를 피부과 전문 의가 육안으로 관찰하여 피부 자극 지수를 산출하였다. 그 결과 육안으로 이상 반응이 확인되지 않았고 자극 지수가 총 0점으로 나타나 황련 추출물 2%를 배합한 화장품이 민감한 피부에 안전한 것을 확인하 였다. 다수의 황련 연구에서 항균, 항산화, 항염 등의 활성이 밝혀지고 화장품 소재로 이용 가능성이 보 고되고 있지만 본 연구를 통해 황련 추출물 화장품이 민감한 피부에도 안전한 것으로 나타나 향후 황련 화장품의 무자극 또는 저자극의 소재연구에서 본 연구가 기초 자료로 활용될 것으로 기대된다.

The purpose of this study was to investigate the effects that body composition, nutrient intake, and biochemical indices have on skin status, as well as their associations with skin health status, by assessing 44 female university students. The subjects were classified into 3 groups according to skin sensitivity: sensitive skin (n=11), slightly sensitive skin (n=24), and normal skin (n=9). The study included anthropometric measurements and body composition analyses, dietary intake evaluations, blood chemical analyses, and skin health status assessments. Based on % body fat, the results indicated the subjects were moderately obese (29.6%). Obesity indices were not different among the groups, but the sensitive skin group tended to have higher skinfold thickness. Dry skin was determined as the skin type of all subjects. In the sensitive skin groups, U-zone and T-zone sebum were significantly lower (p〈0.05), and spots were significantly higher (p〈0.05) than in the normal skin group. In terms of nutrient intakes, the sensitive skin groups consumed significantly lower amounts of P and vitamins A and E (p〈0.05). There were no significant differences in serum lipid fractions or total antioxidant status among the groups. In correlation coefficients analysis, skin elasticity had significant negative correlations with subscapular and midaxillary skinfold thickness, body protein, and body minerals (p〈0.05). Wrinkling had positive correlations with triceps and thigh skinfold thickness (p〈0.05). Skin evenness had negative correlations with energy intake, vitamins A, B1, B2, C, E, niacin, and zinc (p〈0.05), as well as folate and P (p〈0.01) and vitamin B6 (p〈0.001). A similar correlation tendency was observed for spots and nutrient intake, showing negative correlations with vitamins A, B6, and E, as well as folate, Fe, and P. U-zone sebum showed significant positive correlations with serum levels of total cholesterol and triglycerides. From these findings, skin health status appears to be affected by both nutrient intake and body composition. Therefore, having a proper balance between dietary intake and body composition may influence skin health status in females with sensitive skin.
