정상 피부와 과색소가 침착된 피부의 Melanin양과 Erythema양간의 상관성과 정량적 변화

Colors of human skin are a wide range and variety such as white, brown and black. Melanin and erythema play a important role for definition of skin color. The aim of the study is to assess the content and correlation between melanin and erythema in different body sites in skin. volunteers of males and females in twenties age group of korean were agreed with experiment and content of melanin and erythema on the face, back and abdomen of body were measured in range of 450-870nm by mexameter. The analysis of correlations was used by SPSS 11.0 program. In the result, the highest content of melanin was shown in abdomen of male (137.6~250.4AU) and female (112.2~224.0AU) group, but the highest erythema content of face appears in male (336.1~453.3AU). Melanin content of hyperpigmented skin is relative higher than erythema in compared with normal skin. Good correlation was observed not only in normal back skin of males and females (r=0.744, r=0.831) but also back and abdomen in hyperpigmented skin of males and females (r=0.826, r=0.974), in spite of very low correlation in face of males and females. And the level of melanin and erythema in different skins of twenties age group was shown relatively different values, and level of melanin was lower in face of females than males. So that melanin and erythema content revealed great individuality. In conclusion, primary data of melanin and erythema content in different body skins of korean could be collected. Cleansing and washing with cosmetics and/or soaps in face may be help depigmentation (alkali soluble eumelanin), and measurement of melanin content could be useful for hyperpigmentation parameter.
