A Study of Effect of Skin Care Using Constitution-based Cosmetics

This study has compared photo aging, skin tone, evenness and sebum levels between experimental and control groups after identifying skin type based on the eight constitutions medical approach using a skin analyzer (ECOSKIN) and providing facial skin care using customized, constitution-based cosmetics. The photo aging, skin tone, evenness and sebum levels of facial skin by Colonotonia Pulmotonia, Hepatonia, and Pancreotonia have been measured and compared for 50 college-age women. The eight constitutions have been classified in accordance with the Eight-Constitution Medicine-32 (ECM-32) of Kyung Hee University. The photo aging, skin tone, evenness and sebum levels were measured using ECOSKIN. According to analysis of the effect of constitution-based cosmetics on photo aging, the photo-aging index increased (left: t=-5,811, p<.001 / right: t=-5,241, p<.001). In addition, there was an increase in skin tone index (left: t=-6,226, p<.001 / right: t=-5,313, p<.001). Both evenness (left: t=-7,563, p<.001 / right: t=-8,288, p<.001) and sebum levels (left: t=-12,164, p<.001 / right: t=-10,843, p<.001) have increased as well. This shows that constitution-based cosmetics are effective in skin care for the experimental group. Further scientific study is needed on cosmetics from the perspective of constitution-based skin cosmetology to investigate skin changes by age.
