The facial skin condition expresses physical healthy as well as is considered one of important factors for attractiveness. Especially, most people prefer shiny skin. So various cosmetics has been manufactured for expression of shiny skin. However, shiny skin is subjectively evaluated, and difficult to evaluate clear shininess using the existing method in oily skin. Moreover, there is no clear classification criteria between shininess and glossiness, which is assessed negatively in the skin. So there has not been a reference value by mechanical measurement to define and classify shiny skin from greasy skin. In this study, we measured skin biophysical parameters (gloss, hydration, translucency and sebum) and facial images which are selected by volunteers using sensory evaluation. According to the measurement results, the values of gloss, sebum, and translucency were similar in both shiny and greasy skin; the values of sebum and gloss increased, whereas those of translucency decreased. However only skin moisture values statistically increased in shiny skin. In conclusion, we propose objective assessment criteria for classifying shiny and greasy skin using device measurement and quantitative assessment.
