A Relevant Study Correlating the Actual Observed Physiological Properties and a Cosmetic-User's Subjective Evaluations of Skin

The purpose of the present study is to get an accurate grasp of female's self assessments, examine which skin problems have good/bad correlations with objective evaluations and analyze the reasons for the ones that do not match.In this study, we collected 174 healthy Japanese female's evaluations on their own facial skin through the face to face interviews and questionnaires. Then the results were compared with physiological evaluations, which include clinical observations and measurements for the water content, skin surface lipids, skin elasticity, skin microstructure, etc.Oiliness and age related condition (pigmentation, wrincles, sagging) show relatively good correlation while dryness does not. This incongruity between the subjective evaluation and the actual skin codition often leads to an inadequate selection of cosmetics and improper skin care which may induce skin troubles.
