Outline of Final Research Achievements

Foundation, which is one of the basic cosmetics, plays an important role in making skin up. The purpose of this study is to set assessment standards in evaluating foundation performances, which has been made by visual assessment so far. In this study, we have developed a system for measuring 2-dimentional optical properties distribution of human skin and we verified the usefulness of the system. In addition, assuming human skin has uniform optical properties, we have measured optical properties of skin for over 200 people. Base on the measured results, an artificial skin with optical properties of real human skin has fabricated. Furthermore, to develop an assessment method, we developed a measurement instrument for understanding optical characteristics of foundation layer, such as reflection and/or transmission characteristics.
