Novel Skin Evaluation Methods Using Cutting-edge Optical Techniques

Abstract

The acquisition of objective skin information by analytical techniques is essential for evaluation of the effects of cosmetics and pharmaceuticals to the skin. In addition, analytical approaches that target not only the skin surface, but also those that specifically evaluate skin layer features and skin constituents are long-awaited. The progress of non-invasive optical technologies in recent years enables us acquisition of the skin structural information at a molecular level as well as the evaluation of skin physical properties. In this article, we present our novel skin evaluation methods developed using optical techniques.
