Abstract

|
Aged skin is characterized by a number of different signs, such as, wrinkles, dull skin, low skin elasticity, etc. Cosmetics are generally used to reduce such aging signs for healthy and beautiful skin. In order to properly express the functions of cosmetic products, objective evaluation methods must be established. Korea Food & Drug Administration regulates such laws regarding the efficacy of functional cosmetics (anti-wrinkle, skin whitening, SPF) and their proper expressions in advertisement. Recently, non-invasive imaging techniques have drawn great attention from researchers developing more objective evaluating methods. These methods include, in vivo confocal microscopy, multi-photon tomography, OCT, etc. Utilizing these advanced tools, our goal is to establish a more objective method for evaluating both the skin surface and inner skin.
