Optical Properties of Cosmetic Foundations

Abstract

For the development of cosmetic foundations that achieve beautiful skin appearances, control of their optical properties is critical. The control is achieved by mainly two approaches: synthesis of pigments that exhibit desired optical behaviors; fabrication of pigmented layers that exhibit desired optical behaviors. Based on these approaches, various techniques for the control of reflection, the most important optical properties, have been reported. In this paper, basic knowledge regarding reflection is firstly introduced. Then, prominent techniques for the reflection control of foundations are reviewed. In this review, previous studies that aimed the visually naturo-beautiful skin are mainly illustrated. Finally, technical problems on current optical control techniques are described.
