Abstract:
Optically-activated particles for use in cosmetic preparations to reduce the visual perception of skin imperfections, comprising:a) a plurality of substrate particles selected from the group consisting of nylons, acrylics, polyesters, other plastic polymers, natural materials, regenerated cellulose, metals and minerals; wherein said substrate particles have an index of refraction greater than 1.0; b) an optical brightener chemically bonded to each of said plurality of substrate particles to form integral units in the form of optically-activated particles for diffusing and emitting light to reduce the visual perception of skin imperfections by bending the image of the skin imperfections away from the viewer's visual axis; and c) each of said optically-activated particles being encapsulated with a UV transparent coating to increase the diffusion of light to further reduce the visual perception of the skin imperfections.
