Abstract:
1. A method of reducing light reflection from a biological surface by applying to said biological surface a layer of a composition comprising: (a) a plurality of hydrophobic fumed silica nanoparticles, the fumed silica nanoparticles having a particle size less than the wavelength of visible light; (b) a combination of iron oxide and carbon black pigments; and (c) a cosmetically or pharmaceutically acceptable carrier comprising one or more of a film former or wax; wherein the weight ratio of hydrophobic fumed silica nanoparticles to pigment is between about 1.0:1.0 and about 1.0:10.0; and wherein said layer of said composition provides a dry film having an L* value of 25 or less.
