Abstract
A cosmetic composition contains a dispersion, in a fatty binder, of a particulate filler composed of solid particles of at least one material compatible with application to the skin. The particulate filler contains at least 50 wt. %, or at least 75 vol. % relative to the total particulate filler, of spherical or spheroidal particles 0.5 to 50 .mu. in size. The particulate filler has an oil uptake such that its concentration by volume C*, when the volume of binder is equal to that of the oil uptake (measured on the nonvolatile fraction of the binder), is between 3 and 90%. The concentration by volume of the particulate filler in the dispersion, measured on the nonvolatile fraction of the binder, namely without taking into account any volatile oils that may be present in the fatty binder, is at least equal to C* and preferably greater than C*. This composition allows skin defects (color differences and micro reliefs) to be blurred while leaving a translucent layer on said skin.
