A method of preparation of a cosmetic composition able to blur defects of the skin while leaving a translucent layer thereon, comprising forming 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, said particulate filler containing at least 50 wt. %, or at least 75 vol. % relative to the total particulate filler, of spherical or spheroidal particles with dimensions of 0.5 to 50.mu., said particulate filler having an oil uptake such that its volume concentration C*, when the binder volume is equal to that of the oil uptake (measured in the nonvolatile fraction of the binder), is between 3 and 90%, and the volume concentration of the particulate filler, in said dispersion, calculated without taking into account any volatile oils present in the fatty binder, is at least equal to C*.

Cosmetic composition able to blur skin defects while leaving a translucent layer on the skin, said composition comprising 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, said particulate filler containing 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, said particulate filler having 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 said dispersion, measured on a nonvoltile fraction of the binder, namely without taking into account any volatile oils that may be present in the fatty binder, being at least equal to C*, and wherein the nonvolatile portion of said fatty binder has a melting or softening point no higher than 37.degree. C.
