The present invention relates to a composition, in particular comprising a physiologically acceptable medium, in particular for coating keratin materials, more particularly for making up and/or caring for keratin materials, comprising: a) at least one soft-focus filler, and b) at least one composite pigment comprising at least one non-spherical aluminium oxide, at least one metal oxide and at least one surface-treatment agent. According to another subject of the invention, the present invention relates more particularly to a composition as previously defined, in emulsion form. The present invention also relates to a composition comprising: a) at least one soft-focus filler, other than boron nitride and b) at least one composite pigment comprising at least one non-spherical aluminium oxide, at least one metal oxide and at least one surface-treatment agent, and c) boron nitride particles. The invention also relates to a process for coating keratin materials, more particularly for making up and/or caring for keratin materials, such as the skin, characterized in that it comprises the application to the keratin materials of a composition as previously defined.
