Abstract

The present invention relates to a composition comprising, in a cosmetically acceptable medium: a) composite particles with a mean size of greater than 0.1 μm, containing a matrix comprising i) at least one organic material and/or at least one mineral material and ii) at least titanium dioxide; and b) hydrophobic silica aerogel particles. The invention also relates to a cosmetic process for caring for and/or making up human keratin materials, especially bodily or facial skin or the hair, comprising at least the application, to the surface of the keratin material, of a composition as defined previously. The invention also relates to a non-therapeutic cosmetic process for limiting the darkening of the skin and/or improving the color and/or uniformity of the complexion, comprising the application, to the surface of the keratin material, of a composition as defined previously. The invention also relates to a non-therapeutic cosmetic process for preventing and/or treating the signs of ageing of a keratin material, comprising the application, to the surface of the keratin material, of a composition as defined previously.
