A colorimetric measurement head, for determining the internal color of a non-opaque material, in particular the internal color of the human skin, includes an emitter which emits light, towards the material to be studied, and is separated by an opaque wall from a emitter which receives light which has penetrated into the material and which is reflected thereby. An external surface of the head, which is positioned at the material to be studied, and contacts this surface either by direct application against the surface, or with optical wetting. The light received by the detector comes from the interior of the material, whereas the light possibly reflected by the surface of the material or coming directly from the emitter cannot reach the detector because of the opaque separating wall.

Colorimetric measurement head and method for determining the internal

Use of a colloidal suspension based on inorganic fillers, which can be prepared by the sol-gel process, as a cosmetic composition for treating the skin, hair and/or nails for the purpose of forming, after evaporation of the liquid medium of the suspension, an inorganic film on the skin, hair and/or nails.
