Abstract

A personal-care composition in the form of an oil-in-water emulsion is disclosed that provides improved skin feel and effective wrinkle-filling. The personal-care composition comprises a silicone elastomer; a silicone fluid; a combination of particulate materials; a polymeric thickener; and water. The combination comprises at least three particulate materials which pack together in order to fill wrinkles.
