Abstract:
The present invention relates to a topical composition comprising at least one collagen protecting and/or collagen enhancing agent and a silica-titanium dioxide composite particle having a particle size Dv0 of greater 0.3 μm, a Dv100 of less than 35 μm and a Dv50 of 4.0 to 10 μm, wherein the silica-titanium dioxide composite particle consists of 20-45 wt.-% titanium dioxide particles having a particle size Dv50 of 100 to 300 nm embedded in a matrix of silica. Furthermore the invention relates to the use of such silica-titanium dioxide composite particles to ameliorate the sensory properties of a topical composition comprising collagen protecting agent and/or collagen enhancing agent as well as to reduce the short and long term eye contour puffiness, dark eye circles, crow's feet and fine lines.
