Ronasphere^® LDP is a functional filler that has been developed in order to provide optical reduction of fine lines and wrinkles. This product consists of silica spheres coated with titanium dioxide and iron oxide. The coating results in a product with a refractive index close to that of the skin, therefore the filler is practically invisible when applied to the skin.

The light diffusing properties of Ronasphere^® LDP allow the formulation of skin care and decorative cosmetics.
