Abstract
A method for preparing silicone elastomers containing hydrophilic skin actives with excellent characteristics is described. The elastomer shows enhanced efficacy with respect to the skin actives compared to skin care compositions formulated with individual elastomer and active components. Skin care compositions containing the inventive silicone elastomers and methods of skin treatment are also described.
