Abstract
An anti-wrinkle skin treating composition comprises a pressure sensitive matrix patch having dissolved in the adhesive a mixture of antioxidants in the form of a Vitamins C ester and Vitamin E. Also preferably dissolved in the adhesive are glycerine and a polydiorganosiloxane adhesion-adjusting agent. Optionally dissolved in the adhesive is also one or more members selected from the group consisting of moisturizing agents, skin collagen synthesis promoting agents and exfoliating agents. When applied to a wrinkled skin area the composition acts to diminish fine wrinkles and improves the overall thickness, elasticity, firmness and smoothness of the skin. The modified adhesive properties of the patch are sufficient to maintain the patch in place on the skin for the recommended treatment period while allowing the patch to be readily removed without causing skin irritation or leaving adhesive residue on the skin.
