Claims19
A method of treating skin comprising:
- a) applying a cosmetic composition comprising an effective amount of a skin active agent to a target area of skin, and thereafter;
- b) applying a transparent barrier patch to the target area of skin, the barrier patch consisting of 3 layers and having a thickness of about 3 mils to about 15 mils, wherein
- (i) a first layer of the barrier patch is a polyethylene film backing layer comprising a first surface that is free of an effective amount of a skin active agent,
- (ii) a second layer of the barrier patch is a pressure sensitive acrylate adhesive layer in contact with the first surface of the backing layer, and
- (iii) a third layer of the barrier patch is a release layer comprising a film that covers a surface of the pressure sensitive adhesive opposite the backing layer;
- and
- c) adjusting the barrier patch to provide an adhesive release force of about 50 g to about 400 g, a Water Vapor Transmission Rate (WVTR) of about 1 g/m2/24 h to about 20 g/m2/24 h and a flexibility of about 10 g to about 25 g.
