Abstract

Disclosed are composition and methods for treating skin whereby a cosmetic composition is applied to a target area of skin. The cosmetic composition comprises an effective amount of a skin active agent. A barrier patch is also provided and has a backing layer and a pressure sensitive adhesive. The barrier patch has an adhesive release force of about 50 gms to about 400 gms; a WVTR from about 1 g/m2/24 h to about 500 g/m2/24 h; and a flexibility from about 8 grams to about 40 grams.

First claim

What is claimed is:

1. 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/m 2 /24 h to about 20 g/m 2 /24 h and a flexibility of about 10 g to about 25 g.

2. The method of claim 1 wherein the barrier patch is water impermeable.

3. The method of claim 1 wherein the pressure sensitive adhesive provides an adhesive release force from about 100 g to about 200 g.

4. The method of claim 1 wherein the barrier patch is free of an effective amount of a skin active agent.

5. The method of claim 1 wherein the barrier patch completely covers the cosmetic composition.

6. The method of claim 1 wherein the cosmetic composition and barrier patch remain in contact with the target area of skin for a period of time from about 4 hours to about 24 hours.

7. The method of claim 6 wherein the cosmetic composition and barrier patch remain in contact with the target area of skin for a period of time from about 5 hours to about 10 hours.

8. The method of claim 1 wherein the barrier patch is adjusted to provide a hydration value from about 35 to about 120.

9. The method of claim 1 further comprising step d) repeating steps a) to b) daily from about 2 weeks to about 12 weeks.

10. The method of claim 1 wherein the target area of the skin comprises from about 1 cm 2 to about 50 cm 2 .

11. The method of claim 10 wherein the target area of the skin comprises from about 5 cm 2 to about 15 cm 2 .

12. The method of claim 1 wherein the cosmetic composition comprises from about 0.01% to about 10% by weight of vitamin B.

13. The method of claim 12 wherein the cosmetic composition further comprises niacinamide, glycerine, tocopherol acetate, d-panthenol, or combinations thereof.

14. The method of claim 1 wherein the skin active agent comprises from about 0.01% to about 10% of a skin active agent selected from the group consisting of vitamin E, vitamin A, palmitoyl-lysine-threonine, palmitoyl-lysine-threonine-threonine-lysine-serine, N-undecyl-10-enoyl-L-phenylalanine, retinyl propionate, N-acetyl glucosamine, vitamin C, tretinoin, salicylic acid, benzoic acid, benzoyl peroxide, and combinations thereof.

15. The method of claim 1 wherein the target area of skin is the facial skin surface.

16. The method of claim 1 wherein the WVTR is from about 2 g/m 2 /24 h to about 20 g/m 2 /24 h.

17. The method of claim 1 wherein the cosmetic composition is an oil in water emulsion.

18. The method of claim 1 wherein the barrier patch is essentially free of a non-woven material.

19. The method of claim 1 , wherein the release layer is paper coated with polyethylene and silicone.
