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/m 2 /24 h to about 500 g/m 2 /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 to a target area of the skin, comprising an effective amount of a skin active agent; b. applying a barrier patch to the target area of skin, the barrier patch comprising:
a backing layer having a first surface;
a pressure sensitive adhesive in contact with the first surface;
adjusting the properties of the barrier patch to have:
an adhesive release force of about 50 gms to about 400 gms;
a WVTR of about 1 g/m 2 /24 h to about 500 g/m 2 /24 h;
a flexibility of about 8 grams to about 40 grams.

2 . The method of claim I wherein the WVTR is from about 1 g/m 2 /24 h to about 250 g/m 2 /24 h.

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

4 . The method of claim 1 wherein the flexibility is from about 10 grams to about 25 grams.

5 . The method of claim 1 wherein the transparency threshold for the barrier patch is no greater than about 10 point.

6 . The method of claim 5 wherein the transparency threshold for the barrier patch is no greater than about 4 point.

7 . The method of claim 1 wherein the pressure sensitive adhesive provides a adhesive release force from about 100 grams to about 200 grams.

8 . The method of claim 7 wherein the pressure sensitive adhesive is selected from the group consisting of acrylic and methacrylic ester homo-or copolymers, butyl rubber based systems, silicones, urethanes, vinyl esters and amides, olefin copolymer materials, and combinations thereof.

9 . The method of claim 1 wherein the barrier patch is substantially free of skin active agent.

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

11 . 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.

12 . The method of claim 11 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.

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

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

15 . The method of claim 1 wherein the barrier patch has a thickness of about 1 mils to about 35 mils.

16 . The method of claim 15 wherein the barrier patch has a thickness of about 3 mils to about 15 mils.

17 . The method of claim 16 wherein the barrier layer has a thickness of about 2 mils to about 15 mils and the adhesive has a thickness of about 1 mils to about 5 mils.

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

19 . The method of claim 18 wherein the target area of the skin comprises from about 5 cm 2 to about 15 cm 2 .

20 . The method of claim 1 wherein the barrier patch further comprises a release layer on the surface of the pressure sensitive adhesive and opposite the backing layer.

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

22 . The method of claim 21 wherein the cosmetic composition further comprises niacinamide, glycerine, tocopherol acetate, D-panthenol,and combinations thereof.

23 . 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, tretinoin, and combinations thereof.

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

25 . The method of claim 1 wherein the WVTR is from about 1 g/m 2 /24 h to about 180 g/m 2 /24 h.

26 . The method of claim 25 wherein the WVTR is from about 2 g/m 2 /24 h to about 20 g/m 2 /24 h.

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

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

29 . A method of treating skin comprising:
a. applying a cosmetic composition to a target area of the skin, comprising an oil in water emulsion with an effective amount of a skin active agent that is provided as separate component from a barrier patch; b. applying the barrier patch comprising:
a backing layer having a first surface;
a pressure sensitive adhesive in contact with the first surface;
adjusting the properties of the barrier patch to have:
an adhesive release of about 75 gms to about 350 gms;
a WVTR of about 1 g/m 2 /24 h to about 180 g/m 2 /24 h;
a flexibility of about 8 grams to about 25 grams.

30 . A method of treating skin comprising:
a. applying a cosmetic composition to a target area of the skin, comprising an effective amount of a skin active agent that is provided as separate component from a barrier patch; b. applying the barrier patch comprising:
a backing layer having a first surface;
a pressure sensitive adhesive in contact with the first surface;
adjusting the properties of the barrier patch to have:
an adhesive release force of about 50 gms to about 400 gms;
a WVTR of about 1 g/m 2 /24 h to about 500 g/m 2 /24 h;
a flexibility of about 8 grams to about 40 grams; and

adjusting the barrier patch to provide a hydration value from about 35 to about 120.

31 . The method of claim 30 wherein the WVTR is from about 1 g/m 2 /24 h to about 180 g/m 2 /24 h.

32 . The method of claim 31 wherein the adhesive release force is about 75 gms to about 350 gms and the flexibility is about 8 grams to about 25 grams.
