Abstract

Oxygen therapy for healthy or inflamed but intact skin involves placing an oxygen-generating dressing onto the skin to be treated, the oxygen-generating bandage being a one-time use dressing capable of generating oxygen for only a short period of time, not to exceed about 4 hours.

Claims (16)

1. A method for improving the health or appearance of intact skin, comprising:

topically applying to a region of intact skin an admixture of a first gel containing a peroxide decomposition catalyst which catalyzes decomposition of peroxide to generate oxygen and a second gel containing a peroxide, said admixture capable of only one time use, and in which 80% or more of the peroxide is decomposed into oxygen, wherein oxygen is delivered over a period of about 2 to 4 hours.

2. The method of claim 1 , wherein the admixture contains at least one cosmetically acceptable humectant, emollient, or softening agent.

3. The method of claim 1 , wherein the intact skin comprises one or more of inflamed skin, wrinkled skin, hypoxic skin, and dry skin.

4. The method of claim 1 , wherein the intact skin is characterized by having wrinkles.

5. The method of claim 1 , wherein the intact skin is characterized by the presence of boils or pimples.

6. The method of claim 1 , wherein the skin is characterized by having rosacea.

7. The method of claim 1 , wherein oxygen generated by decomposition of peroxide in the admixture is absorbed transcutaneously through the outer epithelium of the intact skin into deeper dermal and subcutaneous layers.

8. The method of claim 1 , wherein the second gel contains hydrogen peroxide in an amount of less than 6% by weight.

9. The method of claim 1 , wherein the second gel contains hydrogen peroxide in an amount of from 0.5 weight percent to 6 weight percent.

10. A topical gel suitable for use in the method of claim 1 , wherein the topical gel comprises a first gel containing a peroxide decomposition catalyst which catalyzes decomposition of peroxide to generate oxygen and a second gel containing peroxide, the topical gel capable of only one time use, and the first and second gels capable of being admixed prior to topical application, and generating oxygen by peroxide decomposition upon mixing, wherein the topical gel delivers oxygen to a region of intact skin over a period of about 2 to 4 hours.

11. The topical gel of claim 10 , further containing at least one cosmetically acceptable humectant, emollient, or softening agent.

12. The topical gel of claim 10 , wherein the peroxide comprises hydrogen peroxide.

13. The topical gel of claim 10 , which is in the form of a cream or lotion.

14. The topical gel of claim 10 , wherein the second gel contains hydrogen peroxide in an amount of less than 6% by weight.

15. The topical gel of claim 10 , wherein the second gel contains hydrogen peroxide in an amount of from 0.5 weight percent to 6 weight percent.
