Abstract

The present invention relates generally to compositions and methods of using the same such as, for example, methods of treating the skin of a subject using a composition as described herein. The composition may comprise a diluent, a solvent, a penetration enhancing agent, a skin brightening agent, a skin renewing agent, a thickening agent, an anti-irritant, a chelating agent, an active pharmaceutical ingredient (API), optionally a pH adjustment agent, and optionally a preservative. The composition may further comprise L-arginine and/or L-citrulline and/or esters and/or derivatives thereof.

First claim

That which is claimed is:

1. A topical composition comprising:
a diluent, wherein the diluent is water and water is present in an amount of about 60% to about 95% by weight of the topical composition:
a solvent, wherein the solvent comprises an alcohol:
a penetration enhancing agent, wherein the penetration enhancing agent comprises a glycol ether;
a skin brightening agent, wherein the skin brightening agent comprises a peptide comprising the amino acid sequence of SEQ ID NO:1:
a skin renewal agent, wherein the skin renewal agent comprises a peptide;
a thickening agent, wherein the thickening agent comprises a polyacrylate polymer;
an anti-irritant;
a chelating agent;
an active pharmaceutical ingredient (API) selected from the group consisting of salicylic acid, a nitric oxide (NO)-releasing compound, and any combination thereof;
optionally a pH adjustment agent; and
optionally a preservative.

2. The topical composition of claim 1 , further comprising L-arginine, esters thereof, or derivatives thereof; L-citrulline, esters therefor or derivatives thereof; or any combination thereof.

3. The topical composition of claim 1 , wherein the water is present in an amount of about 70% to about 90% by weight of the topical composition.

4. The topical composition of claim 1 , wherein the alcohol is tert-butyl alcohol.

5. The topical composition of claim 1 , wherein the solvent is present in an amount of about 1% to about 20% by weight of the topical composition.

6. The topical composition of claim 1 , wherein the glycol ether is ethoxydiglycol.

7. The topical composition of claim 1 , wherein the penetration enhancing agent is present in an amount of about 1% to about 10% by weight of the topical composition.

8. The topical composition of claim 1 , wherein the skin brightening agent is present in an amount of about 0.1% to about 10% by weight of the topical composition.

9. The topical composition of claim 1 , wherein the skin renewal agent is present in an amount of about 0.1% to about 10% by weight of the topical composition.

10. The topical composition of claim 1 , wherein the thickening agent is present in an amount of about 0.1% to about 5% by weight of the topical composition.

11. The topical composition of claim 1 , wherein the anti-irritant is present in an amount of about 0.1% to about 10% by weight of the topical composition.

12. The topical composition of claim 1 , wherein the chelating agent is present in an amount of about 0.01% to about 2% by weight of the topical composition.

13. The topical composition of claim 1 , wherein the API is salicylic acid.

14. The topical composition of claim 1 , wherein the API is present in an amount of about 0.1% to about 10% by weight of the topical composition.

15. The topical composition of claim 1 , wherein the topical composition comprises the pH adjustment agent and the pH adjustment agent is present in an amount of about 0.01% to about 3% by weight of the topical composition.

16. The topical composition of claim 1 , wherein the topical composition comprises the preservative and the preservative is present in an amount of about 0.01% to about 3% by weight of the topical composition.

17. The topical composition of claim 1 , wherein the API is a NO-releasing compound.

18. A kit comprising the topical composition of claim 1 .

19. The kit of claim 18 , wherein a first container comprises one or more components of the topical composition and a second container comprises one or more of the same or different components of the topical composition, wherein the first container and second container comprise at least one component that is different or not present in the other container.
