Abstract

A method for treating skin of a person is disclosed. The method can include topically applying to the skin of the person a composition comprising an effective amount of an aqueous, alcoholic, or aqueous-alcoholic extract from Chamaecrista mimosoides , wherein the composition reduces tyrosinase activity in the skin, increases antioxidant activity in the skin, and/or increases skin moisture content.

Claims (63)

1. A method for treating skin of a person in need thereof, the method comprising topically applying to the skin of the person a composition comprising an effective amount of an aqueous, alcoholic, or aqueous-alcoholic extract from Chamaecrista mimosoides , alcohol, butylene glycol, glycerin, kojic acid, tocopherol, disodium EDTA, hydrogenated lecithin, and succinic acid,

wherein the skin comprises hyperpigmented or unevenly colored skin, and

wherein the composition reduces tyrosinase activity in the skin, increases antioxidant activity in the skin, and/or increases skin moisture content.

2. The method of claim 1 , wherein the composition is applied to hyperpigmented skin.

3. The method of claim 2 , wherein the hyperpigmented skin is melasmic skin.

4. The method of claim 2 , wherein the hyperpigmented skin is a sunspot, age spot, or freckle.

5. The method of claim 2 , wherein the composition lightens skin.

6. The method of claim 1 , wherein the composition is applied to unevenly colored skin.

7. The method of claim 6 , wherein the unevenly colored skin is melasmic skin.

8. The method of claim 6 , wherein the unevenly colored skin is a sunspot, age spot, or freckle.

9. The method of claim 6 , wherein the composition evens skin tone.

10. The method of claim 1 , wherein the composition reduces tyrosinase activity.

11. The method of claim 1 , wherein the composition reduces oxidative damage to skin.

12. The method of claim 1 , wherein the composition is applied to dehydrated skin.

13. The method of claim 12 , wherein the dehydrated is dry skin.

14. The method of claim 12 , wherein the composition increases skin moisture content.

15. The method of claim 1 , wherein the composition is applied to sagging or loose skin.

16. The method of claim 15 , wherein the composition increases skin elasticity or firmness.

17. The method of claim 1 , wherein the composition is applied to a fine line or wrinkle.

18. The method of claim 1 , wherein the composition is an emulsion.

19. The method of claim 18 , wherein the composition is an oil-in-water emulsion.

20. The method of claim 1 , wherein the composition is a cream or a lotion.

21. The method of claim 1 , wherein the composition is a solution.

22. The method of claim 1 , wherein the composition comprises 0.001% to 5%, by weight, of the extract.

23. The method of claim 1 , wherein the composition further comprises:

(a) algin;

(b) dimethicone;

(c) glycereth-26;

(d) behenyl alcohol;

(e) mineral oil;

(f) polysorbate 80;

(g) sorbitan palmitate;

(h) linalool; and

(i) titanium dioxide.

24. The method of claim 1 , wherein the composition further comprises:

(a) ascorbic acid;

(b) honeysuckle extract;

(c) grape seed extract;

(d) cholesterol;

(e) citric acid;

(f) gellan gum; and

(g) lecithin.

25. The method of claim 1 , wherein the composition further comprises:

(a) algae extract;

(b) honeysuckle extract;

(c) cholesterol;

(d) gellan gum;

(e) lecithin;

(f) methylparaben; and

(g) ethylparaben.

26. The method of claim 1 , where the composition further comprises:

(a) water;

(b) a chelating agent;

(c) a moisturizing agent;

(d) a preservative; and/or

(e) a thickening agent.

27. The method of claim 1 , wherein the extract is in liquid form and comprises the extracting solvent.

28. The method of claim 1 , wherein the extract is a lyophilized extract in powdered form.

29. The method of claim 1 , wherein the extract is from the whole plant of Chamaecrista mimosoides.

30. The method of claim 1 , wherein the extract is an alcoholic extract.

31. The method of claim 30 , wherein the alcoholic extract is an ethanolic extract.

32. The method of claim 1 , wherein the composition comprises 0.5% to 1%, by weight, of the extract.

33. The method of claim 1 , wherein the composition comprises 0.8% to 1.5%, by weight, of the extract.
