Abstract

A method for treating a person's skin is disclosed. The method includes topically applying to the skin a composition comprising from 0.001% to 20% by weight of an aqueous, alcoholic, or aqueous-alcoholic extract from a plant extract.

First claim

The invention claimed is:

1. A method for treating loose and/or sagging skin in a person's skin in need thereof, the method comprising topically applying to loose and/or sagging skin a composition comprising:
an effective amount of a Syzygium cumini extract;
jojoba oil;
a wax; and
a preservative,
wherein the Syzygium cumini extract is an aqueous, alcoholic, or aqueous-alcoholic extract from Syzygium cumini , and
wherein the effective amount of the aqueous, alcoholic, or aqueous-alcoholic Syzygium cumini extract reduces matrix metalloproteinase-1 (MMP-1) activity in the skin and treats loose and/or sagging skin.

2. The method of claim 1 , wherein the skin in need thereof comprises a fine line or wrinkle.

3. The method of claim 1 , wherein the composition increases the firmness of the skin.

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

5. The method of claim 4 , wherein the composition is an oil-in-water emulsion.

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

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

8. The method of claim 1 , wherein the composition is a gel.

9. The method of claim 1 , wherein the composition is anhydrous.

10. The method of claim 1 , wherein the aqueous, alcoholic, or aqueous-alcoholic Syzygium cumini extract reduces oxidation in the skin.

11. The method of claim 1 , wherein the composition comprises 0.001% to 20%, by weight, of the aqueous, alcoholic, or aqueous-alcoholic Syzygium cumini extract.

12. The method of claim 11 , wherein the composition comprises 0.001% to 5%, by weight, of the aqueous, alcoholic, or aqueous-alcoholic Syzygium cumini extract.

13. The method of claim 1 , wherein the composition further comprises:
water;
a chelating agent;
an additional moisturizing agent;
and
a thickening agent.

14. The method of claim 1 , wherein the skin in need thereof is dry skin, and the composition moisturizes the skin.

15. The method of claim 14 , wherein the composition further comprises avocado ( Persea gratissima ) oil.

16. A method of treating loose and/or sagging skin in a person's skin in need thereof, the method comprising topically applying to loose and/or sagging skin a composition comprising:
a Syzygium cumini extract;
avocado ( Persea gratissima ) oil;
water;
shea butter;
stearyl alcohol;
behenyl alcohol;
glyceryl stearate;
glycerin;
lecithin or hydrogenated lecithin; and
sodium hyaluronate,
wherein the Syzygium cumini extract is an aqueous, alcoholic, or aqueous-alcoholic extract from Syzygium cumini , and
wherein the aqueous, alcoholic, or aqueous-alcoholic Syzygium cumini extract reduces matrix metalloproteinase-1 (MMP-1) activity in the skin and treats loose and/or sagging skin.

17. The method of claim 1 , wherein the water is present in an amount from 35-80% by weight.

18. The method of claim 1 , wherein the aqueous, alcoholic, or aqueous-alcoholic Syzygium cumini extract is a lyophilized extract in powdered form.

19. The method of claim 1 , wherein the aqueous, alcoholic, or aqueous-alcoholic Syzygium cumini extract is from the whole plant of Syzygium cumini.

20. The method of claim 1 , wherein the aqueous, alcoholic, or aqueous-alcoholic Syzygium cumini extract is from the fruit of Syzygium cumini.

21. The method of claim 1 , wherein the Syzygium cumini extract is an alcoholic extract and the alcoholic extract is an ethanolic extract.

22. The method of claim 1 , wherein the Syzygium cumini extract is an aqueous-alcoholic extract and the aqueous-alcoholic extract is and aqueous-ethanolic extract.

23. The method of claim 1 , wherein the composition further comprises:
cetyl palmitate;
green tea extract; and
methylparaben.

24. The method of claim 1 , wherein the composition further comprises:
water;
glycerin;
shea butter;
coconut oil;
beeswax;
sunflower seed oil
phenoxyethanol;
dimethicone;
carbomer; and
vitamin E.

25. The method of claim 1 , wherein the wax comprises beeswax.

26. The method of claim 1 , wherein the aqueous, alcoholic, or aqueous-alcoholic Syzygium cumini extract is a powdered extract.
