Abstract

Disclosed are compositions and methods for their use that include a combination of escin, Ruscus aculeatus root extract, ammonium glycyrrhizate, Centella asiatica extract, hydrolyzed yeast protein, and Calendula officinalis flower extract.

Claims (30)

1. A method of treating oxidative damage in the skin of a human, the method comprising topically applying to the skin of the human in need thereof a composition comprising:

water;

butylene glycol;

panthenol;

glycerin; and

a therapeutically effective amount of:

escin; Ruscus aculeatus root extract; ammonium glycyrrhizate; Centella asiatica extract; hydrolyzed yeast protein; and Calendula officinalis flower extract,

wherein topical application of the composition to the skin of the human in need thereof effectively treats the skin of the human in need thereof.

2. The method of claim 1 , wherein the composition reduces the formation of reactive oxygen species in the skin of the human in need thereof.

3. The method of claim 2 , wherein the formation of reactive oxygen species is from ultra-violet radiation exposure to the skin of the human in need thereof.

4. The method of claim 2 , wherein formation of reactive oxygen species is from a chemical exposure to the skin of the human in need thereof.

5. The method of claim 1 , wherein the oxidative damaged skin further comprises a fine line.

6. The method of claim 1 , wherein the oxidative damaged skin further comprises a wrinkle.

7. The method of claim 1 , wherein the oxidative damaged skin further comprises erythemic skin.

8. The method of claim 1 , wherein the oxidative damaged skin further comprises inflamed skin.

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

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

11. The method of claim 1 , wherein the composition further comprises 80% to 90% by weight of water.

12. The method of claim 1 , wherein the therapeutically effective amounts of the components of the composition are:

0.0001% to 1% by weight of escin;

0.0001% to 1% by weight of Ruscus aculeatus root extract;

0.0001% to 1% by weight of ammonium glycyrrhizate;

0.0001% to 1% by weight of Centella asiatica extract;

0.0001% to 1% by weight of hydrolyzed yeast protein; and

0.0001% to 1% by weight of Calendula officinalis flower extract.

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

propylene glycol; diazolidinyl urea; PPG-5-ceteth-20; methylparaben; sodium citrate; disodium EDTA; buteth-3; propylparaben; citric acid; and sodium benzotriazolyl butylphenol sulfonate.

14. The method of claim 1 , wherein the composition further comprises: pentylene glycol; glycereth-26; propylene glycol; triethanolamine; acrylates/C 10-30 alkyl acrylate crosspolymer; diazolidinyl urea; hydroxy ethylcellulose; sodium polyacrylate; methylparaben; disodium EDTA; phenoxy ethanol; caprylyl glycol; and propylparaben.

15. The method of claim 1 , wherein the composition further comprises: pentylene glycol; polysilicone-11; hydroxyethyl acrylate/sodium acryloyldimethyl taurate copolymer; dimethicone; squalane; glyceryl undecylenate; silica; triethanolamine; polysorbate 60; acrylates/C 10-30 alkyl acrylate crosspolymer; hydroxypropyl cyclodextrin; and sorbitan isostearate.

16. The method of claim 1 , wherein the composition further comprises: pentylene glycol; glycereth-26; benzyl alcohol; triethanolamine; acrylates/C 10-30 alkyl acrylate crosspolymer; hydroxy ethylcellulose; sodium polyacrylate; disodium EDTA; hydroxypropyl cyclodextrin; phenoxy ethanol; and caprylyl glycol.
