Abstract

A method of topically applying to skin a composition comprising a water soluble Phoenix dactylifera seed extract, an essential oil from the leaves of tea tree, an aqueous Myrothamnus flabellifolia leaf and stem extract, and a saccharide isomerate comprising an exopolysaccharide of Vibrio alginolyticus is disclosed.

Claims (34)

1. A method of treating a fine line or wrinkle on the skin under a human's eye and/or moisturizing the skin under a human's eye, the method comprising topically applying to the fine line or wrinkle on the skin under the human's eye a composition comprising:

a Melaleuca alternifolia leaf extract;

a Myrothamnus flabellifolia leaf and stem extract;

a saccharide isomerate;

caprylic/capric triglyceride;

glycerin;

xanthan gum;

hyaluronic acid; and

sodium hyaluronate;

wherein the fine line or wrinkle on the skin under the human's eye is reduced and/or the moisture of the skin under the human's eye is increased.

2. The method of claim 1 , wherein the composition reduces oxidation in the skin of the human.

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

4. The method of claim 3 , wherein the emulsion is an oil-in-water emulsion.

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

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

7. The method of claim 1 , wherein the composition is applied to dry skin under the human's eye, and the composition moisturizes the dry skin under the human's eye.

8. The method of claim 1 , wherein the Melaleuca alternifolia leaf extract comprises an essential oil.

9. The method of claim 1 , wherein the Myrothamnus flabellifolia leaf and stem extract reduces tumor necrosis factor alpha (TNF-α) production and/or inhibits nitric oxide synthase in the skin of the human.

10. The method of claim 1 , wherein the Myrothamnus flabellifolia leaf and stem extract is an aqueous extract.

11. The method of claim 1 , wherein the saccharide isomerate reduces tumor necrosis factor alpha (TNF-α) production and/or inhibits nitric oxide synthase in the skin of the human.

12. The method of claim 1 , wherein the saccharide isomerate comprises an exopolysaccharide of Vibrio alginolyticus.

13. The method of claim 1 , wherein the saccharide isomerate is an aqueous extract of Vibrio alginolyticus.

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

0.0001 wt. % to 10 wt. % of the Melaleuca alternifolia leaf extract;

0.0001 wt. % to 10 wt. % of the Myrothamnus flabellifolia leaf and stem extract; and

0.0001 wt. % to 10 wt. % of the saccharide isomerate.

15. The method of claim 1 , wherein the composition comprises at least 50 wt. % water.

16. The method of claim 1 , wherein the composition further comprises a moisturizing agent.

17. The method of claim 1 , wherein the composition further comprises an emulsifier or surfactant.

18. The method of claim 1 , wherein the composition further comprises a ultraviolet light absorption or reflection agent.

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

ascorbic acid;

hydrogenated vegetable oil; and

citric acid.
