Cosmetic compositions comprising marine plants
The present invention relates to a cosmetic active ingredient for improving the appearance of the skin beneath the eyes. More particularly, the present invention relates to a cosmetic active ingredient comprising an extract of the marine algae, Fucus vesiculosus . The present invention also relates to topical cosmetic compositions comprising as an active component an extract of the marine algae, Fucus vesiculosus , alone or in combination with additional cosmetic active ingredients, to reduce the appearance of dark circles in skin beneath the eye.
1. A method of increasing heme oxygenase type 1 activity so as to reduce the appearance of dark circles in skin beneath the eye(s) of a subject in need thereof, the method comprising applying to the skin of said subject a safe and effective amount of a topical composition comprising an extract of Fucus vesiculosus , wherein the extract is present in an amount from about 0.1 percent to about 10 percent by weight based on total weight of the composition, and wherein the extract is formed by adding a coarse ground biomass of Fucus vesiculosus to at least one of deionized water or a polyethylene glycol (PEG) solution for a suitable period of time.
2. A method for catalyzing degradation of heme so as to reduce the appearance of dark circles in skin beneath the eye(s) of a subject in need thereof, the method comprising applying to the skin of said subject a safe and effective amount of a topical composition comprising an extract of Fucus vesiculosus , wherein the extract is present in an amount from about 0.1 percent to about 10 percent by weight based on total weight of the topical composition, and wherein the extract is formed by adding a coarse ground biomass of Fucus vesiculosus to water and/or polyethylene glycol (PEG) for a suitable period of time.
3. The method of claim 1 , wherein the extract is an aqueous extract.
4. The method of claim 2 , wherein the extract is present in an amount of about 0.5 percent to about 5 percent by weight, based on the total weight of the topical composition.
5. The method of claim 4 , wherein the topical composition is a cream, gel, or lotion product.
6. The method of claim 2 , wherein the extract is present in an amount of about 2 percent by weight, based on the total weight of the topical composition.
7. The method of claim 1 , wherein the extract of Fucus vesiculosus is formed by adding the coarse ground biomass of Fucus vesiculosus to the deionized water.
8. The method of claim 1 , wherein the extract of Fucus vesiculosus is formed by adding the coarse ground biomass of Fucus vesiculosus to the PEG solution.
9. The method of claim 2 , wherein the extract of Fucus vesiculosus is formed by adding the coarse ground biomass of Fucus vesiculosus to the water.
10. The method of claim 2 , wherein the extract of Fucus vesiculosus is formed by adding the coarse ground biomass of Fucus vesiculosus to the PEG solution.
