Abstract

Disclosed are compositions and methods that can be used to improve the skin's visual appearance. In certain aspects, the compositions disclosed herein can include, for example, a combination of ingredients to exfoliate, reduce or eliminate irritation from exfoliation, renew the skin, increase skin radiance, sooth the skin, or increase skin smoothness. This combination of ingredients can be included in a wide-range of product formulations (e.g., serums, eye creams, toners, gels, masks, peels, etc.).

First claim

The invention claimed is:

1. A method of counteracting skin irritation caused by an exfoliant, the method comprising topically applying an effective amount of a skin exfoliation composition to skin in need thereof,
wherein the composition comprises:
25 wt. % to 80 wt. % water,
2 wt. % to 20 wt. % of an alpha hydroxy acid to exfoliate the skin,
0.1 wt. % to 1.5 wt. % of 4-tert-butylcyclohexanol,
0.001 wt. % to 0.1 wt. % of an aqueous extract of plankton comprising an exopolysaccharide synthesized by Vibro alginolyticus,
0.001 wt. % to 0.1% wt. % of an aqueous extract of Phragmites communis,
0.001 wt. % to 0.1 wt. % of an aqueous extract of Poria cocos , and
0.0001 wt. % to 0.01 wt. % of an aqueous extract of Cucurbita pepo (pumpkin) seed.

2. The method of claim 1 , wherein the composition further comprises:
triethanolamine;
glycerin;
butylene glycol;
sea water;
cetearyl alcohol;
arachidyl alcohol;
sorbitan isostearate;
dicaprylyl carbonate;
biosaccharide gum-1; and
behenyl alcohol.

3. The method of claim 1 , wherein the skin is facial skin.

4. The method of claim 3 , wherein the composition remains on the facial skin for up to 15 minutes and is then removed from the skin.

5. The method of claim 4 , wherein the composition is applied to a fine line or wrinkle.

6. The method of claim 4 , wherein the composition is applied to skin having an uneven skin tone.
