Abstract
The present invention relates to a cosmetic composition comprising, in a physiologically acceptable aqueous medium: (a) at least 0.01% by weight based on the total weight of the composition, native chitosan having a molecular weight strictly greater than 3000 daltons, this quantity being strictly less than 15% by weight, (b) at least one alpha hydroxy acid; (c) from 3 to 50% at least one pigmentary coloring material with respect to the total weight of the composition, and (d) at least one polyol; wherein the weight ratio between polyol(s) and chitosan is between 0.1 and 6.
