Cosmetic composition comprising a combination of at least one oligosaccharide and / or polysaccharide combined with mannose monosaccharide, and its use in maintaining the balance of skin bacterial flora.

Abstract

One objective is to provide a novel component that is active on the microbial skin flora, particularly by protecting the symbiotic flora, and that enables the maintenance and / or restoration of the balance of bacterial flora in the skin and / or mucous membranes. [Solution] The present invention relates to a cosmetic composition for topical application, comprising in a physiologically acceptable medium: - at least one oligosaccharide and / or polysaccharide selected from the group consisting of inulin, fructooligosaccharides, glucooligosaccharides, soybean-derived oligosaccharides, pyrodextrin, isomaltoligosaccharides, xylooligosaccharides, transgalactooligosaccharides and mixtures thereof; and - at least one mannose monosaccharide. The present invention also relates to a method of cosmetic treatment for the care of skin and / or mucous membranes, which includes the application of the composition in particular to skin and / or mucous membranes that have been subjected to external attacks, and to the cosmetic use thereof.
