According to the invention, at least one agent for promoting the adhesion of the keratinocytes of the epidermal baseal layer to the dermo-epidermal junction, especially to the collagen IV of said junction, such as, in particular, a divalent metal salt or complex, preferably magnesium aspartate or magnesium chloride, is used, optionally in association with a stimulant of collagen IV synthesis and/or a stimulant of collagen VII synthesis. The application is for the preparation of cosmetic compositions with anti-wrinkle activity.
A method of cosmetic care for promoting the adhesion of the keratinocytes of the epidermal basal layer to the dermo-epidermal junction, comprising the steps of determination of the parts of the skin in need thereof and application to said parts of a cosmetic composition containing an active agent selected from the group consisting of magnesium salts, magnesium complexes, and mixtures thereof, in an efficient amount for promoting said adhesion.
The method according to claim wherein said composition comprises between 0.01 and 1% by weight of said active agent, based on the total weight of the composition.
