Cosmetic and/or dermatological use of a composition containing at least one oxidation-sensitive hydrophilic active principle and at least one N-vinylimidazole polymer or copolymer

摘要

The invention relates to the use of a composition containing, preferably in a physiologically acceptable medium comprising an aqueous phase, at least one oxidation-sensitive hydrophilic active principle selected from the group consisting of ascorbic acid and its derivatives and at least one non-crosslinked N-vinylimidazole polymer or copolymer, the active principle and the polymer or copolymer both being present in the aqueous phase, for promoting the synthesis of epidermal ceramides and/or for improving the barrier function of the skin, among other uses.
