USE OF A COMBINATION OF 2-METHYLENE-1,4,5,6-TETRAHYDRO-4-PYRIMIDINCARBOXYLIC ACID OR THE DERIVATE THEREOF AND A BLUE-GREEN ALGAE EXTRACT FOR INCREASING THE SKIN BARRIER FUNCTION

摘要

The invention relates to a combination of at least one compound of 2-methylene-1,4,5,6-tetrahydro-4-pyrimidine carboxylic acid or the derivates thereof and at least one blue-green algae extract and if necessary at least one fucose-containing polysaccharide (in particular in the embodiment of one of the cosmetic products of claims 1 to 6) stimulates the epidermal syntheses of filaggrin and/or transglutaminase and/or involucrin.
