Abstract: The present invention relates to a new cosmetic or pharmaceutical composition charactrized in that it comprises at least on vitamin component chosen from the group consisting of vitamin C and its derivatives, vitamin A (or retinol) and its derivatives, and mixtures of these components, in association with at least one fucose component chosen form the group consisting of fucose, polysacharides and oligosaccharides that contain fucose, sisting of fucose, polysaccharides and oligosaccharides that contain fucose, and mixtures of these components, as well as at least one acceptable excipient. This composition enables one to reduces significantly, by means of a real synergy effect, the toxic effect of the vitamin component and, therefore, to use in the composition contents of the vitamin component higher or equal to the contents of the products that already exist on the market without any risk for the user.
