The present invention relates to retinal time-containing compositions which generally improve the quality of the skin, in particular human facial skin, which contain an oil / water type emulsion in the form of a liposomal system and which have a low irritant effect on the skin. The composition of the invention comprises (a) a retinoid compound (b) an oil-soluble antioxidant, and (c) an emulsifier or wetting agent (surfactant). Retinoic acid, retinol, retinaldehyde or retinoic acid ester, most preferably retinol, is used as the retinol compound. Suitable oil-releasable antioxidants in oil are generally and preferably bytylated hydroxyethane or bytylated hydroxyanis. The composition according to the invention may optionally be present, for example, with an active ingredient which protects against bethylene, a soap, a wetting agent and a sunscreen. The formulation also contains a chelating agent (stone complexing agent). In the composition according to the invention, the retinoid active ingredient is preferably present in small-plate (vesicylamellar) vesicles (bladders) and is thus protected against various effects. ŕ |
