text: It is an object of the present invention to provide novel liposome or vesicle compositions consisting essentially of lecithin and between about 10 and 90%, preferably 16 and 90%, and especially between about 20 and 80%, by weight of a fatty acid-esterified collagen hydrolysate (FAECH) selected from fatty acid esterified lipoamino acids and lipopeptides, wherein the fatty acid contains from 8 to 24 carbon atoms, and a method for the preparation thereof, as well as the important aspect of vesicle dimensional control and particle size reduction by employing increased ratios of the specified fatty acid-esterified collagen hydrolysate, and further a method for the use thereof in cosmetic and/or pharmaceutical preparations or compositions, and the compositions themselves containing effective amounts of cosmetically or pharmaceutically-effective active ingredients, the vesicles or liposomes according to the present invention being characterized by unprecedented stability, non-aggregating properties, and impermeability, and wherein the particle size of the vesicle or liposome is reduced in proportion to an increase in the weight ratio of the specified fatty acid-esterified collagen hydrolysate to the lecithin present in the vesicle wall and in the mixture of ingredients employed in the production of the same.
