Abstract
An anhydrous cosmetic makeup composition contains in addition to a fatty phase formed from oils, fatty bodies and surfactants, and optionally waxes, a vesicular lipidic phase that contains at least one ionic or nonionic amphiphilic lipid and optionally additives. The anhydrous composition also preferably contains at least one cosmetically and/or dermopharmaceutically active material. In the presence of an aqueous phase these compositions release vesicles of the vesicular lipidic phase and potentialize the activity of the cosmetically and/or dermopharmaceutically active material of the composition.
