Cosmetic and dermatological compositions, comprise a compound of low solubility and a lipophilic amino acid derivative, especially an ester of formula (AA), in a physiologically-acceptable medium. n = 0, 1, or 2; R'1 = 5 - 21C alkyl or alkenyl; R'2 = H or 1-3C alkyl; R'3 = H, or 1-4C alkyl; and R'4 = 1-10C alkyl, 2-10C alkenyl, or a sterol residue. An Independent claim is also included for a process of solubilizing a weakly soluble product by mixing it with a lipophilic amino acid derivative.
