1. A method for treating human skin or hair for reducing or combating cellulite or signs of cellulite and/or for reducing local fat accumulation and/or for combating time- and/or light-induced ageing processes of the skin or hair which comprises applying to human skin and/or hair at least one compound of the formula (I), which compound is active for achieving one or more of the above effects, where R1 stands for a straight-chain or branched C1- to C20-alkyl group, R2 stands for
H orstraight-chain or branched C1- to C20-alkyl group, R4 stands for
H,straight-chain or branched C1- to C20-alkyl group orstraight-chain or branched C2- to C20-alkenyl group having one or more double bonds, R3 stands for a radical selected from
H,straight-chain or branched C1- to C20-alkyl group,straight-chain or branched C2- to C20-alkenyl group having one or more double bonds, where the alkenyl group may also be substituted by one or more saturated or unsaturated C3- to C12-cycloalkyl groups,straight-chain or branched C2- to C20-alkynyl group having one or more triple bonds,saturated or unsaturated C3- to C12-cycloalkyl group, where the rings may in each case also be bridged by —(CH2)n— groups where n=1 to 3,an acyl radical of the formula —C(═O)—R6, R6 stands for
straight-chain or branched C1- to C20-alkyl group,a radical of the formula (II) in which X stands for straight-chain or branched C1- to C6-alkylene or straight-chain or branched C2- to C6-alkenylene and the radicals R5 are selected, independently of one another, from H, OH, straight-chain or branched C1- to C6-alkyl or straight-chain or branched O—(C1- to C6-alkyl). |
