The invention relates to compound of generic formula (I) in which: R1 and R2 represent: OH, a hydrogen atom, a C1-C6 alkyl radical a C1-C6 alkoxy radical, a halogen, or OCOR3; R3 represents: a C1-C24 alkyl radical a C12-C24 alkenyl radical comprising at least one unsaturation; R4 represents: COR5, a glucide substituted or not by one or more acetyl radical(s); R5 represents: a C10-C24 alkyl radical or a C12-C24 alkenyl radical comprising at least one unsaturation; R6 and R7 represent: - simultaneously a hydrogen atom or a methyl radical, or - when R6 represents a hydrogen atom, R7 represents a C1-C6 alkyl radical or a phenyl substituted or not by one or more C1-C3 alkoxy radical(s) or one or more halogen(s) or - R6 and R7 are bonded together and form a C3-C6 cycloalkyl, and pharmaceutically or cosmetically acceptable salts.
