摘要:
Cosmetic use for a topical application of a composition comprising 1% or less by weight with respect to the total weight of the composition of one or more compounds of formula (I): ** Formula ** in which R1 to R4 and R1 'a R4', identical or different, each represents: - either a hydrogen atom, - or a halogen atom, - or an ORx, SRx or NRxRy group in which (i) Rx and Ry, independently from each other, are selected from the hydrogen atom, the alkyl groups (C1-C6), cycloalkyl (C3-C6), aryl (C6-C18), aryl (C6-C18) alkyl (C1-C4), (C1-C12) alkyl (C6-C18) aryl, (C3-C6) cycloalkyl (C6-C12) aryl, (C5-C12) heteroaryl comprising 1 to 3 heteroatoms, NR'R "and NHCOR'R", R 'and R' being, independently of each other, selected from the hydrogen atom and the (C1-C6) alkyl, cycloalkyl (C3-C6), aryl (C6-C12), and the heterocycles of (C5- C12), aromatic or not, comprising 1 to 3 heteroatoms or ( ii) Rx and Ry together form a hydrocarbon chain, linear or branched having 2 to 6 carbon atoms, which eventually comprises one or more double bonds and / or eventually interrupted by an oxygen, sulfur or nitrogen atom, - an ORx group in which Rx corresponds to a saturated or unsaturated fatty acid (C4-C20), a bear or an amino acid; or its cosmetically acceptable salts or complexes, to treat or prevent a degradation of the skin extracellular matrix resulting from a drop in the testosterone rate.Utilización cosmética para una aplicación tópica de una composición que comprende el 1% o menos en peso con respecto al peso total de la composición de uno o varios compuestos de fórmula (I):**Fórmula** en la que R1 a R4 y R1' a R4', idénticos o diferentes, representan cada uno: - o bien un átomo de hidrógeno, - o bien un átomo de halógeno, - o bien un grupo ORx, SRx o NRxRy en el que (i) Rx y Ry, independientemente el uno del otro, se seleccionan de entre el átomo de hidrógeno, los grupos alquilo (C1-C6), cicloalquilo (C3-C6), arilo (C6-C18), arilo (C6-C18) alquilo (C1-C4), alquilo (C1-C12) arilo (C6-C18)
