Abstract
The invention relates to a composition intended for the treatment of skin aging, containing, in a physiologically acceptable medium, at least one salicylic acid derivative corresponding to the formula: ##STR1## in which: R represents a saturated aliphatic chain or an unsaturated chain bearing one or more conjugated or unconjugated double bonds, it being possible for the chains to be substituted with one or more halogen atoms as well as with trifluoromethyl groups, with one or more hydroxyl groups in free form or a form esterified by an acid, or alternatively with a carboxyl group, free or esterified by a lower alcohol; and PA0 R' represents a hydroxyl group or an ester group of formula: ##STR2## where R.sub.1 is a saturated or unsaturated aliphatic group.
