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 R' represents a hydroxyl group or an ester group of formula: ##STR2## where R.sub.1 is a saturated or unsaturated aliphatic group.
Claims11
A method for the treatment of the skin to lessen wrinkling, modify its color, reduce surface pigmented spots, eliminate squamae, or impart a softer feel to the skin comprising applying to the skin in an amount effective to treat said skin a composition comprising, in a physiologically acceptable medium, at least one salicylic acid derivative having the formula ##STR5## wherein R represents a linear, branched or cyclized saturated aliphatic chain having from 3 to 11 carbon atoms, and
- R' represents a hydroxyl group or an ester group having the formula ##STR6## (II), wherein R.sub.1 is a saturated or unsaturated aliphatic group having from 1 to 18 carbon atoms,
- said salicylic acid derivative being present in an amount ranging from 0.1 to 10 percent by weight relative to the total weight of said composition.
A method of treatment of actinic aging of the skin due to repeated exposure of the skin to sunlight comprising applying to the skin in an amount effective to treat the skin a composition comprising, in a physiologically acceptable medium, at least one salicylic acid derivative having the formula ##STR7## wherein R represents a linear, branched or cyclized saturated aliphatic chain having from 3 to 11 carbon atoms, and
- R' represents a hydroxyl group or an ester group having the formula:
- ##STR8## (II), wherein R.sub.1 is a saturated or unsaturated aliphatic group having from 1 to 18 carbon atoms,
- said salicylic acid derivative being present in an amount ranging from 0.1 to 10 percent by weight relative to the total weight of said composition.
