Claims22
A cosmetic composition, comprising:
- (A) at least one acylproline represented by formula (I) or a salt thereof:
- wherein R1—CO— is an acyl group derived from a saturated or unsaturated fatty acid having 2 to 23 carbon atoms;
- and
- (B) at least one component selected from the group consisting of:
- (a) compound represented by formula (II) or a salt thereof:
- wherein R2 is an alkyl group having 5 to 11 carbon atoms, an alkenyl group having 5 to 11 carbon atoms, an alkynyl group having 5 to 11 carbon atoms, or an alkoxy group having 5 to 11 carbon atoms;
- and
- (b) a compound represented by formula (III) or a salt thereof:
- wherein R3 and R4 are each independently hydrogen, a hydroxy group, or —OCH3.
