The invention relates to a composition comprising: a) a polyhydroxyalkanoate copolymer comprising the following polymeric units A, B and C: —[—O—CH(R1)—CH—CO—]-unit A —[—O—CH(R2)—CH—CO—]-unit B —[—O—CH(R3)—CH—CO—]-unit C in which: R1 denotes a linear alkyl radical having from 5 to 9 carbon atoms; R2 denotes a linear alkyl radical having a carbon number corresponding to the number of carbon atoms of the R1 radical −2; R3 denotes a linear alkyl radical having a carbon number corresponding to the number of carbon atoms of the R1 radical −4; b) an oily medium comprising a non-silicone oil chosen from ester oils, carbonate oils and nonpolar hydrocarbon oils having from 8 to 14 carbon atoms.

Cosmetic composition comprising a polyhydroxyalkanoate in an oily medium

Cosmetic use of at least one salicylic acid derivative of following formula (I) in which L represents a linear or branched hydrocarbon radical comprising from 1 to 12 carbon atoms and having or not having one or more ethylenic unsaturations, and X represents a radical chosen from &#x2014;OH and &#x2014;COH, and also its cosmetically acceptable salts, its solvates, such as its hydrates, and its isomers, in a composition comprising a physiologically acceptable medium, as cosmetic agent intended to promote the desquamation of the skin and/or to stimulate epidermal renewal.
