Abstract: Esters of O-substituted hydroxy carboxylic acids are provided having Formula 1, or 2, or both Formulas 1 and 2: wherein R and R1 are independently selected from the group consisting of substituted and unsubstituted, branched- and straight-chain, saturated, unsaturated, and polyunsaturated C1-C22 alkyl, substituted and unsubstituted C3-C8 cycloalkyl, substituted and unsubstituted C6-C20 carbocyclic aryl, and substituted and unsubstituted C4-C20 heterocyclic; wherein the heteroatoms are selected from sulfur, nitrogen, and oxygen; and wherein n is 1-6. Process of producing esters of O-substituted hydroxy carboxylic acids are also provided.

Abstract: Cosmetic and therapeutic, in particular dermatological bioprecursors have the formula [A]n-PP-[B]m wherein PP is a polyphenol radical in which each hydroxyl function is protected by a group A or a group B, A is a saturated or unsaturated, substituted or unsubstituted alkyl radical having 1 to 20 carbon atoms which is bonded to the polyphenol, n is an integer not less than 1, and B is a precursor of a biologically active molecule, which is also bonded to the polyphenol, and m is an integer also not less than 1.

Abstract: A cosmetic or dermatological composition contains, in a physiologically acceptable medium, at least one compound from Formula (I). A method of using the composition, for reducing or preventing pigmenting, and/or whitening and/or lightening of the skin is described, as well as novel compounds from Formula (I?) that are included in Formula (I).
