Abstract
Disclosed are cosmetic compositions and methods for making up keratinous tissue using the compositions, as well as methods of making the compositions. The compositions contain a photoluminescent polymer (PLP) which is an oligomeric polyester synthesized from a multifunctional monomer and a diol, and which has grafted thereon an amino acid or an amino acid derivative. The compositions achieve a colorizing and/or UV-protectant effect when applied to keratinous tissue.
