Product consisting of polymer particles, wherein the polymer particles are chosen from particles of: (a) polymers derived from keratin, where appropriate modified; (b) silk fibroin; (c) polymers derived from chitin, where appropriate deacetylated; (d) synthetic polymers chosen from: (i) crosslinked polymethyl methacrylate; (ii) crosslinked poly- beta -alanine; (iii) hollow microspheres of vinylidene chloride/acrylonitrile copolymer; (iv) porous microspheres of polyamide 12, polyamide 6 or copolyamide 6/12; (v) silicone powders consisting of gums, resins or organopolysiloxane elastomers, these particles having a particle size of less than 100 microns and containing a natural or synthetic melanin pigment at the surface and/or in the polymer network, this pigment being either formed beforehand and absorbed by the particles or formed in situ by oxidation of an indole dye. |
