FIELD: cosmetic industry.
SUBSTANCE: group of inventions relates to the cosmetic industry and is a microcomplex for use in photoepilation, which contains: nanocomplex that includes a nanoparticle from a material selected from the group consisting of metals, semiconductors, and mixtures thereof, supporting localized surface plasmon resonance that is coated through bond formation, coordination or covalent, poly cationic polymer or a heterobifunctional compound that contains a thiol group at one end of the molecule and a positively charged functional group at the other end, and adsorbed on the surface of a particle carrier with a diameter lying in the range from 100 nm to 2,000 nm, with the microcomplex having a positive Z potential exceeding 10 mV. Present inventions also relate to methods for producing this microcomplex and to its use in a photo-epilation method, as well as a composition containing a microcomplex, and an improved photoepilation method based on these microcomplexes.
EFFECT: group of inventions allows to increase the number of nanocomplexes reaching the target region, and to solve the problems associated with nanoscale nanocomplexes, while maintaining the photothermal properties of individual nanoparticles.
