Abstract
The present invention relates to a composition for topical application on skin for photoepilation comprising nanocomplexes which comprise a nanoparticle supporting an LSP resonance which is coated with at least a chemical compound, wherein said chemical compound is selected from the group consisting of polyionic polymers, heterobifunctional compound of the surface assembled monolayer type, antibodies and their mixtures. The present invention also relates to a photoepilation method which comprises the steps of (i) applying to the skin surface the composition for topical application of the present invention, and (ii) applying a radiation to said surface of the skin.
