Cosmetic treatment of skin comprises applying compound, preferably gamma-aminopropyl triethoxysilane adapted to in situ condensation and compound, preferably dihydroxyacetone comprising reactive function to form a covalent bond, on skin

摘要

Method of cosmetic treatment of skin comprises applying a compound or group of compounds A adapted to in situ condensation and has at least one reactive function FA, which is free after condensation, and a compound C of cosmetic interest comprising a reactive function Fc susceptible to form a covalent bond by reaction with function FA, on skin, where the material resulting from the condensation of A is soluble in water and the reaction of the compound C of the material resulting from the condensation of A leads to a decrease in the solubility of the material in water. An independent claim is included for a cosmetic kit comprising at least a first composition comprising at least one compound or group of compound A and a second composition comprising at least one compound C, in a medium.
