The present invention relates to a makeup and/or care method of a nail and/or false nail, comprising a) applying a photocrosslinkable cosmetic composition (C1) onto a nail or false nail b) exposing the coated nail or false nail obtained in step a) to UV or visible light radiation and then photocrosslinking to obtain a crosslinked layer (C&prime1) c) applying a photocrosslinkable cosmetic composition (C2) onto the nail or false nail coated with the crosslinked layer (C&prime1) obtained in step b) and d) exposing the coated nail or false nail to UV or visible light radiation and then photocrosslinking to obtain a crosslinked layer (C&prime2) the composition (C1) comprising in a physiologically acceptable medium at least one photocrosslinkable compound comprising at least two (meth)acrylate functions and at least one carboxylic acid function, at least one volatile solvent (S) in a proportion greater than or equal to 30% in relation to the total weight of the composition (C1), and at least one photoinitiator the composition (C2) comprising, in a physiologically acceptable medium, 65 wt. % or more in relation to the total dry extract of (C2) of at least one photocrosslinkable urethane di(meth)acrylate compound, and at least one volatile solvent (S&prime).
