Abstract:
The subject matter of the invention is a method for making up eyelashes which consists in: a) coating the eyelashes with a deposit of at least one composition comprising, in a physiologically acceptable medium, at least one compound which enables the composition to attain, in the at least partially dry state, a modulus of rigidity Gp greater than or equal to 1 GPa, b) in the presence of a stimulus to which said compound is sensitive, placing a shaping tool in contact with the eyelashes thus coated in such a way as to modify the curvature of the eyelashes, wherein said placing in contact is maintained until the modulus of rigidity Gp of the composition is at least equal to 1 GPa, wherein the stimulus is selected in such a way that the modulus of rigidity of at least 1 GPa is obtained in a time t less than the time t0 that would be necessary to obtain said modulus by allowing the deposit to dry at ambient temperature.
