The invention relates to a method of lengthening eyelashes, comprising: applying to the eyelashes an effective amount of mascara comprising a composition comprising, in a physiologically acceptable medium, at least one first polymer of formula (I):in which n is an integer which represents the number of amide units such that the number of ester groups present in said at least one structuring polymer ranges from 10% to 50% of the total number of all said ester groups and all said amide groups comprised in said at least one structuring polymer; R<1>, which are identical or different are each chosen from alkyl groups having at least 4 carbon atoms and alkenyl groups having at least 4 carbon atoms; R<2>, which are identical or different, are each chosen from C4 to C42 hydrocarbon-based groups with the proviso that at least 50% of R<2 >are chosen from C30 to C42 hydrocarbon-based groups; R<3>, which are identical or different, are each chosen from C2 to C36 hydrocarbon-based groups; R<4>, which are identical or different, are each chosen from hydrogen and C1 to C10 alkyl groups, with the proviso that at least 50% of all R<4 >are chosen from hydrogen; and a dispersion of particles of at least one second polymer that is film-forming and insoluble, in said medium.
