摘要

A cosmetic applicator brush having a twisted wire core and an array of thermoplastic bristles with free tips extending radially outwardly from the core, wherein at least some of the bristles have shapes and/or surface textures modified at one or more localities between their free tips and the core by selective irradiation of the aforesaid locality or localities with laser energy. A method of making the brush includes the steps of assembling the core and bristles to form a brush, trimming the bristles to achieve a desired brush profile, and selectively irradiating at least some of the bristles with a laser beam at localities between the bristle tips and the core.
