Abstract: A mascara brush has a wire core securing bristles extending radially therefrom. The bristles are trimmed to define applicator bristles and bristles extending in a longitudinal profile comb deployed along the core, the profile comb being longer than the applicator bristles. The core is curved in a plane passing through the profile comb whereby bristles extending from the convex side of the curved core diverge and bristles extending from the concave side of the curved core converge. The profile comb has a flat comb surface extending across its width, and the comb surface longitudinally curves to generally conform to eyelashes. For applying quick drying building or curling mascara, the profile comb extends from the concave side of the curved core. For applying heavier defining mascaras, the profile comb extends from the convex side of the core. The brush has bristles along one inch of its length, the bristles being secured in approximately sixteen turns of the brush at a density of 45 to 65 bristles per turn.
