Abstract: A mascara applicator system for simultaneously separating, curling and applying mascara, stored in the system, to eyelashes having a first applicator arm with a brush on one end and a second applicator arm with a circular cylinder comb on one end with some embodiments rotateably connected to a circular U-shaped member to provide articulating surfaces for a human hand with a spring functionally mounted between for bringing the brush and circular cylinder comb on the first and second applicator arms into parallel relationship for being closed on an eyelash and being pull upward from 0-180° and away from the eye to simultaneously apply mascara and curl eyelash. The applicator arm with the brush on it being hinged to move out to 90° for use as a touch up mascara brush and returned back to its position as a first applicator arm in mascara applicator system.
