Rotating Makeup Brush – Apply foundation or concealer by dabbing it on your chin, cheeks, nose and forehead. A small amount of makeup goes a long way! Rotary button to turn on and off. For best results don't apply in a circular motion, glide the brush head side to side or up and down, allowing the brush do the work for you! Turn on the brush so that the brush starts to rotate. Start blending by holding the ergonomic handle and gliding it slowly across your face side to side and up and down....
