In today's environment, skin needs a deeper clean. That's why Clinique's dermatologist developed brush head was designed with two types of bristles for targeted cleansing. The angled tip tilts deep into the T Zone and gently but throughly cleanses larger areas like cheeks. It reaches into problem areas where make up, dirt and oil hang out and draws out impurities for to help get smooth, glowing skin and purified pores. Anti microbial technology helps keep bristles clean and fresh. Designed to be used with Clinique's Sonic System Purifying Cleansing Brush.
