This is a replacement head for the Clinique Sonic System Cleansing Brush. A revolution in skin cleansing, the Sonic System Brush provides gentle cleansing that unclogs pores by lifting makeup and dirt to give your skin a more thorough, deeper clean. The Purifying Cleansing head has been designed to provide intensive cleansing without being rough on the cheeks, utilising a flat bed of bristles along with an angled tip to reach hard-to-get-to areas.
