All you need is 60 seconds for a superior sonic clean! This rechargeable device removes four times more dirt, oil, impurities, makeup and pollutants – including tiny pollution particles known as PM2.5 – than hand cleansing.* It cleans hard-to-reach places and is suitable for twice-daily cleansing on all skin types, including sensitive skin. Choose from three speeds. One-minute shutoff keeps skin care consistent.
