This device uses gentle suction and a fine mist to deeply clean pores without harsh chemicals. The mist helps the suction cup form a tight seal against your skin to more effectively remove oil and dirt from pores, reducing blemishes and the appearance of large pores for healthier, revitalized skin. The reversible suction cup has a slim, 3/16" wide side that allows you to easily clean hard-to-reach areas around the eyes, nose, and chin and a 7/16" wide side for cleaning the cheeks and forehead. The pore cleanser's waterproof housing allows for use in a shower, where the warm water helps open pores and facilitate a more thorough cleaning. The cordless device operates for 20 minutes after a 12-hour charge. Charging stand plugs into AC. 7 2/3" H x 3 1/2" W x 2" D. (11 oz.)
