This twin-head rotating cleansing brush delivers intensive cleansing. It pinpoints and thoroughly removes stubborn dead skin and sebum around the nose, leaving your skin feeling smooth and silky. The ultra-fine bristles measure approximately 70 microns. The two twin heads rotate inward to remove impurities deep within hard-to-reach pores. Regular use will thoroughly cleanse even the finest impurities. The rotating heads have a low-speed mode (approximately 500 rotations per minute) and a high-speed mode (approximately 600 rotations per minute), allowing you to choose the mode that best suits your skin type. By moving the brush from bottom to top along the contours of your face, massaging it, you can simultaneously remove impurities and firm your skin. The device is splash-proof (IPX5), so it can be used in the bathroom, even with wet hands. It runs on two AAA alkaline batteries (sold separately).
