3 Speed Modes + Smart Timer: The cleaning brush has three intensities from low to high for massage, exfoliation and deep cleansing. In addition, the brush will stop briefly every 20 seconds to remind you to change zones. The brush will automatically stop after 60 seconds to prevent over cleaning.100% waterproof + wireless charging + egg shape: 100% waterproof can be used in the bathroom or shower. The holder is very convenient and can be used to place or charge the brush (battery life is 30-45 days when fully charged). In addition, the ergonomic egg-shaped design can be held comfortably in the hand without taking up too much space.Perfect cleansing effect: it is gentler on the skin than a rotating brush. The vibrating brush gently cleanses the face and penetrates deep into the pores to remove dirt, dead skin, makeup residue and blackheads. It is 7 times more efficient than manual cleaning. From the first use, you will see smoother and clearer skin than usual.
