This ultrasonic cleansing brush features a silicone outer layer with antibacterial silver ions and an inner layer made of SEBS rubber. The motor is suspended on the inner layer and works with even vibration, which enables efficient cleansing while protecting sensitive skin. As the diameter of the bristle tips on the curved surface gradually changes from 0.6 mm to 1.2 mm, different areas of the face can be treated properly with the device.
