The Rechargeable Facial Cleansing Brush is a new concept for its new type of brush. The brush consists of two metal tubes, an outer tube that fits into the inner tube, with the bristles being contained in the inner tube. The outer-tube of the rechargeable brush is usually made of durable plastic material, while the inner tube has a long thin metal wire which carries the bristles to the inside of your cheek. The wire allows you to use the brush anywhere without fear of damaging or scratching the brush itself.
The ability of the rechargeable-brush to maintain the right form, density, and hardness of the bristles is because they run on a smart timer controlled by either a built-in microprocessor or rechargeable battery.
