A dry exfoliation brush is a skincare tool designed for manual exfoliation of the skin without the use of water or any liquid products. Typically featuring a handle for easy grip, the brush consists of firm, natural or synthetic bristles that are densely packed together. These bristles may be made from materials such as natural fibers, like boar hair, or synthetic materials like nylon.

The brush is specifically crafted for use on dry skin, and its primary purpose is to slough away dead skin cells, stimulate blood circulation, and promote cell turnover. Dry exfoliation helps improve the skin's texture, unclog pores, and enhance the absorption of skincare products applied afterward.
