Skin exfoliants are products used to remove dead skin cells from the surface of the skin. A common type of skin exfoliant is a SCRUB, which is a product that contains small particles that help to remove the dead skin cells. Scrubs can be made from natural ingredients such as sugar, salt, and oatmeal, or from synthetic materials such as polyethylene beads. Scrubs are often used in combination with other skin care products to help improve the overall appearance of the skin.
