Scrubs come in many formulations for face and body. They can be in gel, cream or liquid form. It is important not to rub too aggressively as this can scratch and damage the skin. Used in the correct w...ay for your skin type, scrubs and peels slough away the dead skin cells leaving skin fresh and clean. Scrubs should be used as a gentle exfoliator to take off the superficial top layer of skin. Scrubs should not be used on pustular spots as this can break the skin and spread infection.
