A body scrub is an exfoliant that can be used all over your skin (excluding your face). Just like an exfoliant for your face, scrubs typically use something like dead sea salt. This is to help your skin shed that outer layer of dead skin cells. This is important because dead skin cells can pile up on your skin. This leads to clogged pores, rough or dry skin, and dull skin. In addition, scrubs can also target any problems or areas that regular soaps do not. For example, brighter skin, stretch marks, and much more!
