Exfoliation refers to the removal of dead skin cells, leaving behind the smoother skin underneath. One way to exfoliate is to use a facial scrub, which can buff away oil, dirt and dead skin cells—and subsequently mat down facial hair and block your razor's path. But did you know that shaving can also exfoliate dry skin? After exfoliating with a wash and shave, make sure to rinse with cool water to close pores and soothe the skin. Then, pat your face dry and apply a light, oil-free after-shave balm or lotion to help refresh and seal in your skin's natural moisture barrier.
