You exfoliate your face with a scrub cream for face, a skincare product. It helps to slough dead skin cells off the surface of your skin which in turn decreases the chances of clogged pores and acne.  The practice of exfoliating the skin dates back to the times of the Pharaohs, when an abrasive was used to scrub and exfoliate. A lot of people notice dry patches on their skin.  These are called flakes. They are harmful and they make the skin look very dull. Use a facial scrub to exfoliate your face and remove flaky skin, smoothing it out.
