The purpose of an exfoliating scrub in a facial is primarily to remove dead skin cells and promote cell renewal. This process helps to slough off the outermost layer of skin, which can become dull and rough due to the accumulation of dead skin cells. By exfoliating, you not only reveal fresher, more vibrant skin underneath but also encourage the skin’s natural regeneration processes. This can lead to a smoother texture, enhanced brightness, and improved overall skin tone.

While moisturizing the skin is important in a facial, it is not the primary function of an exfoliating scrub. The scrub itself does not provide sun protection nor is it directly related to enhancing makeup application, although smoother skin can make makeup go on more evenly. Therefore, the focus of an exfoliating scrub lies in its ability to effectively renew the skin's surface by removing impurities and promoting a healthier complexion.
