Exfoliation is a crucial step in facial treatments primarily aimed at removing dead skin cells from the surface of the skin. As skin cells naturally renew themselves, older cells can accumulate, leading to a dull and uneven complexion. By effectively exfoliating the skin, you can promote a smoother texture and allow newer, healthier cells to emerge. This process not only enhances the skin's appearance but also helps in preventing clogged pores and improving the overall efficacy of subsequent skincare products.

While other options address important aspects of skin health and aesthetics, they do not directly relate to the primary function of exfoliation. Adding moisture is important for skin hydration, enhancing glow is a byproduct of various skincare practices including moisturizing and serums, and stimulating hair growth is unrelated to the exfoliation process. The focus on the removal of dead skin cells underscores the foundational role that exfoliation plays in maintaining skin health and achieving a radiant complexion.
