Which of the following products is typically used for skin exfoliation?

The choice of facial scrub as the correct answer is rooted in its primary function within skincare routines. Facial scrubs contain granular or textured elements that help physically remove dead skin cells from the surface of the skin. This process of exfoliation is essential for promoting a smoother texture, enhancing skin radiance, and allowing for better absorption of subsequent skincare products.

Moisturizers are designed to hydrate the skin, but they do not focus on removing dead skin cells. Sunscreen serves a different purpose: it protects the skin from harmful UV rays, without engaging in exfoliation. Similarly, makeup removers are formulated to cleanse the skin by removing makeup and impurities but do not provide the benefits associated with exfoliation. Therefore, facial scrubs are specifically formulated for skin exfoliation, making them the most suitable choice among the options provided.
