Which skin concern is primarily addressed through exfoliation?

Exfoliation primarily targets the issue of dead skin buildup. This process involves the removal of the outermost layer of dead skin cells from the epidermis, which can occur through various methods such as mechanical scrubs or chemical exfoliants. By eliminating this buildup, exfoliation helps to reveal fresher, healthier skin underneath, which can enhance overall skin texture and appearance.

While other options may relate to skin health, they are not the primary concerns addressed by exfoliation. Moisture retention usually involves hydration techniques rather than cell turnover. Dark spots, often resulting from sun damage or hormonal changes, typically require treatments like serums or lasers rather than merely exfoliation. Skin irritation can be alleviated by gentle, soothing treatments and proper care routines, not by aggressive exfoliation, which might exacerbate irritation instead. Thus, the focus on dead skin buildup highlights the main benefit of exfoliation in achieving clearer and more radiant skin.
