What is the role of exfoliation in acne treatment?

Exfoliation plays a critical role in acne treatment primarily by removing dead skin cells from the surface of the skin. When dead skin cells accumulate, they can mix with sebum (the skin's natural oil) and block hair follicles, which can lead to the development of acne. By regularly exfoliating, this buildup is reduced, helping to prevent clogged pores and allowing for healthier skin cell turnover.

In addition to preventing clogged pores, exfoliation can also enhance the effectiveness of topical treatments by improving their penetration into the skin, promoting a clearer and smoother complexion over time. This is crucial in managing and treating acne, as it addresses one of the core issues that contributes to breakouts.

The other options present incorrect roles: Adding moisture does not directly relate to how exfoliation functions in acne treatment, increasing oil production is counterproductive in managing acne, and promoting skin thickness does not align with the benefits provided by exfoliation. Thus, the focus on dead skin cell removal is central to its effectiveness in acne management.
