Which process is commonly used to promote skin exfoliation?

Chemical peels are a well-known method for promoting skin exfoliation. This process involves applying a chemical solution to the skin that causes the outer layer to peel away, revealing fresher, smoother skin underneath. Chemical peels can vary in strength and depth, targeting different skin concerns such as acne, pigmentation, and aging. The active ingredients commonly used in chemical peels, such as alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs), work to break down the bonds between dead skin cells, facilitating their removal and promoting cellular turnover.

In contrast, moisturization is generally aimed at enhancing the skin's hydration and barrier function, rather than directly promoting exfoliation. Hydration therapy focuses on increasing the moisture levels within the skin but does not involve the removal of dead skin cells. Tanning treatments, such as applying self-tanners or undergoing tanning beds, are intended for altering skin color and as such do not contribute to skin exfoliation.
