What is the primary purpose of exfoliation?

The primary purpose of exfoliation is to remove dead skin cells and promote cell turnover. This process is essential in maintaining healthy skin, as it helps to eliminate the layer of dead skin that can accumulate on the surface. By doing so, exfoliation reveals fresh, new skin underneath, which can enhance the overall appearance and texture of the skin.

Additionally, promoting cell turnover is crucial for maintaining the skin's vitality, as it helps prevent clogged pores, reduces the risk of breakouts, and can improve the absorption of skincare products. Exfoliation can be achieved through various methods, including physical exfoliants (like scrubs) and chemical exfoliants (like alpha hydroxy acids or beta hydroxy acids), both of which effectively encourage skin rejuvenation.

The other choices do not accurately reflect the main purpose of exfoliation. While hydrating the skin is important for its health, it is not the primary focus of exfoliation. Similarly, stimulating hair growth or enhancing skin pigmentation are not related to the exfoliation process.
