Describe the process of exfoliation.

The process of exfoliation specifically involves the removal of dead skin cells from the surface of the skin. This is important because it helps to reveal healthier, more radiant skin underneath and can also improve the skin's texture and tone. Regular exfoliation can prevent clogged pores that may lead to acne and can enhance the effectiveness of other skincare products by allowing them to penetrate the skin more effectively.

Exfoliation can be achieved through various methods, including physical exfoliation (using scrubs or brushes), chemical exfoliation (using acids or enzymes), or mechanical methods (such as microdermabrasion or chemical peels). By removing the top layer of dead cells, exfoliation stimulates cell renewal and encourages fresh skin growth, contributing to a more vibrant appearance.

In contrast, other choices focus on different skincare processes that do not pertain to the removal of dead skin cells. For example, hydrating the skin is important for maintaining moisture balance, while sun protection is vital for preventing damage from UV rays. Massaging products into the skin helps with absorption but does not address the exfoliation process specifically.
