What is the primary function of exfoliation in skincare?

To hydrate the skin

To remove dead skin cells

The primary function of exfoliation in skincare is to remove dead skin cells. This process is essential because it helps to prevent the buildup of these cells on the skin’s surface, which can lead to a dull appearance, clogged pores, and potentially result in breakouts. By effectively sloughing off the outer layer of dead skin, exfoliation promotes cell turnover and reveals fresh, new skin underneath, resulting in a brighter and smoother complexion.

Additionally, exfoliation can enhance the absorption of subsequent skincare products, making them more effective. It helps to improve overall skin texture and tone, allowing for a more radiant and healthy-looking skin surface. While hydration, skin color enhancement, and UV protection are vital aspects of a comprehensive skincare routine, they are not the primary purpose of exfoliation.
