What is the primary purpose of exfoliation in skincare?

1. To hydrate the skin

2. To enhance product absorption

3. To remove dead skin cells

4. To prevent acne

The correct answer is: To remove dead skin cells

The primary purpose of exfoliation in skincare is to remove dead skin cells. This process helps to unclog pores, improve the skin's texture, and promote cell turnover, which can result in a more radiant and youthful appearance. By regularly exfoliating, the skin can better absorb serums and moisturizers, leading to enhanced effectiveness of these products. While exfoliation can aid in preventing acne by clearing away the buildup of dead skin that could clog pores, the fundamental action of exfoliating is the removal of these dead cells. It's also important to note that while it can play a role in hydration, that's not its main goal; hydration primarily comes from moisturizers and serums designed to hold water in the skin. Thus, the focus of exfoliation is clearly centered on the removal of dead skin cells, making this the correct answer.
