What is the primary function of exfoliation in skin care?

1. To hydrate the skin

2. To remove dead skin cells

3. To increase oil production

4. To enhance skin color

The correct answer is: To remove dead skin cells

The primary function of exfoliation in skin care is to remove dead skin cells. This process helps to reveal the healthier, fresher skin underneath, promoting a smoother and more radiant complexion. By eliminating the layer of dead skin, exfoliation aids in preventing clogged pores, which can lead to acne and other skin issues. Additionally, it enhances the skin's ability to absorb products better, allowing for more effective treatment from moisturizers and serums. Regular exfoliation can also stimulate cell turnover, contributing to the overall health and appearance of the skin. Hydration is essential for skin care but is not the main role of exfoliation. While the process may indirectly improve the skin's ability to retain moisture, it does not provide hydration itself. Increasing oil production is not a function of exfoliation; instead, it focuses on refining the skin's texture and appearance. Enhancing skin color can occur as a result of removing dead cells, but it is not the primary concern of exfoliation.
