What is the role of exfoliation in a skincare regimen?

Exfoliation plays a crucial role in a skincare regimen by removing dead skin cells and promoting cell turnover. This process helps to reveal fresher, healthier skin underneath and contributes to a smoother texture, clarity, and an overall more radiant appearance. When dead skin cells accumulate on the surface, they can lead to dullness, clogged pores, and uneven skin tone. By regularly exfoliating, you encourage the skin to shed these old cells, making way for new ones to emerge, which can enhance the skin's ability to absorb other products, such as moisturizers and serums, more effectively.

While nourishing the skin with vitamins and creating a protective barrier are also important aspects of a skincare routine, these functions are not the primary purpose of exfoliation. Increasing oiliness would contradict the benefits of exfoliating, as the process generally helps to balance the skin's oil production.
