What is the role of exfoliation in skincare?

Exfoliation plays a crucial role in skincare primarily by removing dead skin cells that accumulate on the surface and promoting skin renewal. This process helps to reveal fresher, healthier skin underneath, which can enhance overall skin texture and appearance.

When dead skin cells are cleared away, it can improve the effectiveness of other skincare products by allowing them to penetrate more deeply and work more efficiently. Additionally, regular exfoliation can stimulate cell turnover, leading to a brighter complexion and potentially reducing the appearance of fine lines, uneven texture, and hyperpigmentation.

While hydration is important for maintaining skin's health, exfoliation itself does not directly increase skin hydration; rather, it can create better conditions for hydration to be effective. Exfoliation does not provide sun protection, which is a separate aspect of skincare, typically achieved through the application of sunscreen. Lightening skin tone is also not the primary purpose of exfoliation, though it can contribute to a brighter appearance by revealing newer skin. Therefore, the act of exfoliation itself is fundamentally about removing dead skin and promoting renewal for better skin health.
