What is the purpose of exfoliation in skincare?

Exfoliation serves the essential purpose of removing dead skin cells from the surface of the skin. This process is crucial for maintaining healthy skin, as the buildup of dead cells can lead to a dull complexion and can clog pores, which may result in breakouts. By effectively exfoliating the skin, fresh, new cells are able to rise to the surface, promoting a brighter, smoother, and more youthful appearance. Additionally, exfoliation can enhance the effectiveness of other skincare products, allowing them to penetrate more deeply and work more efficiently.

Hydration is vital for skincare, but exfoliation itself does not directly hydrate the skin; rather, it prepares the skin to better absorb hydrating products. Adding fragrance may enhance the sensory experience of a product but is not related to the exfoliation process. Similarly, creating a protective barrier is important in skincare but is not the primary function of exfoliation, which focuses specifically on cell turnover and renewal.
