What is the main purpose of exfoliation in skincare?

The main purpose of exfoliation in skincare is to remove dead skin cells and promote cell renewal. This process helps to reveal healthier, more youthful skin by sloughing off the layer of dead skin that can make the complexion appear dull and uneven. By facilitating the turnover of skin cells, exfoliation also improves the skin's texture and can enhance the effectiveness of subsequent skincare products. Additionally, regular exfoliation can help prevent clogged pores and breakouts, contributing to a clearer complexion.

While hydration plays a significant role in overall skin health, it is not the primary objective of exfoliation. Protection against sun damage involves different strategies, including the use of sunscreen and protective clothing. Brightening the skin tone can be a secondary benefit of exfoliation due to the removal of dead cells, but it is not the central purpose. In essence, the primary focus of exfoliation is the promotion of cell renewal and the clearing away of dead skin, leading to a fresher, more vibrant appearance.
