What is the main purpose of an exfoliant in skincare?

The main purpose of an exfoliant in skincare is to remove dead skin cells. Exfoliation is a crucial process that helps to slough away the outer layer of dead skin that can accumulate on the skin's surface. This dead cell buildup can lead to a dull complexion, clogged pores, and uneven skin texture. By using an exfoliant, whether it is a physical scrub or a chemical exfoliant, you're promoting cell turnover and allowing healthier, fresher skin to emerge. This not only enhances the skin's appearance but also improves the effectiveness of other skincare products by allowing them to penetrate better.

While other functions like adding moisture, brightening the skin, or protecting against sun damage play important roles in skincare, they are not the primary purpose of exfoliation. Exfoliation mainly targets the removal of dead skin cells, making it a foundational practice for achieving smooth and radiant skin.
