A chemical exfoliant primarily removes dead skin cells from the surface of the skin through chemical reactions. These exfoliants often contain active ingredients such as alpha hydroxy acids (AHAs) or beta hydroxy acids (BHAs) that work by breaking down the bonds that hold dead skin cells together, making it easier for them to shed. This process promotes cell turnover, resulting in a smoother and more refined skin texture. Additionally, by removing these surface cells, chemical exfoliants can help improve the overall appearance of the skin, making it look more vibrant and youthful.

While brightening the skin tone can be a side benefit of using a chemical exfoliant, especially if it helps to alleviate dullness caused by dead skin build-up, it is not the primary function. Similarly, a chemical exfoliant does not remove facial hair or moisturize the skin—these actions are related to other types of products or treatments.
