Exfoliants are skincare products designed to remove dead skin cells from the surface of the skin. They help to improve skin texture, promote cell turnover, and can enhance the effectiveness of other skincare products. Exfoliants come in two main types: physical and chemical. Physical exfoliants use small particles or tools to scrub away dead skin, while chemical exfoliants contain acids or enzymes that dissolve the bonds holding dead skin cells together. Regular exfoliation can lead to a brighter complexion and may help prevent clogged pores, which can reduce the risk of acne. However, it's important to use exfoliants appropriately, as over-exfoliating can irritate the skin. Popular ingredients in chemical exfoliants include alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs).
