Chemical exfoliants are skincare products that help remove dead skin cells using specific acids or enzymes. Unlike physical exfoliants, which use scrubs or brushes, chemical exfoliants work by dissolving the bonds that hold dead skin cells together, promoting a smoother and brighter complexion. Common types include alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs). These exfoliants can improve skin texture, reduce the appearance of fine lines, and help with issues like acne and hyperpigmentation. Regular use can lead to healthier skin, but it's essential to follow instructions and use sunscreen, as they can increase skin sensitivity to the sun.
