What is one key ingredient commonly found in exfoliants?

Alpha hydroxy acids (AHAs) are indeed a key ingredient commonly found in exfoliants. These water-soluble acids are derived from fruits and are particularly effective in promoting the shedding of dead skin cells from the surface of the skin. AHAs help to improve the skin's texture, enhance luminosity, and reduce the appearance of fine lines and uneven pigmentation.

AHAs work by loosening the bonds that hold dead skin cells together, making it easier for the skin to naturally shed them. This gentle exfoliation process not only reveals fresher, younger skin underneath but also aids in the overall process of cell turnover, contributing to a healthier skin appearance over time.

While other ingredients listed, such as beta hydroxy acids (BHAs), salicylic acid, and retinol, also play significant roles in skincare and exfoliation, AHAs are particularly noted for their use in chemical exfoliants aimed at those with dry or sun-damaged skin.
