What is the most common form of chemical exfoliation?

Alpha Hydroxy Acids (AHAs) are the most common form of chemical exfoliation due to their widespread use and effectiveness in skincare. AHAs, such as glycolic acid and lactic acid, are water-soluble acids derived from fruits and milk. They work by loosening the bonds between dead skin cells, facilitating their removal from the surface of the skin, and promoting cell turnover.

The popularity of AHAs in various skincare products, including cleansers, toners, and peels, makes them easily accessible for both professionals and consumers. This widespread availability contributes significantly to their common usage in various treatment protocols and at-home exfoliation routines.

AHAs also provide additional benefits beyond exfoliation; they help in improving skin texture, reducing the appearance of fine lines and wrinkles, and enhancing overall skin brightness and clarity. This multifaceted approach to skin improvement further establishes AHAs as a staple in chemical exfoliation practices.

While Beta Hydroxy Acids (BHAs) such as salicylic acid and other ingredients like retinoids also serve important roles in skincare, they are generally more targeted either at treating oily skin and acne or at deeper skin rejuvenation, respectively, rather than being the primary choice for general exfoliation.
