Which ingredient is commonly used in chemical exfoliation?

Chemical exfoliation is a process that involves the removal of dead skin cells from the surface of the skin using specific chemical agents. Alpha Hydroxy Acids (AHAs) are widely recognized for their effectiveness in this regard. They are water-soluble and primarily derived from fruits, making them suitable for exfoliating the surface layers of the skin.

AHAs, such as glycolic acid and lactic acid, work by breaking down the bonds that hold dead skin cells together, allowing for easier shedding and promoting cell turnover. This process not only improves skin texture but also enhances hydration and can help fade hyperpigmentation, making it a popular choice in esthetic treatments.

While beta hydroxy acids (BHAs) such as salicylic acid are also effective exfoliants, particularly for oily or acne-prone skin, AHAs are more commonly associated with general chemical exfoliation for overall skin rejuvenation. Glycolic acid, a specific type of AHA, is renowned for its potency and ability to penetrate the skin effectively, but it falls under the broader category of AHAs. Thus, identifying AHAs as a commonly used ingredient in chemical exfoliation is accurate, positioning it as the correct answer.
