AHA (Alpha Hydroxy Acid) and BHA (Beta Hydroxy Acid) are well-known for their role in chemical exfoliation. They work by breaking down the bonds between dead skin cells, which helps to gently slough away these cells from the skin's surface. This process promotes cell turnover, resulting in smoother and brighter skin. Chemical exfoliation is particularly effective for improving skin texture, unclogging pores, and reducing the appearance of fine lines and wrinkles.

While AHA and BHA can contribute to benefits like moisturization or anti-aging, their primary function in skin care products lies in exfoliation. AHA is water-soluble and primarily derived from fruit, making it effective for surface exfoliation, while BHA is oil-soluble, allowing it to penetrate deeper into the pores and is more suited for treating acne-prone skin. Thus, their essential impact on skin care is indeed chemical exfoliation, which is foundational for maintaining healthy and radiant skin.
