Alpha hydroxy acids (AHAs) and beta hydroxy acids (BHAs) are widely recognized as effective exfoliants in the field of skincare. AHAs are water-soluble acids derived from fruits and milk, such as glycolic acid and lactic acid. They work by breaking down the bonds between dead skin cells on the surface, which facilitates their sloughing off and promotes cell turnover, resulting in a brighter and smoother complexion. On the other hand, BHAs, like salicylic acid, are oil-soluble and are particularly effective for oily and acne-prone skin. They penetrate into the pores to help dissolve excess oil and dead skin cells, preventing clogged pores and promoting a clearer appearance. The primary function of both of these acid types is to enhance exfoliation in various skin types, making them popular choices in many skincare products designed for improving skin texture, diminishing the appearance of fine lines, and treating acne. Their exfoliating properties facilitate the renewal of skin, contributing to more youthful and healthy-looking skin.
