The primary ingredient in most exfoliating products is alpha hydroxy acids (AHAs). AHAs are naturally occurring acids derived from fruits and milk, and they are specifically known for their ability to effectively exfoliate the skin by promoting the shedding of dead skin cells. This process helps to improve skin texture, enhance radiance, and allow for better absorption of other skincare products.

AHAs such as glycolic acid and lactic acid are commonly found in many topical formulations because they are gentle on the skin while still providing significant exfoliation benefits. This makes them particularly popular for use in a variety of cosmetic and skincare products, from cleansers to serums.

While beta hydroxy acids, salicylic acid, and microdermabrasion crystals are also used for exfoliation, they serve different functions or are found in more specialized products. For instance, beta hydroxy acids are often more suited for oily or acne-prone skin due to their ability to penetrate pores, and salicylic acid specifically targets acne. Microdermabrasion crystals are more abrasive and typically used in professional treatments rather than in everyday products. Hence, AHAs remain the more prevalent choice in most exfoliating formulations.
