Which ingredient is commonly found in chemical exfoliants?

Alpha hydroxy acids (AHAs) are indeed commonly found in chemical exfoliants due to their effective properties in promoting skin cell turnover and improving skin texture. AHAs are water-soluble organic acids, such as glycolic and lactic acid, derived primarily from fruit and milk. They work by loosening the bonds between dead skin cells, allowing for easier shedding of these cells and revealing fresher, smoother skin underneath.

This exfoliation process not only helps in improving the appearance of fine lines and sun damage but also enhances skin hydration as AHAs can attract moisture to the skin. Their multifunctional benefits make AHAs a popular choice in various skincare formulations specifically designed for exfoliation.

While beta hydroxy acids (BHAs) are also used for similar purposes, they are oil-soluble and penetrate deeper into the pores, making them more suitable for oily or acne-prone skin. The other ingredients listed, mineral oil and petrolatum, are emollients that provide moisture and barrier functions rather than exfoliation. Thus, their inclusion in the context of chemical exfoliants is not relevant.
