What is Glycolic Acid classified as?

Glycolic Acid is classified as an Alpha Hydroxy Acid (AHA) because it is derived from natural sources, specifically sugar cane. AHAs are well-known for their ability to exfoliate the skin by loosening the bonds between dead skin cells on the surface. This process promotes skin cell turnover, which can lead to smoother, brighter, and more even-toned skin. Glycolic Acid's small molecular size allows it to penetrate the skin effectively, making it a favored ingredient in many skincare formulations aimed at improving the skin's texture and elasticity.

In contrast, Beta Hydroxy Acids (BHAs), such as salicylic acid, are oil-soluble and are more effective for treating acne-prone skin due to their ability to penetrate oily pores. Cosmetic Acid and Carbonic Acid do not specifically relate to the classification of Glycolic Acid in the context of skincare or its functions, making them less relevant in this scenario.
