Which ingredient is commonly used in chemical peels for exfoliation?

Glycolic acid is a well-known ingredient used in chemical peels for exfoliation due to its properties as an alpha hydroxy acid (AHA). It works effectively by breaking down the bonds between dead skin cells on the surface of the skin, which facilitates their removal and encourages cell turnover. This exfoliation reveals fresher, more youthful skin underneath, improving texture and tone.

Additionally, glycolic acid has a small molecular size, allowing it to penetrate the skin more deeply compared to other exfoliants. This deeper penetration enhances its effectiveness in treating skin concerns such as dullness, uneven skin tone, and signs of aging. Its popularity in aesthetic treatments comes from its ability to provide visible results with minimal downtime, making it a preferred choice for both professionals and clients seeking skin rejuvenation.

Other ingredients, such as salicylic acid, are also used in peels but generally target oily and acne-prone skin conditions due to their ability to penetrate and clear out pores, rather than focusing purely on overall exfoliation. Hyaluronic acid, on the other hand, is primarily used for hydration rather than exfoliation, while retinoic acid is more focused on promoting cell turnover and treating specific skin issues like acne, but it is less commonly used
