Which chemical is commonly used for chemical peels to exfoliate the skin?

Glycolic acid is widely recognized as a common ingredient in chemical peels used for skin exfoliation due to its effectiveness and ability to penetrate the skin. As an alpha hydroxy acid (AHA), it is derived from sugar cane and is known for its smaller molecular size, allowing it to effectively penetrate the outer layer of the skin. This makes glycolic acid particularly suitable for promoting cell turnover, improving skin texture, and reducing the appearance of fine lines, acne scars, and pigmentation issues.

Additionally, glycolic acid works by breaking down the bonds that hold dead skin cells together on the surface, thereby helping to remove these cells and reveal fresher, healthier skin underneath. This property makes it a favored choice among estheticians for chemical peels aimed at enhancing skin aesthetics, as it provides visible results with continued use.

The other options, while also used in various skincare treatments, serve different purposes or are utilized in different context relative to chemical peels. Salicylic acid, for instance, is primarily used for treating acne due to its ability to penetrate oil-filled pores. Lactic acid, another AHA, is milder than glycolic acid and is often used for sensitive skin or hydration. Acetic acid is typically associated with vinegar
