What Acid Removes Skin?

Several acids are used to remove layers of skin for various cosmetic and medical purposes. The most common acids include salicylic acid, glycolic acid, and lactic acid. These are all alpha-hydroxy acids (AHAs) or beta-hydroxy acids (BHAs), which have exfoliating properties.

Salicylic Acid: A Multi-Purpose Skin Exfoliant

Salicylic acid is a beta-hydroxy acid (BHA) frequently used in topical treatments for acne, psoriasis, dandruff, and calluses. It works by softening and loosening dry, scaly, or thickened skin, allowing it to be removed more easily. ^{1, 5, 7, 9, 10} High concentrations are also found in products marketed for removing skin lesions like moles and skin tags. ² Importantly, while it removes skin, it’s crucial to remember that improper use of high-concentration salicylic acid products can cause injuries and scarring. ²

Glycolic Acid: A Chemical Exfoliant for Smoother Skin

Glycolic acid, an alpha-hydroxy acid (AHA), is another common chemical exfoliant. It removes the outermost layer of skin cells and oil by dissolving them, leading to a smoother, brighter complexion. ^{3, 8} It's often used in chemical peels to remove skin cells from the epidermis. ⁴

Lactic Acid: A Gentle Exfoliant

Lactic acid, also an AHA, is known for its gentler exfoliating properties. It removes dead skin cells, contributing to a smoother and brighter appearance. ⁸ Like glycolic acid, it’s used in some chemical peels. ⁶

Chemical Peels and Skin Removal

Chemical peels utilize these acids, often in combinations, to remove layers of skin. The depth of skin removal varies depending on the type of peel and the concentration of the acid used. ^{4, 6} Medium chemical peels, for example, remove cells from the epidermis. ⁴

Important Note: Always consult a dermatologist before using any acid-based skin treatment, especially if you have sensitive skin or pre-existing skin conditions.
