Which chemical agent is often used in chemical peels for acne?

Salicylic acid is frequently used in chemical peels for acne due to its unique properties. It is a beta hydroxy acid (BHA), which means it has the ability to penetrate the oil glands and help exfoliate the skin from within. This property makes it particularly effective for treating acne, as it can unclog pores and reduce the formation of acne lesions.

In addition to its exfoliating capabilities, salicylic acid has anti-inflammatory properties that help to soothe redness and swelling associated with acne. Its ability to dissolve excess oil and dead skin cells is crucial for preventing future breakouts, making it a preferred choice in acne treatments.

Other acids, such as glycolic acid (an alpha hydroxy acid or AHA), lactic acid, and citric acid, serve different functions. While they can also provide benefits for the skin, such as surface exfoliation and improving skin texture, they do not penetrate the oil glands as effectively as salicylic acid. This limitation makes them less targeted for acne treatment compared to salicylic acid.
