Everyone swears by this ingredient for acne—here’s why

Dozens of acne-fighting products line the shelves at the drugstore. When a pimple crops up and you find yourself unequipped to deal with it, you may dash to the skincare aisle only to feel analysis paralysis. What products and active ingredients will work on your breakout, and how do you use them with your current routine?

There’s more than one solution forgetting rid of acne, but one tried-and-true method is to use an ingredient called salicylic acid. To explain why, we consultedDr. Suzanne Friedler, a board-certified dermatologist with Advanced Dermatology PC in New York City.

What is salicylic acid?

Salicylic acid is classified as abeta hydroxy acid(BHA) that, when applied topically, can break down oil and dead skin cells. It’s often used for treating acne-prone or oily skin types because it has the ability to soak down into the sebaceous glands and dissolve acne-causing oil. Friedler explains: “Oil is food for bacteria, so salicylic acid, by reducing some of the oil on the skin, also helps to prevent a breakout because less oil is less food for the bacteria.” It’s also a keratolytic, meaning it exfoliates the surface of the skin, causing dead skin cells to slough off to reveal new, healthier skin.

Salicylic acid can also address discoloration, such ashyperpigmentationormelasma, and brighten the skin’s appearance because of itsexfoliating abilitiesthat keep the skin cells turning over, says Friedler.

What skin types can benefit from salicylic acid?

Salicylic acid is best for oily or acne-prone skin—and, as mentioned, those two traits often overlap, as oil can lead to acne. You may try salicylic acid if you have normal or dry skin and experience bouts of acne, but a gentler exfoliant, likeglycolic acid(an alpha hydroxy acid, or AHA), may suit your skin better, particularly if you know yourskin is sensitive.

When adding any new ingredient into yourskincare routine，最好每周逐渐逐步整合它，以了解皮肤的反应。

Using salicylic acid in a wash-off treatment, like a cleanser, is a great way to add it into your routine to see how well you tolerate it. “Once it's done its job as a keratolytic, it's just done, so sitting [on the skin] is not really going to help you that much,” says Friedler.

The Cerave SA Cleanser claims to be gentle enough for daily use on all skin types and it containsceramidesthat protect the skin barrier, in addition to salicylic acid.
