skin school: AZELAIC ACID

Everything you need to know about this sensitive skin saver

- AMY ADAMS

Sure, you may be familiar with hyaluronic, glycolic, or salicylic acids and their many benefits, but they’re certainly not the only ingredients capable of boosting your glow.

The lesser-known but just as effective (albeit for different reasons) azelaic acid is fast becoming a buzz-worthy ingredient in its own right. We asked facialist Jocelyn Petroni for the lowdown on what it is and why you might need it.

What is azelaic acid?

This naturally occurring acid is actually a derivative of yeast and, according to Petroni, is often found in grains such as wheat, rye, and barley. “It has antimicrobial and anti-inflammatory properties, making it perfect for sensitive skin as well as a great ingredient for those suffering from acne, skin blemishes, acne scarring, redness, rosacea and more,” says Petroni.

How does it work? According to Petroni, azelaic acid works as a “gentle leave-on exfoliant” and is great for reducing inflammation, clearing pores, and stimulating cell turnover.
