Let's be real: the million-plus strong r/SkincareAddiction subreddit is an absolute gold mine of skin care tips and advice. One Reddit-approved ingredient that's been grabbing our attention lately? Azelaic acid.

It's not just a passing trend, either — it's got the dermatologists' seal of approval. "Azelaic acid is a fruit acid derived from grains such as wheat, rye, and barley," says board-certified dermatologist, Dr. Peterson Pierre, MD. "It's been around for years, and is fantastic for acne and rosacea because of its anti-inflammatory and antimicrobial properties. It also helps improve the appearance of pores, tone and texture, and eliminates whiteheads, blackheads, and pigmentation."

One small warning: It might take a little getting used to (though this isn't the case for everyone). "When you first start using it, you may experience some stinging, burning, redness, peeling, or dryness," he explains. "Those symptoms typically resolve within a week or two. It causes a gentle exfoliation, which helps improve the tone and texture of your skin."
