10% azelaic acid for redness, acne, and PIH; pilling is real.

What the community says

Backed by 44 studies

A silicone-heavy 10% azelaic acid suspension for acne, redness, and post-breakout marks. Redditors call it a starter azelaic option, and studies back azelaic acid for acne. The catch is pilling, thickness, and stinging on reactive skin.
