Azelaic Acid Suspension 10% — Reddit Reviews
by The Ordinary
Updated September 23, 2026
10% azelaic acid for redness, acne, and PIH; pilling is real.
What the community says
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.
