10% azelaic acid for redness, acne, and texture; strong but can irritate.

What the community says

Backed by 64 studies

A 10% azelaic acid serum with cica and panthenol that Redditors keep grabbing for redness, breakouts, and rough texture. Studies back the acne side; the catch is that some rosacea and barrier-damaged users find it too strong or irritating.
