by TIRTIR
Updated September 1, 2026
12% azelaic acid clarifies acne and redness; can dry or disrupt skin barrier.
What the community says
A liquidy 12% azelaic acid serum with zinc and panthenol targets acne, redness, and texture. Daily or twice-weekly use improves pigmentation and spots, though sensitive or dry skin can experience barrier damage and dryness. Start slow, hydrate well to avoid irritation.
