Azelaic Acid

Calm redness, clear acne, fade dark spots

A 10–20% azelaic acid treatment (gel or cream) applied once or twice daily. It inhibits tyrosinase to fade post-inflammatory hyperpigmentation, kills acne-causing bacteria, reduces rosacea redness, and is safe through pregnancy — making it one of the most versatile skin actives available. Prescription 20% formulas show results in as little as 4 weeks.
