Azelaic Acid Cream 15%

Azelaic acid is a topical dicarboxylic acid used for acne, rosacea, and hyperpigmentation disorders such as melasma and post‑inflammatory hyperpigmentation. It exerts multi‑mechanistic effects: antibacterial against Cutibacterium acnes, anti‑inflammatory via TLR‑2 and ROS pathways, comedolytic/keratinization‑normalizing, and anti‑tyrosinase to reduce excess melanin. Randomized studies show 15% cream improves acne lesion counts and lightens hyperpigmentation over 8–24 weeks, including in darker skin types.
