Applied topically in cream, gel, or foam formulations (typically 15-20% at prescription strengths, around 10% in over-the-counter cosmetics), it exerts anti-inflammatory, antioxidant, and antimicrobial actions and inhibits the enzyme tyrosinase. It works in part by scavenging free radicals, reducing the reactive oxygen species released by neutrophils, and normalizing the aberrant cathelicidin/kallikrein-5 innate-immune signaling implicated in rosacea, and it is FDA-approved for the topical treatment of rosacea. ## Its role in longevity Multiple randomized controlled trials, Cochrane reviews, and meta-analyses find that topical azelaic acid significantly reduces inflammatory lesions and erythema in papulopustular rosacea - a systematic review of five trials (873 patients) found four of five superior to vehicle - and a 2019 GRADE-assessed review classed it among the topicals with high-certainty evidence. Head-to-head data suggest it is at least as effective as topical metronidazole, although some analyses rank topical ivermectin as more effective, and it has not been shown to reduce telangiectasia; evidence for acne and melasma is also supportive. One honest caveat: most rigorous trials used prescription 15-20% strengths, so benefit at over-the-counter ~10% cosmetic doses is plausible but less directly proven. Benefits typically take one to two months to appear, and mild, transient stinging or irritation is the most common side effect. This evidence describes the azelaic acid compound and its mechanisms, not this specific commercial gel product. ## Evidence grade: Strong evidence - **What the grade means:** Curated grade based on the human and mechanistic evidence for this compound. - **Dose used in studies:** 15-20% topical gel/cream (prescription strengths used in most trials) - **What this grade does not say:** Strong dermatology evidence for rosacea, acne and melasma at prescription 15-20% strengths, built on decades of RCTs and GRADE-assessed reviews. Benefit at over-the-counter ~10% cosmetic doses is plausible but less directly proven. Mild, transient stinging is the most common side effect; a skin-health product, not a systemic longevity intervention. ## In the news - **Azelaic Acid Gel** — Cleveland Clinic 2026 [Read it](https://my.clevelandclinic.org/health/drugs/18644-azelaic-acid-gel) > It works by decreasing inflammation and killing or preventing the growth of bacteria on your skin. - **Is Azelaic Acid Good for Your Skin?** — WebMD 2026 [Read it](https://www.webmd.com/skin-problems-and-treatments/what-to-know-about-azelaic-acid-skin) > But multiple studies have shown that about 70%-80% of people see their rosacea symptoms improve. - **Topical Treatment for Rosacea** — NYU Langone Health 2026 [Read it](https://nyulangone.org/conditions/rosacea/treatments/topical-treatment-for-rosacea) > It has been demonstrated to improve the appearance of redness and to reduce blemishes and whiteheads caused by rosacea. ## The research Peer-reviewed studies on the active compound.
