As an antioxidant, azelaic acid neutralizes free radicals and decreases inflammation. Azelaic acid also inhibits tyrosinase and produces a direct anti-proliferative effect on the melanogenesis pathway. It does not affect the normal melanocytes and does not lead to ochronosis on prolonged use as seen in 4% hydroquinone.
Azelaic acid has also been found to be an effective treatment to help reduce the appearance of acne, especially in adult women. Research has demonstrated that topical azelaic acid can play an important role in the acute management and maintenance of adult acne due to its anti-inflammatory mechanism of action.
Azelaic acid is a chemical compound found naturally in some grains as well as in a fungus called Malassezia furfur that grows on the skin.
Topical use of azelaic acid is well tolerated, with adverse effects limited to generally mild and transient local cutaneous irritation.
There is minimal data on contraindications for the topical application of azelaic acid. Although rare, patients with an allergy to azelaic acid, its components or its byproducts should avoid use of products containing azelaic acid.
