How Safe is Azelaic Acid?
The safety of Azelaic Acid is one of the reasons for its popularity. Azelaic Acid is non-toxic and most people have a very high tolerance for its properties when applied topically. A high amount of the acid can result in mild skin irritation, but this is infrequent. In addition, Azelaic Acid is not prone to photosensitivity, and does not cause antibiotic resistant bacteria like many other skin creams.
