What the science says
Azelaic acid has strong evidence for clearing acne, often beating a placebo and working about as well as tretinoin 1. For rosacea, it has strong evidence for reducing spots and redness, though it did not appear to help visible blood vessels 2. Its use for dark spots has some evidence behind it, with the clearest gains seen in melasma 3.
