What the science says
Azelaic acid has strong evidence for helping acne clear, often beating a placebo and working about as well as tretinoin 1. For rosacea, the research has strong evidence too, with studies finding it reduced spots and redness, though it did not seem to help visible blood vessels 2. For dark patches, azelaic acid has some evidence of fading melasma, while results for other pigment concerns were mixed 3. Stinging and burning were the most common side effects in those pigment studies 3.
