Azelaic Acid

Azelaic acid is one of those hot ingredients with data showcasing its ability to help tackle major skin concerns such as hyperpigmentation, acne, and even rosacea. However, the challenge with this ingredient is that in order to achieve these benefits you’ll need a LOT of it in your skincare (read: major formula challenges for chemists). The other difficulty is that it’s also regulated so you typically would need a prescription to get those higher concentrations (15-20%) and won’t be able to purchase more than a 10% azelaic acid topical as a cosmetic.
