Dicarboxylic Acid

Azelaic Acid

Azelaic acid is a naturally occurring dicarboxylic acid found in wheat, rye, and barley. It works through multiple mechanisms: inhibiting the enzyme tyrosinase (reducing melanin overproduction), exerting antibacterial action against Cutibacterium acnes, normalising keratin production in pores, and reducing inflammation. Unlike AHAs or BHAs, it is not classified as a chemical exfoliant but achieves similar pore-clearing and brightening results through a distinct biochemical pathway.
