Azelaic Acid is a naturally occurring dicarboxylic acid found in grains like wheat and barley. It is known for its powerful ability to reduce acne, treat rosacea, and brighten post-acne marks without irritating the skin. Azelaic Acid helps normalize keratinization (cell turnover), reduce bacterial overgrowth (C. acnes), and calm inflammation. It's ideal for use in leave-on serums, creams, and gel formulations — especially for acne-prone, sensitive, and dull skin types.
