Azelaic acid is a naturally occurring dicarboxylic acid widely used in cosmetics, pharmaceuticals, and specialty chemical applications. It is mainly used in skincare formulations for acne treatment, skin brightening, and anti-inflammatory products due to its antibacterial and keratinization-regulating properties. It is also applied as a raw material for polymer synthesis, plasticizers, lubricants, and chemical intermediates.
