Azelaic acid is a naturally occurring dicarboxylic acid used topically to treat acne and rosacea, working through antibacterial, anti-inflammatory, and comedolytic actions. It also inhibits tyrosinase, helping reduce hyperpigmentation.
Salicylic acid is a lipid-soluble beta-hydroxy acid that exfoliates the skin surface and penetrates sebaceous pores to loosen and dissolve keratin and debris. It is widely used to treat acne, blackheads, and conditions involving thickened or scaly skin.
