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.
Kojic acid is a fungal-derived organic acid that inhibits tyrosinase, reducing melanin production and helping to fade hyperpigmentation, melasma, and dark spots. It is commonly used in topical depigmenting formulations.
