Arisaema Amurense Extract (marketed as Melazero) is a plant-derived ingredient used in topical formulations for its proposed tyrosinase-inhibiting and antioxidant properties, aimed at reducing hyperpigmentation and evening skin tone. Clinical data on its standalone efficacy and safety in humans is limited.
