Broussonetia papyrifera (paper mulberry) bark extract is a plant-derived ingredient used in topical formulations primarily for its tyrosinase-inhibiting and antioxidant properties, helping to reduce hyperpigmentation and even skin tone. It is commonly included in products targeting dark spots and melasma.
