Mulethi (licorice root, Glycyrrhiza glabra) is a botanical extract whose active compounds (glabridin, liquiritin) inhibit tyrosinase to reduce hyperpigmentation and provide soothing, antioxidant, and anti-inflammatory benefits. It is commonly used in topical formulations targeting dark spots, melasma, and skin irritation.
