Botanical. Native to Europe, North America. Derived from the leaves of Salix alba (white willow), a tree native to Europe and western Asia in the Salicaceae family. Extracted from leaves using solvent extraction methods to obtain the active compounds.
Willow leaves contain salicin and have been traditionally used in herbal preparations for skin conditions and inflammation. The leaf extract is used in modern cosmetics for its potential exfoliating and clarifying properties.
