What It Does

Salix Alba Bark Extract is derived from the bark of the white willow tree and is naturally rich in salicin, a beta-hydroxy acid precursor that converts to salicylic acid in the skin. This botanical extract has been used for centuries for its anti-inflammatory and analgesic properties, and in modern cosmetics, formulators value it as a gentler, more natural alternative to synthetic salicylic acid, providing mild exfoliation, pore refinement, and soothing benefits with less irritation potential. The extract also contains polyphenols and flavonoids that contribute additional antioxidant and skin-conditioning effects.
