What is Salix Alba (White Willow) Bark Extract?

Salix Alba (White Willow) Bark Extract derives from the bark of the Salix alba tree, a deciduous species native to Europe and western Asia. It features bioactive compounds like salicin—a phenolic glucoside—along with tannins, flavonoids, and polyphenols. In cosmetics, it appears as an aqueous, glycolic, or powdered extract in toners, cleansers, serums, shampoos, and conditioners. It works primarily through astringency, where tannins constrict surface tissues for a refined feel; mild keratolytic action from salicin hydrolysis supports gentle exfoliation; anti-inflammatory flavonoids calm sensitivity; and antioxidants neutralize free radicals. This multifunctional profile suits it for leave-on and rinse-off formulations targeting skin tone, scalp health, and overall conditioning without harshness.
