Salix Nigra (Willow) Bark Extract is a botanical source of salicin, a natural precursor to salicylic acid, valued for mild exfoliating, soothing, and antimicrobial properties. It is commonly included in formulations for acne-prone, oily, or sensitive skin as a gentler alternative to synthetic beta-hydroxy acids.
