Products Description
White Willow Bark Extract is a natural plant‑derived cosmetic ingredient extracted from Salix alba bark, standardized for salicin-the natural precursor of salicylic acid (BHA). Combined with flavonoids, polyphenols, and phenolic acids, it delivers gentle exfoliation, anti‑inflammatory, oil‑regulating, antioxidant, and barrier‑repair benefits. Widely used in skincare for acne‑prone, sensitive, dull, and aging skin with high stability and formulation compatibility.
