Willow Bark Water
What it is
A watery distillate of white willow (Salix alba) bark, valued in skincare as a natural source of salicin, the plant precursor to salicylic acid, and used in toners and light essences for a mild clarifying, exfoliating effect.
How it works
Salicin carried in the water can be partially converted to salicylic acid on the skin, giving mild keratolytic action alongside general skin-conditioning and soothing benefits from the bark's other phenolic constituents.
