What Is Betula Pendula Sap?
Betula Pendula Sap is the clear watery fluid tapped from the trunks of the silver birch tree (Betula pendula) in early spring when the thaw pushes nutrients up from the roots. Rich in natural sugars, amino acids, minerals like potassium and calcium plus small amounts of antioxidants and B vitamins, the sap has long been prized in Nordic and Baltic folk skin care rituals. Modern cosmetic chemists began looking at it in the late 20th century after studies showed its ability to hydrate and soften skin. Harvesting is done by drilling a small hole into the bark, collecting the flowing sap, then filtering and gently pasteurizing it to keep the delicate compounds intact. You can now spot Betula Pendula Sap in hydrating serums, lightweight moisturizers, soothing toners, sheet masks, anti aging creams and scalp care treatments where a boost of moisture and skin friendly nutrients is desired.
