White birch (Betula pendula, also known as silver birch, warty birch, European white birch or Asian white birch) is a deciduous tree native to Europe and parts of Asia. Eurasians and First Nations have used it as a medicinal plant for centuries.
Science
The bark of white birch trees is rich in skin actives — betulin, lupeol, flavonoids and phenolic compounds — that promote skin health through several different mechanisms.
Studies show that birch bark extract increases skin hydration and strengthen the skin’s barrier function, reinforcing antioxidant defenses. The phenolic compounds in white birch reduce free radicals, preventing the oxidation involved in skin aging.
White birch is also rich in compounds that are known to prevent pigmentation disorders and suppress the formation of dark spots such as those caused by pollution and aging.
