What is Birch Bark Extract Powder?
Birch Bark Extract Powder is derived from the outer bark of birch trees (commonly Betula alba or Betula pendula), a botanical source rich in triterpenes, particularly betulin and betulinic acid.
This extract is widely recognized in cosmetic, nutraceutical, and research fields for its skin conditioning, antioxidant, and structural support properties. Due to its high concentration of bioactive compounds, birch bark extract is increasingly used in premium skincare formulations and advanced botanical systems.
Our product is manufactured using controlled extraction and purification techniques to ensure high triterpene content, consistent quality, and formulation versatility.
