Maple Water (or Maple Sap) is highly prized in Korean Beauty because of its tiny molecule size, allowing it to quickly penetrate your skin, delivering its antioxidant-rich goodness throughout. We chose Maple Water as a base for our essence/toner, to serve as a prepping stage for your face to absorb your other serum layers, facial oils and moisturizers even better. Our Maple Essence Toner is over 80% Maple Water.
