This hydrating serum is formulated with 70 % Japanese White Birch sap (Betula Platyphylla Japonica Juice) and multiple types of hyaluronic acid. It deeply moisturizes, helps prevent moisture loss, and supports the skin’s barrier. The formula also includes a soothing ABC Complex (Allantoin, Betaine, Cucumber Extract) and panthenol to calm sensitivity and balance skin’s oil-moisture levels. With a mildly acidic pH and lightweight texture, it layers well under other skincare and makeup.
