ROUND LAB Birch Juice Moisturizing Serum is a lightweight, fast-absorbing formula that delivers intense hydration without any greasy residue, leaving your complexion dewy and supple. The serum works through a three-step moisturizing system. Glyceryl Glucoside opens your skin's moisture pathways by promoting Aquaporin production. Birch Sap then boosts moisture retention deep within the skin. Finally, Vita Hyaluronic Acid creates a protective moisture barrier to lock in hydration throughout the day. With just a few drops, experience silky-smooth skin that feels refreshed and nourished. Perfect for anyone seeking long-lasting moisture and a radiant, healthy glow.
