The Round Lab Birch Moisture Tone-Up Sunscreen is enriched with birch sap from Inje, providing a refreshing and revitalizing sensation. The 3-step hydration process opens the skin's moisture pathways, hydrates with birch sap, and locks in moisture with Vita Hyaluronic Acid, resulting in a dewy, naturally radiant, rosy complexion. This sunscreen offers triple-functional sun care, including UV protection, brightening, and wrinkle improvement. Ingredients we love Hyaluronic Acid: An intensely hydrating ingredient that visibly plumps the skin and reduces the appearance of wrinkles. Niacinamide: Stimulates natural ceramide production and fades hyperpigmentation, leading to firm, even-toned skin. Ascorbic Acid: A vital antioxidant that boosts collagen production, reduces pigmentation and dark spots, and enhances UV protection.
