The Round Lab Birch Juice Moisturizing Sunscreen is one of Korea’s most popular sunscreens for a reason. It is designed to combine the highest level of UV protection with premium skincare. The power of birch sap, rich in amino acids and antioxidants, revitalizes dry, irritated skin, while hyaluronic acid ensures long-lasting moisture retention. The formula contains niacinamide, which helps fade dark spots, and vitamin E, which acts as a shield against environmental damage. It’s also an excellent choice for sensitive skin, as it’s enriched with soothing allantoin and doesn’t leave a greasy feeling.
