Round Lab's Birch Juice Moisturizing UV Lock is a lightweight, hydrating sunscreen designed to protect and replenish your skin in one easy step. With broad-spectrum SPF45, it shields your skin from both UVA and UVB rays — preventing sunburn, dark spots, and premature aging.
Powered by birch sap from Korea’s Inje region, this formula delivers deep hydration and soothing benefits, making it especially ideal for sensitive, combination, or oily skin types. Its gel-like texture absorbs quickly without leaving a white cast or greasy finish, making it a seamless fit under makeup or on bare skin.
