Name: Round Lab Birch Juice Moisturizing Sunscreen

About This Product

Round Lab's Birch Juice Moisturizing Sunscreen doubles as a lightweight morning moisturizer and broad-spectrum UV protector. Infused with amino acid- and mineral-rich Betula Platyphylla Japonica Juice (Inje Birch Sap), Glyceryl Glucoside, Hyaluronic Acid, Niacinamide, and Allantoin, it hydrates parched skin without chalkiness or heavy residue. U.S. Regulatory & Formulation Note: Round Lab produces two distinct regional formulations—the Korean domestic SPF50+ PA++++ version (using Uvinul A Plus, Uvinul T 150, Tinosorb M, and Iscotrizinol) and the U.S. FDA OTC-compliant Birch Moisturizing Sunscreen UVLock SPF 50 Broad Spectrum (using Avobenzone, Homosalate, and Octisalate). Because the U.S. storefront substitutes the UVLock OTC reformulation, direct purchase for the original Korean formula is omitted here.

Where to Buy & U.S. Regulatory Status

This Korean domestic SPF formulation utilizes next-generation UV filters that are not currently monographed under U.S. FDA OTC sunscreen regulations. Because the U.S. storefront either restricts checkout for the Korean UV-filter version or substitutes a separate U.S. OTC-reformulated SKU, a direct U.S. purchase link for this exact Korean formulation is omitted.
