Photoblock Gel SPF50 is a sun protection product that offers high-level UV defense in a gel formulation. This 75g sunscreen is designed to protect against harmful UVA and UVB rays while providing a lightweight, non-greasy feel on the skin. As this is a sun protection product, it should be applied generously to clean, dry skin at least 15-30 minutes before sun exposure. For optimal protection, reapply every 2 hours or after swimming, sweating, or towel drying. The gel format makes it suitable for daily use and can be worn under makeup.
