Around the world, SolRX MINERAL SPF 50 Zinc Sunscreen with WATERBLOCK® is the trusted choice of athletes and lifeguards for protection against harmful UVA and UVB rays. Originally designed for triathletes, swimmers and surfers, our MINERAL SPF 50 Zinc Sunscreen offers broad-spectrum protection and it will not burn your eyes if you sweat. Differing from normal sports sunscreens, SolRX SPF 50 Zinc Oxide Sunscreen blocks the sun's harmful rays, instead of reflecting them. Regular sport sunscreens absorb into the skin in order to start working. Zinc Sunscreen physically blocks the sun by sitting directly on your skin, which is why most labels say to apply the mineral zinc oxide sunscreen about 20 minutes before entering the sun. Our SPF 50 sunscreen with Zinc Oxide is non-nano, oil-free and was engineered especially for athletes to go on clear with a matte finish so athletes can focus on play and exercise.
