A must for outdoor lifeguards! One application provides and retains its SPF for 8 hours, no matter how much you sweat or how long you swim! Body Therapeutics Sunscreen is a light, dry water based lotion that completely penetrates within 2 minutes of applying; even sand won't stick. It is PABA-free, oil-free, fragrance-free, and blocks both UVA and UVB rays to provide maximum protection from the sun.
