Sun Bum's Zinc-Based Mineral Sunscreen Spray is an easy to apply, continuous spray mineral sunscreen that’s Fragrance Free and provides Broad Spectrum SPF 50 protection to help protect skin from UVA/UVB rays. Did you know? None of their sprays include chemical propellants; they opt for natural compression over aerosol! The air dispenses the product stored in a B.O.V (Bag on Valve) inside the container, steering clear of traditional aerosol methods.
