Nine popular sun protection products are exposing Australians to sunburn because they take too long to apply to get the right UV protection. The alarming discovery was made by Queensland University of Technology researchers who examined nine commercially available aerosol sunscreen products. Their research showed it could take between 4 to 14 seconds per limb and 29 to 98 seconds for a full body application to get the advertised UV protection. The actual time could be even higher as the tests were done in a laboratory in controlled conditions. Some also contained more propellant than sunscreen. The products investigated were: Ultra Sheer Body Mist Sunscreen and Beach Defence Sunscreen Spray from Neutrogena, Simply Protect Kids Spray, Sport Cool Zone Spray, Ultra Clear Spray, Dry Balance Clear Spray, all from Banana Boat, Tropic Silk Hydration Sunscreen Spray from Hawaiian Tropic, Sunscreen Sport Spray from Surf Life Saving, and Sunscreen Spray Everyday from Woolworths.
