Did you know???.......The SPF number in your suntan lotions is the level of protection the sunscreen provides against UVB rays ONLY, which are the main cause of sunburn. A higher SPF number means more UVB protection. People often do not apply enough sunscreen, so the actual protection they get is less. Sunscreens labeled with SPFs as high as 100+ are available. Higher numbers do mean more protection, SPF 15 sunscreens filter out about 93% of UVB rays, while SPF 30 sunscreens filter out about 97%, SPF 50 sunscreens about 98%, and SPF 100 about 99%. The higher you go, the smaller the difference becomes. No sunscreen protects you completely. Sunscreens with broad spectrum protection (against BOTH UVA and UVB rays) AND with sun protection factor (SPF) values of 30 or higher are recommended.
