Is it true that you can stay out in the sun almost twice as long if you are wearing an SPF 50 than you can if you only use a SPF 30 sunscreen?


It sounds like SPF 50 is way stronger than SPF 30 but the truth is that SPF 30 sunscreens filter about 96.7% of UV radiation while SPF 50 sunscreens filter 98% of UV radiation.
