Lol, the SPF doesn't decrease the amount of rays that pass through the skin(when you get to normal amounts), it just means the length of time you can have it on before you have to reapply.

Eg. An spf of 15 blocks somethign like 93% of rays, spf 30=96% and an spf of 2=50% but I don't think anyone uses anything lower than 15 nowadays so it wouldn't make that much of a difference, especially between 30, 35,40,45, 50 etc...

For the length of time the spf means whatever times longer you can stay in the sun without getting burned than normally. Eg. if you burn in 10 minutes a SPF of 30 lets you stay out for 300min before being burned. Of course this is only good for things like walking, everyday use like going to work, etc... If you exercise, swim, whatever the sublock won't stay on for as long and you'll need to apply sooner.
