Ok, so my main question is: Is there really any difference between SPF 30 and SPF 50+? I’ve read mixed answers on this. I know that the higher the SPF, the longer you can stay out in the sun. But let’s say you where out in the sun for ONE HOUR, with SPF 30. Would it provide the same protection as being in the sun for ONE HOUR, with SPF 50? If I re-apply the SPF 30 often, will it be exactly the same as SPF 50?

Other question, what do you think is more important: Higher levels of Zinc Oxide, or higher SPF rating? (I’m talking about sun-block here, NOT sun-screen. There’s a difference). I want the highest protection possible, so I want a sun-block that is an actual BLOCK, where it just provides a barrier on your skin nearly completly blocking out the sun. That’s what I want. NOT a sun-screen. But rather a complete Sun BLOCK. The two products I was looking at: one is SPF 30 and contains 17% Zinc Oxide in it. The other product I was looking at is SPF 55, but contains less Zinc Oxide at only 13.5%. Which do you think is more effective? The higher SPF, or higher Zinc Oxide? I know higher zinc means it provides more protection and reflects the sun even more – but will SPF 30 be enough? If I re-apply 17% zinc sunblock with SPF 30 often would it be a better choice than the 13.5% zinc with 55 SPF? I always re-apply sun-block on average every 2 hours while out in the sun, sometimes even sooner. So my guess is that the SPF 30 shouldn’t even be worn off in that amount of time – meaning SPF 55 wouldn’t even be providing any extra protection since I’m re-applying the SPF 30 before it even wears off. Am I right?

The SPF (Sun Protection Factor) does not exactly indicate how long you can stay out in the sun. You are smart to use a high SPF – and to reapply frequently.
