Do I need sunscreen with more than 30 SPF?

Tuesday, August 05, 2014

Short answer: No
Sunscreens with an SPF (sun protection factor) of 30 block about 97% of ultraviolet rays,
While sunscreens with an SPF of higher than 30 block 97%-98%.
It's more important that you choose "broad-spectrum" sunscreen, meaning it protects against both UVB and UVA rays.
Sunbathers also need to apply a generous amount of sunscreen in order to get the full benefit of the SPF.
