Short answer: No
Sunscreen 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.
