SPF 100 is not necessarily overkill, but it may offer only marginally better protection than SPF 50. Both provide strong defense against UVB rays, which cause sunburn. SPF 50 blocks about 98% of UVB rays, while SPF 100 blocks about 99%. More important is regular reapplication and using enough sunscreen, especially after swimming or sweating.
