The SPF number in sunscreen indicates its level of protection against UVB rays, which cause sunburn. The higher the SPF number, the greater the protection. For example, SPF 30 blocks about 97 of UVB rays, while SPF 50 blocks about 98. This means that a higher SPF number offers more sun protection.

It was probably SPF 30 because that blocks 96.7% of UVB rays. SPF 50 blocks 98% so you aren't really getting that much more protection than the SPF 30. Neutrogena has a SPF 100 but it really isn't necessary because as I said, SPF 30 is already blocking a significant amount, and SPF 50 doesn't even make that much more of a difference. Just for your information, SPF 100 blocks 99% of UVB rays so it REALLY doesn't do much more than SPF 50.
