Different SPF levels indicate the level of protection a sunscreen offers against UVB rays. The number correlates to the amount of time you can stay in the sun without getting a sunburn. An SPF 30 blocks 97% of UVB rays, while an SPF 50 blocks 98%, providing higher protection but not proportionally higher.

Would adding spf 30 sunscreen to spf 50 sunscreen make it spf 80 sunscreen?

No. SPF 30 lets in 1/30 of burning UV rays, while SPF 50 lets in 1/50. Adding the two together is pointless and would not result in high levels of skin protection.

Do all sunscreens offer the same protection?

No, not all sunscreens offer the same level of protection. Different sunscreens have varying SPF (Sun Protection Factor) levels and protection against different types of UV rays (UVA and UVB). It's important to choose a sunscreen with an SPF of 30 or higher and broad-spectrum protection for optimal sun protection.


What is the highest SPF facial sunblock can be purchased in?

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.
