A good broad spectrum sunscreen will protect against most of the UVA and UVB spectrum from at least 370nm to 280nm. UVC is not a concern because it does not penetrate past the ozone layer and thus does not reach our skin.

What can block UVC?

Levels of ozone at various altitudes (DU/km) and blocking of different bands of ultraviolet radiation: In essence, all UVC is blocked by diatomic oxygen (100–200 nm) or by ozone (triatomic oxygen) (200–280 nm) in the atmosphere. The ozone layer then blocks most UVB.

What is the difference between UVA and UVB and UVC?

UVA rays have the longest wavelengths, followed by UVB, and UVC rays which have the shortest wavelengths. While UVA and UVB rays are transmitted through the atmosphere, all UVC and some UVB rays are absorbed by the Earth’s ozone layer.
