The intensity of UVA radiations can be controlled while the intensity of UVB radiations is subject to change. The intensity of UVB radiation varies so the SPF of a product will be based on its capacity to protect against UVB rays.

Although SPF is an excellent indicator of protection offered by a sunscreen against UVB radiation, it doesn't guarantee protection from UVA rays. A broad-spectrum sunscreen with an SPF range of 15-30 is the most effective. The SPF number isn't a measure of quality but rather a standard to determine the effectiveness of a sunscreen.

The SPF of a sunscreen product is measured under artificial conditions. A sunscreen with a higher SPF rating can provide more protection against UVA rays and may have additional benefits.

In addition, SPF ratings can be misleading because a sunscreen is able to wash off easily after being exposed to water. In the end, the effectiveness and substantiality of a product will only be established through in-vivo testing.
