The intensity of UVA radiations is fixed, while the intensity of UVB Rays fluctuates. The intensity of UVB radiation varies , therefore the SPF of a product will be based on its ability to shield against UVB rays.

Although SPF is a good indicator of the protection offered by sunscreens against UVB radiation, it doesn't guarantee protection from UVA radiation.

The SPF of sunscreen products is measured under artificial conditions. A sunscreen with a higher SPF rating can provide better protection against UVA radiation and could offer additional advantages. A product with a lower SPF isn't "broad spectrum" since it doesn't provide protection against UVB radiation. The SPF is a measurement of the protection provided by the product. Before buying sunscreen, it is important to understand the SPF and how it works.

The FDA has created a labeling requirement to sunscreens that are labeled with the word SPF. A higher SPF does not necessarily mean better UVA protection than an SPF that is lower. The same applies to broad-spectrum products that contain SPF. Furthermore, SPF figures can be misleading as a sunscreen is able to wash off easily after being exposed to water. In-vivo testing is the sole way to determine the effectiveness and substantiality.
