The intensity of UVB radiation is different, so the SPF of a product will depend on its ability to shield against them.
Although SPF is a good indicator of the protection offered by sunscreens against UVB radiation, it does not guarantee protection from UVA rays. A broad-spectrum sunscreen that has an SPF between 15-30 is the best. The SPF numbers do not mean quality, but it is an indicator of the effectiveness of sunscreens.
The SPF of sunscreens is measured under artificial conditions. A sunscreen that has an SPF rating that is higher will provide greater protection from UVA Rays and may also offer additional benefits. A product with a lower SPF can’t be called “broad spectrum” because it isn’t protected against UVB rays. SPF is an indicator of the amount of protection the product can offer. Before buying sunscreen it is crucial to know the SPF and how it works.
The FDA has established a labeling requirement for sunscreens that are labeled with the word SPF. A higher SPF does not necessarily mean greater UVA protection than an SPF that is lower. The same applies to broad-spectrum products with SPF. SPF numbers are often misleading because sunscreens can easily be washed away when exposed to water. Testing in-vivo is the only method to assess the effectiveness and substantivity.
