The more powerful the SPF, better. SPF 15 protects against 93% of UVB Rays, whereas SPF 30 blocks 99.6 percent. SPF 60 is able to block 96 percent UVB radiations. However, if you are susceptible to skin cancer, you'll require a higher degree of protection. The American Academy of Dermatology recommends that you use a broad-spectrum sunscreen with an SPF of 30 or higher and avoid the sun from 10 a.m. to noon.

Because they block both types of radiations, broad-spectrum sunscreens provide broad-spectrum protection. When selecting a sunscreen, ensure that the SPF is at least 15 or greater.
There are certain limitations in the measurement of the SPF. The test performed on humans uses controlled conditions to determine the degree of protection.

The SPF of a sunscreen product is measured under artificial conditions. A sunscreen with a higher SPF rating will provide greater protection from UVA Rays and may also offer additional advantages.

Before purchasing sunscreen products it is crucial to know the SPF and how it works.
SPF is a labeling obligation set by the FDA for sunscreen products. However, a higher SPF is not always better for UVA protection than a lower one, and the same applies to SPF of a broad-spectrum sunscreen.

In the end, the efficacy and substantivity of a sunscreen can only be confirmed through in-vivo tests.
