SPF is a sunscreen score that protects against UVB rays
Although SPF is a popular measurement of the protection a sunscreen provides, it's not a complete measurement. SPF numbers are a measure of protection only against UVB radiation. The FDA does not require sunscreens to guard against UVA rays. Most sunscreens are designed for UVB protection only.
The SPF of a sunscreen is not directly linked to the time spent in the sun, but rather to how long it will protect against UVB radiation. In the summer, at 2pm, a person with a lighter skin tone will burn faster than someone with a darker complexion. It is crucial to apply sunscreen every two hours or more, depending on the amount of time you're exposed to.
The higher the SPF the better. SPF 15 protects against 93% UVB radiation, while SPF30 blocks 99.6 percent. A sunscreen with SPF 60 shields against 96% of UVB radiations, but you'll need a higher SPF if it is your tendency to burn easily.

The intensity of UVB Rays varies, thus the SPF of a product is determined by its effectiveness in protecting against UVB radiation.

The SPF number isn't an indicator of quality but rather a benchmark that determines the effectiveness of the sunscreen.
The SPF of a sunblock product is measured under artificial conditions. A sunscreen that has an SPF rating that is higher can provide more protection against UVA radiations, and may offer additional benefits. A product with a lower rating can't be called "broad spectrum" as it doesn't protect against UVB radiation. The SPF is a sign of the level of protection offered by the product. Before buying sunscreen it is essential to know the SPF and how it functions.
SPF is a labeling requirement set by the FDA for sunscreen products. However the higher SPF does not necessarily better for UVA protection than a lower one, and the same is true for SPF for a broad-spectrum product. SPF ratings can be misleading as sunscreens will easily wash off when exposed to water. In the end, the efficacy and substantivity of a product must be determined by in-vivo testing.
