SPF is an SPF rating for sunscreens that protect against UVB rays
Although SPF is a well-known measure of the amount of protection a sunscreen provides but it’s not a precise measure. The SPF number is used to measure protection from only UVB rays. Sunscreens aren’t required by the FDA to protect against UVA rays, and most sunscreens have been designed to provide UVB protection, and haven’t been given much consideration to the other radiations.
The SPF of a sunscreen is not directly related to the amount of time spent in the sun, but rather to the amount of time it shields against UVB radiation. A light skinned person will burn more quickly in the sun at 2 pm during summer than a dark skinned person in the same setting. It is imperative to apply sunscreen every two hours or more, based on the length of time you’ve been exposed.
The more powerful the SPF, better. SPF 15 protects against 93% UVB Rays, while SPF30 blocks 99.6 percent. SPF 60 blocks 96% UVB radiation. However, if you’re prone to skin cancer, you will require a higher level of protection.

The measurement of SPF isn’t completely accurate. To determine the level of protection tested on humans, the test is carried out under controlled conditions. The intensity of UVA rays can be fixed, while the intensity of UVB radiations can change. The intensity of UVB radiation varies so the SPF of a product will be based on its ability to protect against UVB rays.
SPF is a reliable indicator of the protection offered by sunscreens against UVB radiation. However it doesn’t guarantee protection from UVA. A broad-spectrum sunscreen with an SPF between 15-30 is the most effective. The SPF number is not an indicator of quality but rather a benchmark that determines the effectiveness of a sunscreen.
The SPF of sunscreen products is measured under artificial conditions. A sunscreen product that has greater SPF ratings can provide better protection against UVA radiation and could offer additional advantages. For example, a product with an SPF rating that is lower is not a “broad-spectrum” because it only protects against UVB radiations. SPF is an indication of the level of protection the product provides.
