SPF is a sunscreen rating that shields against UVB radiation

While SPF is a widely used measure of how much protection sunscreens offer but it's not an exact measurement. The SPF number measures the protection offered by only UVB radiations. Sunscreens aren't required by the FDA to protect against UVA radiation, and the majority of sunscreens have been designed for UVB protection and haven't given much consideration to the other radiations.

The SPF of sunscreens isn't directly related with how much time they guard against UVB radiation. A light skinned person will burn faster in the sun at 2pm during the summer than a dark skinned person in the same climate. It is crucial to apply sunscreen every two hours or more, spf moisturiser for face based on the time of exposure.

There are some limitations in the measurement of the SPF. To determine the level of protection, the test on humans is conducted under controlled conditions. The intensity of UVA rays can be fixed and the intensity of UVB radiations can vary. The intensity of UVB radiations is different, and consequently the SPF of a product is based on its effectiveness in protecting against UVB radiation.

SPF is a reliable indicator of the level of protection offered by sunscreens against UVB rays. However, it does not guarantee protection from UVA. A broad-spectrum sunscreen with an SPF between 15-30 is the most effective. The SPF number isn't an indicator of quality, but rather a benchmark that determines the effectiveness of the sunscreen.

The SPF of sunscreen products is measured under artificial conditions. A product with an spf moisturiser for men higher can provide more protection from UVA radiation and claim to offer additional advantages. A product with a lower SPF isn't "broad spectrum" as it doesn't protect against UVB rays. The SPF is an indication of the protection offered by the product.
