SPF stands for Sunscreen Protection. It protects against UVB rays.

Although SPF is a well-known measure of how much protection a sunscreen provides, it is not a precise measurement. SPF numbers are a measure of protection against only UVB rays. The FDA does not require sunscreens to shield against UVA radiation. Most sunscreens are made to provide 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 is able to protect against UVB rays. A person with light skin will be more burned in the sun at 2 pm during summer than a dark skinned person in the same setting.

The intensity of UVA radiation is fixed, whereas the intensity of UVB radiations is variable. The intensity of UVB radiation varies and the SPF of a product will be based on its capacity to protect against them.

Although SPF is a good indicator of the protection offered by sunscreens against UVB radiation, spf moisturiser face it does not guarantee protection from UVA rays. A broad-spectrum sunscreen body moisturiser with spf an SPF between 15-30 is the most effective.

The SPF of a sunblock product is measured under artificial conditions. A sunscreen with a higher SPF can offer greater protection from UVA radiations and claims to offer additional benefits. For instance, a product that has an SPF rating that is lower cannot be described as "broad-spectrum" because it only shields against UVB radiations. The SPF is an indication of the protection offered by the product. It is crucial to know about SPF and how it functions before buying a sunscreen.

SPF is a labeling standard set by the FDA for sunscreen products. A higher SPF doesn't necessarily mean greater UVA protection than the lower one. The same applies to broad-spectrum products that contain SPF. SPF ratings are often misleading because sunscreens will easily wash off when exposed to water. In the end, the efficacy and substantivity of a product will only be confirmed through in-vivo tests.
