What is SPF? SPF stands for sun protection factor. This rating is used to determine the extent to which sunscreens block UVB radiation. SPF 30 blocks 96.7% of UVB Rays, whereas SPF 50 blocks 98.6%. Let’s discuss SPF in more detail. Here are some examples. What are the advantages of SPF?
SPF stands for Sunscreen Protection Factor. It shields against UVB radiation.
Although SPF is a well-known measurement of the protection a sunscreen provides, it is not a complete measurement. The SPF number measures the protection offered by only UVB radiations. The FDA does not require sunscreens that protect against UVA radiation. The majority of sunscreens are designed for UVB protection only.
The SPF of sunscreens is not directly linked to the time spent in the sun, but to how long it is able to protect against UVB rays. A light skinned person will burn faster in the sun at 2pm during the summer months than a dark-skinned person will in the same setting. It is important that sunscreen is applied every two hours, or more, depending on how long you’ve been exposed.

Because they block both types radiations, broad-spectrum sunscreens provide broad-spectrum protection. When choosing a sunscreen ensure that the SPF is at least 15 or higher.
There are some limitations to the measurement of the SPF. To determine the level protection testing on humans, the test is done under controlled conditions. The intensity of UVA rays is fixed while the intensity of UVB rays varies. The intensity of UVB Rays can vary, and consequently the SPF of a product is determined by the effectiveness of protecting against UVB rays.
SPF is a good indicator of the protection offered by sunscreens against UVB radiation. However SPF does not guarantee protection from UVA. A broad-spectrum, broad-spectrum sunscreen that has an SPF range of 15-30 is the most effective. The SPF number does not indicate quality, but rather an indicator of the effectiveness of sunscreens.
The SPF of sunscreens is measured under artificial conditions. A sunscreen that has a higher SPF rating will provide greater protection from UVA Rays and may also offer additional advantages. A product with a lower rating cannot be described as “broad spectrum” as it doesn’t protect against UVB radiation. SPF is an indication of the level of protection the product can offer. Before buying sunscreen it is important to understand the SPF and topscosmetics how it works.
The FDA has set a labeling requirement for sunscreen products called SPF. However, a higher SPF is not necessarily more effective in UVA protection than a lower SPF and the same is true for SPF for a broad-spectrum product. SPF values can be misleading as sunscreens easily wash off when exposed to water. In-vivo testing is the sole method to test the effectiveness and substantiality.
