What is SPF? SPF stands for sun protection factor. This rating is used to determine how sunscreens block UVB radiation. SPF 30 blocks 96.7 percent UVB radiations, and SPF 50 blocks 98% UVB rays. Let's discuss SPF in more detail. Here are a few examples of SPF. What are the advantages of SPF?

SPF is a shorthand for Sunscreen Protection Factor. It protects against UVB rays.

Although SPF is a well-known measure of the protection a sunscreen provides, it is not a comprehensive measure. The SPF number is used to measure protection from only UVB radiations. Sunscreens aren't required by the FDA to also protect from UVA radiations, and the majority of sunscreens are designed for UVB protection, and haven't been given enough attention to other UVA rays.

The SPF of sunscreens is not directly related to the amount of time spent in the sun, but rather to how long it is able to protect against UVB radiation. A person with light skin is more likely to burn in the sunlight at 2pm in summer than a darker skinned person in the same climate. It is essential that sunscreen be applied every two hours or more based on the length of time you've been exposed.

The greater the SPF, better. SPF 15 protects against 93% UVB radiation while SPF30 blocks 99.6 percent. SPF 60 is able to block 96% UVB radiations. If you're prone to skin cancer, then you'll require a greater level of protection. The American Academy of Dermatology recommends using a broad-spectrum sunscreen of 30 or greater and avoiding the sun's rays during the hours of 10 a.m. until 2 p.m.

In addition to UVB protection, a sunscreen will also protect you from UVA radiation. SPF ratings only shield against UVB radiation. You should look for broad-spectrum sunscreens. Because they block both types UV rays, broad spectrum sunscreens provide broad-spectrum protection. When selecting a sunscreen, look for an SPF of at least 15 or higher.

The measurement of SPF isn't perfect. The test that is conducted on humans utilizes controlled conditions to determine the level of protection. The intensity of UVA Rays is fixed while the intensity of UVB radiations can vary. The intensity of UVB Rays can vary, and consequently, the SPF of the product depends on the effectiveness of protecting against UVB radiation.

SPF is a good indicator of the level of protection offered by sunscreens against UVB radiation. However it isn't a guarantee of protection from UVA. A broad-spectrum, broad-spectrum sunscreen that has an SPF between 15-30 is the best. The SPF numbers do not mean quality, but it is a standard that measures the effectiveness of sunscreens.

The SPF of sunscreen products is measured under artificial conditions. A sunscreen that has more SPF may provide greater protection against UVA rays and claim to provide additional benefits. For instance, a product that has a lower SPF rating can't be referred to as "broad-spectrum" because it only protects against UVB radiation. The SPF is a sign of the level of protection provided by the product. It is essential to understand SPF and how it functions before buying a sunscreen.

SPF is a labeling requirement set by the FDA for sunscreen products. However, a higher SPF is not necessarily better for UVA protection than a lower SPF and the same applies to SPF of broad-spectrum products. SPF figures are often misleading because sunscreens will easily wash off when exposed to water. In-vivo testing is only the best method to test the effectiveness and substantiality.
