What is SPF? SPF stands for sun protection factor. This rating is used to determine how sunscreens block UVB rays. SPF 30 blocks 96.7% of UVB radiations, and SPF 50 blocks 98.6 percent. Let’s discuss SPF in more detail. Here are some examples. What are the benefits of SPF?
SPF is the abbreviation for Sunscreen Protection Factor. It shields against UVB Rays.
Although SPF is a well-known measurement of the amount of protection sunscreens provide but it’s not a precise measure. SPF numbers measure the protection offered by UVB radiation. Sunscreens aren’t required by the FDA to protect against UVA radiations, and the majority of sunscreens are designed specifically to provide UVB protection, and haven’t been given much attention to the other radiations.
The SPF of a sunscreen is not directly linked to the 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 2pm during summer than a dark skinned person in the same situation. It is vital to reapply sunscreen every two hours or more, depending on the duration of exposure.
The greater the SPF, better. SPF 15 protects against 93 percent of UVB rays, while SPF 30 blocks 99.6 percent. A sunscreen with SPF 60 protects against 96 percent of UVB radiation, but you’ll need a higher SPF if you are prone to burn easily. The American Academy of Dermatology recommends that you apply a broad spectrum sunscreen with an SPF of 30 or more , and stay out of the sun from 10 a.m. to noon.
A sunscreen must not only protect against UVB radiation, but also UVA radiations. While SPF ratings are only effective against UVB radiation, you must also look for broad-spectrum sunscreens. Because they block both types radiations, broad-spectrum sunscreens provide broad-spectrum protection. Look for sunscreens with an SPF of at least 15 when choosing the sunscreen.
The measurement of SPF isn’t 100% accurate. The test on humans uses controlled conditions to determine the level of protection. The intensity of UVA radiations can be controlled and the intensity of UVB radiations may vary. The intensity of UVB radiation varies and the SPF of a product will depend on its ability to guard against UVB rays.
SPF is a good indicator of the level of protection offered by sunscreens against UVB rays. However SPF does not guarantee protection from UVA. A broad-spectrum sunscreen with an SPF between 15-30 is the best. The SPF number isn’t a measure 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 that has greater SPF is likely to provide more protection from UVA rays and claim to offer additional benefits. For example, a product with an SPF rating that is lower can’t be referred to as “broad-spectrum” because it only protects against UVB radiation. The SPF is an indication of the protection offered by the product. Before purchasing sunscreen products it is crucial to know the SPF and how it works.
SPF is a labeling requirement set by the FDA for sunscreen products. However an SPF that is higher not necessarily better for UVA protection than a lower SPF, and the same is true for spf in moisturisers SPF for a broad-spectrum product. Furthermore, SPF figures can be misleading as a sunscreen can easily wash off when exposed to water. In-vivo testing is the sole method to assess the effectiveness and substantiation.
