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% UVB rays, and SPF 50 blocks 98% UVB rays. Let's discuss SPF in more detail. Here are some examples. What are the advantages of SPF?





SPF is a sunscreen rating that shields against UVB Rays





While SPF is a widely used measure of the amount of protection a sunscreen provides, it is not an exact measurement. SPF numbers indicate protection against only UVB radiation. The FDA does not require sunscreens to protect against UVA radiation. Most sunscreens are made for UVB protection only.





The SPF of sunscreens isn't directly proportional to the amount of time they shield against UVB radiation. A person with light skin is more likely to burn in the sun at 2 pm during the summer than a dark skinned person will in the same setting. It is vital to reapply sunscreen every two hours or more, depending on the amount of time you're exposed to.

A sunscreen with SPF60 protects against 96% of UVB radiation, but you'll need a greater SPF if it is your tendency to burn easily.

Broad-spectrum sunscreens provide broad-spectrum protection as they block both types of radiation. Make sure to choose sunscreens with an SPF of at least 15 when selecting a sunscreen.





There are some limitations in the measurement of the SPF. To determine the degree of protection tested on humans, the test is done under controlled conditions. The intensity of UVA radiation is fixed, whereas the intensity of UVB Rays fluctuates. The intensity of UVB Rays can vary, and consequently, the SPF of the product depends on the effectiveness of protecting against UVB rays.

The SPF of sunscreens is measured under artificial conditions. A sunscreen with a higher SPF rating can provide better protection against UVA rays and may have additional advantages. A product with a lower rating cannot be described as "broad spectrum" as it doesn't protect against UVB rays. SPF is an indicator of how much protection the product can offer. Before purchasing sunscreen products it is crucial to understand the SPF and how it works.

The same applies to broad-spectrum products with SPF. Furthermore, SPF figures can be misleading as a sunscreen can easily wash off when exposed to water. In the end, the efficacy and substantivity of a product can only be established through in-vivo testing.
