SPF, Broad Spectrum, UPF… What do they mean?

June 25, 2015

Here at Mott 50 we are often asked questions about the difference between terms such as SPF, broad spectrum, UVA & UVB. Well, this post is here to shed some “sunlight” on these really great questions!

When shopping for sun protective products make sure you look for the SPF sign, SPF stands for “sun protective factor” which indicates the level of protection against sunburns. When trying to decide how much protection you need SPF 50+ is the best for total coverage.

Although SPF is very important for sun protection, make sure you pay attention to labels that are marked “broad spectrum.” Ultraviolet A & ultraviolet B also known as UVA & UVB rays.  Only broad spectrum ensures both are blocked. UVA rays have skin damaging impact such as causing early skin aging, wrinkling, and tanning.  The effects are not seen immediately.  On the other hand, UVB rays are the reason for sunburns, which show up within a few hours of sun exposure.

When shopping for sun protective clothing, look for the ultraviolet protective factor or UPF label. Sun protective clothing with a UPF of 50+ blocks out 98% of UV radiation, which includes both UVA & UVB rays. Clothing also covers the surface of your skin keeping you from having to reapply or guess.

To gain all the sun protective benefits look for SPF products with the “broad spectrum” label and sun protective clothing with the UPF label. Now go out and have some safe sun fun!
