What Is SPF and Broad-Spectrum Sunscreen?

Chances are, you’ve probably heard that you need to wear sunscreen every day  – even on cloudy days and indoors. But did you know that 80% of UV radiation can actually penetrate through clouds and UVA rays have the ability to travel through glass? Everyone needs a broad spectrum sunscreen!

Why do you want a broad-spectrum sunscreen?

The FDA’s definition of broad-spectrum sunscreen is sunscreen that can protect you from the sun’s harmful ultraviolet A (UVA) and ultraviolet B (UVB rays). These damaging rays can cause sunburns, premature aging, and skin cancer.

Skin Cancer is the most common cancer in America with over 5 million cases diagnosed each year. Because 1 in 5 Americans will develop skin cancer, it’s important that we are aware of the signs, risks, and prevention measures.

what is SPF?

Basically, think of SPF as a ‘sunburn protection factor.’

Sometimes the SPF numbers can be confusing, but all you need to now is the SPF number tells you how much of the UVB light is being filtered out.

For example, an SPF 15 filters out 93% of the UVB rays and a SPF 30 will filter out 97% of the UVB rays. It is important to understand that there is no sunscreen that can filter out 100% of the sun’s UVB rays. Sunscreens provide a screen, not a block! Make it a habit to apply 15-30 minutes prior to going outside and don’t forget to reapply every 2 hours.
