What Is Broad Spectrum Sunscreen?

What is “broad spectrum” sunscreen? Remember SPF is all about burning, but the sun does a lot of other stuff to you like destroying the stuff in your skin that keeps it firm and looking good. That stuff is largely caused by ultraviolet A (UVA) and ultraviolet B (UVB) rays, something not really measured when testing for SPF. Broad spectrum on the label means that the sunscreen also blocks those UVA and UVB rays. So, If you care about minimizing wrinkles and blotchy skin while you’re outside, always use a broad spectrum sunscreen.

Burnd does all of the above by using zinc oxide, not the thick white stuff lifeguards used to put on their noses, but a revolutionary type that is transparent, but still blocks a ton of both the burning and aging rays. In fact, one of burnd’s founders actually came up with this idea years ago. Now to get a high SPF using only zinc oxide, even the really special stuff, the formulation has to be kind of thick and usually pretty oily. So, burnd uses a combination of zinc oxide with some of the more traditional ingredients and the result is the best of both worlds. It’s a great feeling, high performance sunscreen based on zinc oxide and the absolute minimum amount of other sunscreens.
