What is the difference between “Physical Barrier” and “Chemical” Sunscreens?
Physical Barrier Sunscreens (like Badger’s) form a film on top of the skin that reflects or scatters UV light. Most physical barrier sunscreens contain either zinc oxide or titanium dioxide. We choose micronized zinc oxide for our sunscreens because we feel it is the safest & most effective option – and has been used successfully for hundreds of years. UV light is divided into three wavelength bands: UVA, UVB and UVC. UVA and UVB are the two that reach the earth and Physical Barrier sunscreens are effective at blocking both. By the way, our sunscreen is in a spectrum of protection that also blocks UVC light. So this would be a good option for astronauts and pilots, who are also exposed to UVC – no kidding! Chemical Sunscreens differ from physical barrier sunscreens as they absorb UV rays before they can do any damage. Usually, single chemical ingredients protect against either UVA or UVB, but not for both. So for broad-spectrum protection, you would need to choose a chemical sunscreen
