Sunscreen Works Against UVB Rays: Study
May is melanoma awareness month. As you get ready for summer, a recent study gives you another reason to stock up on sunscreen.
Researchers at Ohio State University exposed mice to UVB rays, and found that a sunscreen with SPF 30 or higher reduced their chance of melanoma by 80 percent. The brand wasn’t important; simply wearing the sunscreen was what mattered.
“They all worked,” lead researcher Christian Burd says. “Now, for the first time, we have a mechanism to say, ‘yes, this sunscreen can protect against melanoma.’ and we hope that we can now use that information to develop better, smarter sunscreens.”
However, the study exposed the mice to only UVB, not the entire spectrum of rays provided by sunlight.
