Dermatologists tout sunscreen for its ability to prevent signs of aging and protect against skin cancer. But now, new research suggests a measurable benefit of slathering on sunblock with as little as SPF30: a reduced risk of melanoma.
“Sunscreens are known to prevent skin from burning when exposed to UV sunlight, which is a major risk factor for melanoma. However, it has not been possible to test whether sunscreens prevent melanoma, because these are generally manufactured as cosmetics and tested in human volunteers or synthetic skin models,” principal investigator Christin Burd, assistant professor of molecular genetics at The Ohio State University, said in a news release. “We have developed a mouse model that allows us to test the ability of a sunscreen to not only prevent burns but also to prevent melanoma.”
