In a study published this week in the Annals of Internal Medicine, Australian researchers found that people who regularly apply sunscreen are 24% less likely to show signs of increased aging.

They make a recommendation: lather up and do it every day. Without fail.

“Protecting yourself from skin cancer by using sunscreen regularly has the added bonus of keeping you looking younger,” Adele Green, one of the study’s authors.

“And the study has shown that up to middle age, it’s not too late to make a difference.”
