Sunscreen is known to be one of the best defenses against skin cancer. Now researchers believe it can slow signs of aging too.
A study out of Australia compared people who use sunscreen randomly and those who use it daily. After four-and-a-half years, the regular users had 24 percent less aging.
Ultraviolet rays cause damage to your skin anytime you're in the sun.
"Regular use of sunscreen had an unquestionable protective effect," said Dr. Richard Glogau, a clinical professor of dermatology at the University of California, San Francisco. He wasn't involved with the Australian study.
"They [consumers] can get a two-for-one with sunscreen. They can do something that will keep them healthier and also keep them better-looking," Glogau added.
Dermatologists recommend using sunscreen daily but also limiting time outdoors during peak UV hours between 10 a.m. and 4 p.m.
"I'm fond of telling people that if they start using sunscreen on a regular basis and don't do anything else, over a period of time they'll see an improvement in the appearance of their skin," Glogau said. "It's never too late."
