Now there is a study that shows the anti-aging benefit of using a sunscreen everyday.
In a study published in the Annals of Internal Medicine, Australian researchers showed that the use of sunscreen on a daily basis significantly reduced the signs of skin aging.
The study involved 903 people ages 25-55 and was funded by the Australian government.
After four and a half years, the study participants who applied sunscreen everyday showed a 24% reduction in skin aging, as measured by lines and coarseness of the skin, than the participants who applied sunscreen only on an intermittent basis.
So, find a sunscreen you like, use it each day, and in 20 years you will be very happy you did.
