(CNN) -- It turns out sunscreen does more than protect you from cancer and painful sunburns -- it offers a boost to simple vanity. A new study finds that regular sunscreen use protects against photoaging: the wrinkling, spotting and loss of elasticity caused by exposure to the sun's ultraviolet radiation. While they may not be shocking, the findings -- from Australian researchers -- are the first to quantify sunscreen's anti-aging properties. More than 900 participants were followed for four years. Some were told to use sunscreen daily and instructed in proper use, including re-applying sunscreen after being outside for a few hours, after going in the water or after sweating heavily.

Skin changes were measured through a technique called microtopography, in which researchers made sensitive silicone impressions of the back of each participant's hand. link
