sun exposure is the no. 1 (and 2 and 3) cause of aging of the skin. sun-smart behavior is essential. avoid midday sun never go to a tanning salon wear sun-protective clothing when possible and use a high spf sunscreen and reapply it every two hours when you are out. if you would like the look of a tan try a sunless tanner. these have come a very long way and are safe.
