Sunscreen and Aging

by Berkeley Wellness  

Daily sunscreen use slows skin aging, even in middle-aged people, according to a well-designed Australian study in the Annals of Internal Medicine.

It’s clear that consistent sunscreen use reduces the risk of skin cancer, but this is the first proof in humans that it also protects against photoaging—the wrinkling, dark spots and sagging skin caused by the sun’s ultraviolet rays.

More than 900 white people ages 25 to 55 were either instructed to use broad-spectrum sunscreen (SPF 15+) diligently every day or simply told to use sunscreen at their discretion (it would have been unethical to tell them not to use sunscreen at all). After four years, the daily sunscreen group had 24 percent less skin aging, on average, than the other group.
