According to a German study using a new laser-based technique to measure damage from sun exposure and aging, women's skin ages faster than men's. I always thought this was just women gossip but apparently, there is some science to it after all.

The study, published in Optics Letters, a journal of the Optical Society of America, was based on a new technique in which doctors shine pulses of infrared laser light to look at the deeper layers of the skin and measure aging.

To save you grabbing the medical dictionary, all you have to know is that the images found that women lose collagen faster than men. Collagen is the stuff responsible for the strength of the skin that causes wrinkles when damaged.

"The dependence appeared to be sex-dependent, with women's skin losing collagen at faster rates than men's," according to the researchers from Germany's Freidrich Schiller University in Jena and the Fraunhofer Institute of Biomedical Technology in St. Ingbert.

Authors of the study said this test might one day help in testing anti-aging cosmetic products as well as in the study of skin diseases that affect the collagen structure.
Maybe one day L'Oreal will come up with a cosmetic that prevents aging of the skin....face-lift doctors will go broke :)
