Women's skin ages faster than men's

TORONTO: Women's skin ages faster than men's, says a German study using a new laser-based technique to measure damage from sun exposure and aging.
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 deeper layers of the skin andmeasure aging. The imaging of collagen and elastin, whose degeneration causes wrinkles and loss of smoothness, found that women lose collagen faster than men.
"The dependence appeared to be sex-dependent, with women's skin losing collagen at faster rates than men's," said researchers from Germany's Freidrich Schiller University and the Fraunhofer Institute of Biomedical Technology.
Collagens are a group of proteins in the dermis, the connective tissue layer of the skin, and are responsible for the strength of skin. The human body makes a lot of collagen in youth but production declines with age.
Currently, dermatologists who want to examine a patient's collagen network in the dermis have to remove a sample of tissue and look at it under a microscope.
Authors of the study said this new non-invasive test might one day help test anti-aging products and the study of skin diseases that affect collagen structure.
