Women age faster than men!

It may seem that women make much ado about nothing at the first signs of wrinkles, but they do have reasons to get paranoid, as a research has demonstrated that women’s skin ages faster than men’s.

Researchers have now devised the first non-invasive test to measure skin aging. This new laser-based technique images the fabric of the deeper layers of the skin, combining methods for imaging collagen and elastin, whose degeneration causes the appearance of wrinkles and the progressive loss of skin smoothness.

The technique measures relative amounts of collagen and elastin by a single factor, which can be positive or negative, like temperatures. Higher values of the factor correspond to higher collagen content, and to lower elastin content. Previously, each of the imaging techniques had only been tested on tissue extracted from live patients.
