Women's Skin Ages Faster Than Men's

Women's skin loses collagen at faster rates than men's, resulting in women's skin aging faster than men's, according to researchers in Germany.
Researchers at Friedrich Schiller University in Jena and the Fraunhofer Institute of Biomedical Technology in St. Ingbert tested a new laser-based technique directly on the forearms of 18 patients, measuring the collagen/elastin factor. The team was also able to obtain images of tiny swaths -- one-fifth of a millimeter wide -- of the proteins' fibrous matrices, showing the physical appearance of the dermis, the white lower-layer of skin that gets exposed in deep abrasions.
In a healthy 35 year old, some areas can appear like the skin of a 25 year old, and others like that of someone who's 50, said Johannes Koehler, a dermatologist at Friedrich Schiller University and study co-author.
On average, both the collagen/elastin factor and the physical appearance of the network showed a clear dependence on the patients' age, but the dependence appeared to be sex-dependent, with women's skin losing collagen at faster rates than men's, according to the study published in the journal Optics Letters.
