Scientists from the University of Binghamton have found that skin aging is connected not only with collagen's loss, but also with changes in its response to stress. The results of their study were published in the magazine of "Mechanical Behavior of Biomedical Materials" (JMBBM).
The team studied the skin samples of people from 16 to 91 years old. Using a tension measuring, a device that measures the reaction to the material stretching, scientists model the everyday skin tensions.
It turned out that when the skin stretches in one direction, it is compressed in the other direction, the effect that intensifies with age.
"Compression with age is growing, and the texture is deformed, causing folds. In the past, this conclusion could only be achieved through hypotheses and computer modeling, "Hermann said.
It was previously believed that wrinkles arise from various factors, including genetics, ultraviolet radiation and various diseases. Early models assumed that the dermis (layer of skin that contains collagen and elastin) is deteriorated over time, but there are no direct evidence.
Scientists have said that the study opens new opportunities for the creation of targeted creams affecting mechanical properties of the skin, as well as to develop more accurate methods of diagnosing its biological "mechanical age".
