Researchers finally know Why our skin wrinkles over time – And the silly putty can help explain it.
Scientists at the University of New York Binghamton say that experimental evidence shows that this is a process similar to the stretch of a hooded sweatshirt or a favorite overuse t-shirt. Essentially, aging skin extends in one direction, contracts in another, then collapses. As they get older, the contraction increases, resulting in the formation of The skin folds and folds.
“If you stretch the silly putty, for example, it extends horizontally, but it also shrinks in the other direction – it stops thinner,” explained in an associate professor of biomedical engineering, Guy German, in a statement. “This is also what the skin is doing.”
The wrinkles begin to appear after the age of 25, according to the Cleveland clinic. Scientists have long believed that the skin wrinkles due to genetics, the effects of the disease and the damage caused by the sun. As you get older, your Skin cells are replaced at a slower ratecausing the end of the outer layer of the skin and form wrinkles. Lines in the face, including Front and frowning linesare largely out of our control, because they are caused by repeated muscle movements.
Previous studies, using calculation models, have also shown changes in mechanical properties such as elasticity and structure of the central layer of the skin during aging. The layer, which contains elastin and collagen proteins, is the house of hair follicles, blood vessels and sweat glands. So far, these changes had never been proven experimentally.
“When I entered this area, it was one of my goals – can I understand aging?” said German. “Because if I watch television, radio, online, in stores, I am told 1,000 different things about how to improve the health of my skin, and I want to know what is good and what is not.”
To achieve these conclusions, the German and his team used a low force tenant to stretch seven tiny bands of people of people between 16 and 91 years old, simulating the forces that the skin naturally experiences. Tenomage tests the maximum force that a material can resist while being pulled or stretched before breaking. The skin was collected by elective surgery or fabric from corpses.
They found that the skin has a set of mechanical properties when you are young. As it gets older, things become a little “bank”, noted the German.
“Things deteriorate a little, and it turns out that the skin extends more laterally, which causes the real wrinkles that are formed,” said German. “And the reason why it exists first is that your skin is not in a stress-free state. It is actually a little stretched. There is therefore forces inherent in your skin itself, and it is the driving force towards wrinkles.”
Research, which did not explain how these forces could be interrupted, was recently published in the Mechanical behavior journal of biomedical materials.
Of course, there are other things that we know how to affect the skin that can contribute to appearance over time. Spend too much time outside can cause a nasty sun burnas well as aging the skin prematurely with the same effect as naturally aging.
“If you spend your life working outside, you are more likely to have older and wrinkled skin than those who are office workers, for example,” warned German.
