Skin wrinkles because it stretches like Silly Putty
Everyone is getting their skin with age, but real science behind the reason why it happens is more troubled than you expect.
Dermatologists generally cite factors such as genetics, UV damage and underlying pathological conditions. However, most evidence of the theories of the skin offspring come from studies that have used computer modeling to estimate how the dermal layer changes over time. Very few experiences involve validating theories with real skin samples. In this spirit, researchers at the Binghamton University of New York State University have decided to change this. Their results represent a conclusive and conclusive analysis in its kind offering a remarkably simple explanation of the way in which the lines of wrinkles are formed in the first place. According to their study published in the Mechanical behavior journal of biomedical materialsIt is generally a question of movement.
“It is no longer just a theory,” said the biomedical engineer and co-author of the study, Guy German, in a press release. “We now have difficult experimental evidence showing the physical mechanism behind aging.”
The German calls for the conclusions of his team a “Saint Grail” for skin mechanics, in particular in the context of an industry of several billion dollars dedicated to all kinds of dermatology regimes – many are more impossible than skin care.
“When I entered this area, it was one of my goals – can I understand aging?” Explained German. “Because if I watch television, radio, online, in stores, I am told 1000 different things about how to improve the health of my skin, and I want to know what is good and what is not. And so I thought I would jump until the end and try to understand it myself.”
To better understand the properties of the skin, the German and his colleagues recruited a group of volunteers aged 16 to 91. They then used a low -strength tenomage to stretch small strips of their skin to simulate the daily forces applied to the largest organ in the body. The results have clearly shown that the skin extends in one direction, it also contracts in the other direction. These contractions grow with age, forming wrinkles in the process. The German compared the dynamics to a popular elastic children’s toy.
“If you stretch the silly putty for example, it extends horizontally, but it also shrinks in the other direction-it becomes thinner. This is what the skin is doing,” he said. “As you get older, this contraction is growing. And if your skin is too contracted, it is buckled. This is how wrinkles are formed.”
There is a little more than the silly pĂątĂ©. According to the German, the mechanical properties of your skin become somewhat “bank” as you age and “things deteriorate a little”.
“It turns out that the skin extends more laterally, which causes the real wrinkles that are formed. And the reason why it exists first is that your skin is not in a stress-free state,” he said. âIt is actually a little stretched. So there are forces inherent in your skin itself, and it is the driving force towards wrinkles. â
For this reason, people with more physically active careers such as construction workers are likely to have older and wrinkled skin than office workers. But the German stressed that the team’s conclusions are not allowing anyone to win with regard to dermatological care.
Although mechanical stress can be the greatest influence on how wrinkles are initially developing, protection against the main problems such as the damage caused by the sun and hormonal imbalances will keep your skin healthy. It is not because the skin is smooth that it is immune to UV radiation, so be sure to continue to make up for you with SPF. Rided or not, your body will be better for that.
