According to a study from Binghamton University, skin aging collagen fibres grow more closely packed together as they absorb more ultraviolet (UV) radiation, increasing stiffness and making tissue more difficult to tear.
The study examined how UV radiation may change the microstructure of human skin and was published in the Journal of the Mechanical Behavior of Biomedical Materials. Collagen, the fibrous protein that holds tissue, tendons, cartilage, and bone together throughout our bodies, was discovered to be severely damaged.
The outer stratum corneum, or top layer of skin, was the subject of earlier studies that were built upon in this recent study. The scientists evaluated full-thickness skin samples before and after different amounts of UV exposure in a recent study.
“Performing a mechanical stretch test on the skin is one technique to describe its material properties. The more readily something expands, the more compliant it is; the harder something is to stretch, the stiffer it is. According to main researcher Abraham Ittycheri, a doctorate student at the university, “My experiment was to see what the isolated effects of UV light would be and compare it with a scenario where a skin is not exposed to UV light.”
“We don’t want to instil a fear element in this place that says ‘don’t go outside in the sun. However, spending a lot of time in the sun might toughen your skin and increase your chance of developing cancer, the expert continued.
Since our skin is the biggest organ in the body and the first line of defence against microorganisms and other external threats, methods to care for and even enhance it are unquestionably advantageous. Ittycheri stated that any interference with the skin’s natural functions would be exceedingly hazardous and harmful to our way of life as a whole. That doesn’t even touch on the aesthetic side of things, where having bad skin might make someone feel less confident about themselves.
