[ad_1] When skin absorbs more ultra violet (UV) radiation, the collagen fibres in it become more tightly packed together, leading to increased stiffness and tissue that is harder to break, according to the research from Binghamton University.  The study, published in the Journal of the Mechanical Behavior of Biomedical Materials, explored how UV radiation can alter the microstructure of human skin.  They found that collagen, the fibrous protein that binds together tissue, tendon, cartilage and bone throughout our bodies get particularly affected.  This new study builds on previous research that focused on the outer stratum corneum, the top layer of skin.  In the new study, the team compared full-thickness skin samples before and after various levels of UV exposure.  "One way to characterise the material characteristics of skin is by conducting a mechanical stretch test on it. If it stretches very easily, it's relatively compliant, but if it's much harder

"I wondered if you'd ever had anybody look at it?"
