New research highlights how repeated trauma to delicate skin—such as frequent injuries or medical procedures—can lead to long-term scarring and tissue stiffening. The study explains that each new injury in the same area compounds damage, replacing natural, flexible skin with rigid scar tissue over time. Understanding this process could reshape approaches to wound care and scar prevention. Experts suggest the findings may have implications for conditions involving chronic skin trauma.
“And repeatedly traumatizing the same confined area of thin skin increases the cumulative risk of traumatic dermal scarring (fibrosis), replacing flexible dermal tissue with stiff scar collagen that ...
