New research highlights how repeated trauma to delicate skin areas can lead to long-term scarring, replacing natural, flexible tissue with rigid collagen. The process, known as fibrosis, increases the risk of permanent dermal damage with each injury, altering the skin’s structure. Scientists warn that confined or frequently irritated skin may be particularly vulnerable to this progressive condition. Understanding the mechanism could help in developing treatments to prevent or mitigate chronic scarring.
“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 ...
