Researchers warn that repeatedly injuring the same delicate skin areas can heighten the risk of severe scarring, as flexible tissue is gradually replaced by rigid collagen. The process, known as fibrosis, leads to permanent changes in the skin’s structure, potentially causing long-term damage. Studies suggest this cumulative effect may worsen with each successive trauma, altering how the skin functions and heals over time. 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 ...
