Scientists 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 long-term damage where the skin loses its natural elasticity. Research suggests this cumulative effect worsens with each successive trauma, potentially leaving permanent structural changes. Understanding the mechanism could help in developing treatments to prevent or reduce scarring in high-risk situations.
“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 ...
