Researchers warn that repeatedly injuring the same delicate skin areas—such as through friction, pressure, or minor trauma—can lead to long-term damage by replacing natural, flexible tissue with stiff scar collagen. This process, known as traumatic dermal scarring or fibrosis, progressively reduces skin elasticity and function over time. The findings highlight how even seemingly minor or repeated injuries may accumulate, potentially causing irreversible changes in affected areas. Experts suggest this could have implications for conditions involving chronic skin stress or medical procedures requiring repeated access to sensitive skin.
“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 ...
