Certain laceration characteristics cause abnormal hypertrophic scarring
the verdict
SUPPORTED
the evidence backs this
confidence 97/100
Evidence consistently shows that specific laceration and wound characteristics—such as depth into the reticular dermis, mechanical tension, and local microenvironment alterations—are key drivers in the development of abnormal hypertrophic scarring.
