A keloid is a shiny, smooth, raised formation of scar tissue. Keloid formation is theorized to occur as a result of an imbalance between an increased synthesis of collagen and extracellular matrix and decreased degradation of these products. Keloid scar formation arises from a disorganized fibroproliferative collagen response that extends beyond the original wound margins because of excessive production of extracellular matrix (ecm).
But A Keloid Is An Over Growth Of Scar Tissue.
Despite treatment options for keloid scars including medical and surgical therapies, such as intralesion. How do keloid scars form? Less commonly, keloids may form in places where the skin has not had a visible injury.
