If a wound re-epithelizes within two weeks there will be minimal collagen deposited and there will be no scar. Any injury does not become a scar until the wound has completely healed; this can take many months, or years in the worst pathological cases like keloids. To begin to patch the defect a clot is created; the clot is the beginning process that results in a provisional matrix. In the process the first layer is a provisional matrix and is not scar. Over time the wounded body tissue then over-expresses collagen inside the provisional matrix to create a collagen matrix. This collagen over expression continues and cross-links the fiber arrangement inside the collagen matrix, making the collagen dense. This densely-packed collagen, morphing into an inelastic whitish collagen[14] scar wall, blocks off cell communication and regeneration and as a result, the new tissue that is generated will have a different texture and quality than the surrounding non-wounded tissue. This prolonged collagen-producing process results in a fortuna scar.
