以前的印象. 開放性傷口癒合之後, 經過三個月的皮膚強度可以恢復60-70%
不過這篇寫的是 80%. 僅節錄其中一小段.
Maturation
The final stage of wound healing is the maturation phase, and includes collagen cross-linking, remodeling, and wound contraction. Initially, fibroblasts synthesize type 3 collagen which is thinner than mature, type 1 collagen is abundantly found in healthy skin. During the maturation phase, type 1 collagen replaces the type 3 collagen found in granulation tissue, and a scar forms. This increase in type 1 collagen correlates with the increased strength of wounds seen 4 to 5 weeks after healing. A wound will regain 80% of its original strength 3 months after injury. Unfortunately, attaining the full strength of the skin before the injury is impossible. [3]
