Four Phases of NORMAL Skin Wound Healing

4 Phases of Normal Skin Wound Healing

Acute wounds normally heal in an orderly and efficient manner and progress smoothly through the four distinct but overlapping phases of woundhealing: hemostasis, inflammation, repair, and remodeling (Figure 1). The process of wound healing is complex and involves a variety of specialized cells, such as macrophages, fibroblasts,and epithelial and endothelial cells. These cells interact with each other and with the extracellular matrix.
