Wound healing is the natural physiological reaction to tissue injury. It is the normal biological process in which the human body achieves through four precisely and highly programmed phases: hemostasis, inflammation, proliferation, and remodeling. If interference with one or more of these phases of the process happens, due to many different factors, improper or impaired wound healing occurs. It involves a complex interplay between numerous cell types, cytokines, mediators, and the vascular system.
Hemostasis: The first phase of healing happens within seconds or minutes of getting a wound. The body focuses on stopping the bleeding first and preparing for the second phase of healing.
Inflammation: Is the second phase of wound healing. It starts to form a blood clot or scab. Scabs create a barrier to keep bacteria and germs out of the wound.
Proliferation: Phase three of wound healing or rebuild mode. The body sends oxygen-rich blood cells and collagen to help form new skin. This stage may look red and raised. Maturation: The final phase in wound healing. During this stage, the body strengthens the area, softens scars, flattens, and fades. Maturation time varies due to the severity of the wound.
