Wound healing is the body's natural process of repairing damaged skin or tissue. When an injury occurs, the body responds by forming a clot to stop bleeding and protect the area. This is followed by inflammation, where white blood cells fight off any potential infection. Over time, new tissue forms, and the wound gradually closes. As healing progresses, the body continues to strengthen the area. Collagen, a protein that helps support skin structure, plays a crucial role in this phase. Eventually, the skin may return to its normal appearance, although some wounds can leave scars, depending on the severity of the injury.
