What is the scar formation process and how does it affect the healing of wounds?

Scar formation is the body's natural response to repairing damaged skin tissue. When a wound occurs, the body produces collagen fibers to close the wound, resulting in a scar. The scar tissue is often different in texture and appearance from the surrounding skin. While scars help to heal wounds, they can sometimes cause discomfort or restrict movement depending on their size and location.
