Scar tissue is a type of fibrous tissue that forms as part of the healing process after an injury or surgery. When the skin or other tissues are damaged, the body produces collagen to repair the area. This collagen forms a scar, which may appear different in color and texture compared to the surrounding skin. Scar tissue can develop in various parts of the body, including the skin, muscles, and organs. While it helps to close wounds and restore function, it may also lead to complications, such as reduced flexibility or discomfort. In some cases, treatments like physical therapy or surgery may be needed to improve the condition of scar tissue.
