How does your body repair bruises?

When you bruise, small blood vessels under the skin break, allowing blood to leak into surrounding tissues. The body repairs the bruise through a process that involves inflammation, where immune cells clean up the damaged area, followed by the reabsorption of the leaked blood. Over time, the body produces new cells to replace the damaged tissue, and the bruise changes color as it heals. Typically, bruises fade from red to purple, then yellow or green, as the blood is gradually broken down and absorbed.
