Wounds are breaks in the skin that can heal in healthy people
Normally the skin is capable of healing wounds in a remarkable process that begins with clotting of the blood. This clot generates signals for inflammatory cells to come and help “clean up” and fight potential infections. Very quickly after that skin cells start rebuilding and come together to close the wound leaving behind a scar which can take months and even years to reach its final size.
However, in a chronic wound, this process does not work properly leading to wounds that are very slow to heal or do not heal at all.
