Scar Say: skar A scar is a mark left on your skin from a cut or wound that has healed. You're most likely to get a scar if there is a lot of damage to the skin or the edges of a cut are too far apart to heal properly. You can help prevent scars by keeping germs out by cleaning and covering your cuts and scrapes. And don't pick at those scabs!
