Cut or injured skin heals itself automatically. If someone cuts themselves and starts to bleed, the blood soon forms a clot that stops further bleeding. The clot dries to form a scab, which prevents germs from entering the damaged skin. Beneath the scab, new skin cells grow across the wound, and when the skin is healed the scab drops off.
