Treatments can help, but not cure, keloids (scars)

You may have seen pictures of tribal warriors from Af rica with intricate scars all over their bodies. This process is known as scarification. It is where an incision is made in the skin with a sharp instrument in such a way to cause the scar to take a certain shape. Scarification has been done for thousands of years. When these cuts heal, they form raised scars, which are known as keloids.
