What is a scab?
A scab is a form of cover that protects the skin against blood loss, debris and infections. A scab is formed after an injury at a particular site on the body. The coming together of the platelet blood cell at a site of injury helps to increase blood clotting. When these cells begin to work, they keep germs at bay and also form a hard crust like layer. This crusty layer is called a scab. The appearance of a scab is temporary and lasts for about two to three weeks only, then the new skin is revealed.
Scabs on the lips mostly result from a trauma experience on the lips. These trauma may be in the form of wound or injury. The various causes, treatments and right steps to take to hasten the healing process will be discussed extensively.
