Scabs can heal as quickly as within a few days if you do not pick or scratch at them, according to WebMD. Other methods that make the healing process go more quickly are supplementation and proper care.
Scabs protect a wound from dirt and germs while new skin grows underneath, explains WebMD. Scabs may itch, but scratching one too early may introduce bacteria in the wound and cause it to heal more slowly. The scab falls off on its own when the new skin under it forms fully. Supplementing with antioxidants such as vitamin C, bromelain, rutin and grape seed extract has shown to speed up healing.
According to MedlinePlus, people with diabetes are likely to have slow-healing wounds and may need to see a doctor for treatment of the condition. Poor blood flow due to clogged arteries is another reason why wounds may heal slowly. Heavy alcohol abuse and smoking make wounds heal more slowly. Getting enough sleep, reducing stress and eating well all speed up the healing process.
Medications such as corticosteroids, nonsteroidal anti-inflammatory drugs and chemotherapy drugs can slow healing, according to MedlinePlus. If a scab is very slow to heal, a doctor may better care for it.
