Whether a scrape heals with or without a scab does not affect the healing time or the amount of scarring.

Blood vessels open in the area, so blood can bring oxygen and nutrients to the wound. Oxygen is essential for healing. White blood cells help fight infection from germs and begin to repair the wound. This stage takes about 2 to 5 days. Tissue growth and rebuilding occur next. Over the next 3 weeks or so, the body repairs broken blood vessels and new tissue grows. Red blood cells help create collagen, which are tough, white fibers that form the foundation for new tissue. The wound starts to fill in with new tissue, called granulation tissue.
New skin begins to form over this tissue. As the wound heals, the edges pull inward and the wound gets smaller. A scar forms and the wound becomes stronger. As healing continues, you may notice that the area itches. After the scab falls off, the area may look stretched, red, and shiny. The scar that forms will be smaller than the original wound. It will be less strong and less flexible than the surrounding skin.
Over time, the scar will fade and may disappear completely. This can take as long as 2 years. Some scars never go away completely. Scars form because the new tissue grows back differently than the original tissue. If you only injured the top layer of skin, you will probably not have a scar. If a scab cracks, dislodges, or otherwise fails to keep bacteria out, they can enter the wound and cause a skin infection. The scab itself is made of dead cells and cannot become infected.
It is the wound itself that becomes infected. People may be able to tell when a wound underneath a scab is infected by how the scab looks, as well as the presence of some other symptoms. Symptoms that the wound under a scab is infected include the following:. If the scab appears to be getting bigger after several days instead of staying the same size or getting smaller, this can also indicate an infection. A common misconception is that if a scab is black instead of deep red or brown, the area is infected.
This is not the case. If a person suspects that they have an infected wound underneath a scab, the first stage of treatment is to make sure that the wound is clean and dry. Current guidelines suggest that the best ways to keep a wound clean are as follows:. As well as practicing proper cleansing techniques, people can take nonsteroidal anti-inflammatory medications such as ibuprofen or acetaminophen to reduce wound pain and swelling. However, people should always consult a doctor before starting any new medications.
A doctor should provide specific post-care instructions as to how to treat the wound moving forward. If the scab seems to be increasing in size instead of decreasing, a person should see their doctor.
