How do you get a crust?
What Causes Scab? The crusts form as a defense against infection, blood loss, and debris. When you have a scrape or cut, the platelets — or cells in the blood clot — begin to clot to stop bleeding and prevent excess fluid from leaking out. As the blood or wound dries, it forms the hard layer of a crust.

When you remove a scab, you leave the wound underneath vulnerable to infection. They also increase the time it takes for the wound to fully heal. Repeated scab removal can also lead to long-term scarring. 30
What happens if you keep removing a scab?
New tissue forms under the protective surface of the crusts. The body repairs damaged blood vessels and the skin makes collagen (a type of white, tough protein fiber) to reconnect damaged tissue. When the healing work is done, the scab dries up and falls off, leaving the repaired skin and often a scar.
