WebMD recommends applying antibiotic cream, covering a cut or scrape, and allowing the scab to form and fall off naturally to minimize scaring. Picking at a scab before it falls off opens the injury to bacteria and sometimes makes the scar larger.
The body forms scabs to protect the injured area while it heals, according to KidsHealth. The scab is a temporary crust. Underneath the scab, the skin is building bridges to close the injury. Once the skin heals, the scab begins to dry up and eventually falls off the area. Often the repaired area becomes a scar. However, scars are not always permanent. Some fade with time and become less noticeable. If scars are bothersome to an individual, medical treatments are available to reduce their size.
Even when people take care of a wound, they may still develop a scar, according to WebMD. Some individuals are more prone to form scars, and the location of the injury affects whether a scar forms or not. If the injury is in an area where the skin is constantly stretching and releasing, a scar is more likely to form. Sometimes superficial cuts leave scars. Seeing a doctor for treatment of deep injuries or cuts that have ragged edges often helps minimize scaring.
