Debriding a wound isn’t quite the same as peeling off a scab. Worse, actually, as they’re removing foreign objects and dead tissue mostly by wiping it away. This does prevent as much scar tissue from forming but is mostly to protect from infection and promote the remaining healthy tissue’s growth.

Source: not a doctor, our son was hit by a car and we had to do this for the abrasions. First at the wound treatment clinic but then again later at home.
