Mehmet Oz, MD, Cardiology, answeredPicking a scab is a bad idea. Think of these hard, reddish patches on the skin as nature's bandage. Scabs form over wounds to protect against germs while your skin heals. Picking a scab can leave a wound unprotected. Let a scab fall off naturally, which will usually occur in about a week or so, when healthy skin has reformed over the wound.
