How to heal a cut faster?

Rest, don't pick.: How long a cut takes to heal depends on where it is on your body, and how deep it is. If it is in an area of movement, like over a joint or is widened when you use the muscles under it, then movement will keep it from coming together. Clean it with mild half strength soap, and cover with Bacitracin twice a day. Don't pick. Avoid moving the affected part ( a splint may be required).
