how long it take for a busted lip to heal
Rating Newest Oldest. Best Answer: Apply an ice pack for 10 minutes where it punctured the skin on your lip to reduce swelling. You can also apply a very thin layer of Polysporin or Neosporin to help it heal faster. It should take 3 to 5 days to start looking better depending on how severe your cut is. If its bleeding and won't stop, you need to go to an urgent care for stitches. Source(s): medic.
