It is very common for patients to think they need to put Neosporin on their incision site after surgery or following a trip to the ER that required stitches.  It is not true, and can actually be bad to put any type of antibiotic ointment on an incision.  Incisions should be kept dry to allow the body’s normal process of repairing the skin edges.  When any type of ointment, be it Neosporin or evenVaseline, the skin edges can become moist and actually open up or dehisce.   The best scenario to allow your incision to heal adequately on your foot is to keep it dry.  Foot incisions typically take 10-21 days to heal.  The foot takes longer on average to heal over average becuase it’s blood supply is not as abundant as others areas on the body, especially the face.
