in my personal experience ~ your mileage may vary ~ neosporin or bacitracin applied first will help keep the friction to a minimum, will keep the area moist and help prevent cracking of the new skin, and will help combat infection.

after many years of the dry-it-out crowd i've become a convert to the moist method.
