How to heal something the fastest? neosporin?

Vaseline.: I know it sounds too simple but there was actually a study performed that compared neosporin with plain vaseline petroleum jelly to determine wound healing time and also risk of infection. Vaseline was actually just as good as neosporin. Also, a side note is that neosporin and polysporin (bacitracin and polymyxin) can produce an allergic contact reaction in some people!

Superfast healing: The real question is what not to do that slows down healing. Avoid using alcohol, peroxide, hibiclens, betadine, and bleach solutions. Inflammation ( red, hot, swollen, tender) is important to healing so anti-inflammatories (motrin, advil) are bad. Cover the area with a clean dressing changed every other day and protected from trauma. Antibiotics do not help healing unless it is truly infected.
