Ooh, my time to shine! Wounds heal better and minimize scarring when they're kept moist. I like either Neosporin and an occlusive film dressing (like Tegaderm), or a hydrocolloid dressing by itself, like these:

If the wound is small and very superficial, like a paper cut, keeping it clean & dry is fine.
