yes, works great for small cuts and for cracked nails. Just make sure the wound is shut all the way so the chemical in it isn't inside your skin. Doesn't band-aid have a super glue for that?
Another one is new skin. When I was young, we were camping and I stepped on an axe...got a big cut, not deep, but my uncle pulled that out of his pocket and put it on it. It never got infected and there is no scar.
