CA specifically for skin is called Derma-Bond. Don't bother trying to find it because it's the same thing we use on our models just sterile.I first learned about using CA on cuts at a gig ofmine, one night between sets my bassist's finger tips were so raw he was putting Krazy glue on them!!( I playthe Drums so no need for it there) He said he was doing it for a while with no issues. I have used it on minor cuts and especially my cuticles around my finger nails when they rip ever since. As far as the CA tips ,go on e bay you can get 100 for about 5 bucks and you wonthave to worry about them for a long time. Just trim the end to fit on the CAbrand bottle you use and cut off the small end if they get clogged. I use a small T-Pin to seal it up after use and Never had anProblem. My 2 cents!!
