Two words -- balder dash.

Every backcountry freak I know -- from the kayakers in the Grand Canyon to the top of the Rockies -- has used the OTC version of cyanoacrylate for at least 10 years, and we all carry it as part of the first aid kit.  Before the derm & plastics docs figured it out ... along with ERs and the pharmaceutical industry (which markets a super-spendy version that's exactly the same as Superglue)

Last time I used it was a year or two back when my climbing partner decided to split his eyebrow with an ice axe.  It was still bleeding two hours later when we pulled into the Twin Cities and I suggested driving to the ER for a few sutures.  He didn't have insurance (or $600.00 cash) so we stopped at an all-night CVS for a tube of Superglue & a bottle of alcohol. 

The only area where I'd expand on Jurate's reply is the matter of technique.  After cleaning the wound out, the trick is to grab the opposing skin edges with a forceps, pull the skin together, and run a bead of superglue across the top surface.  Cyanoacrylate is blood-soluble, so it looks a little funky (sort of a pink froth), but if you're careful the results are better than stiches.

This is what it looked like before we knew how deep the cut was:



I'll admit to being a little edgy about the cosmetic aspects -- like, I didn't want to glue his eyebrow together all goofy and take the blame for the rest of my life -- but it didn't even scar (at least, nothing you can see).

And I only put that photo up 'cause it grosses out Susanne.
