I work in an urgent care and we use a product called Dermabond. It is not CA but close to it. Because it is medical grade you can't just buy one but a whole box and unlike CA its microbial for several days. That way people are less likely to get C-Diff or MRSA. It is also much more flexible than CA. The CA cracks with movement while this stuff is almost rubbery. CA won't hurt you but it really doesn't do the job like this stuff will. Then again for a couple hundred bucks less who would complain about CA!! We also put this stuff on top of Sutures to seal them up better.
