Let’s get the horror stories out of the way first, because they’re fun. Do not, under any circumstances, use superglue on a deep, jagged, or dirty wound. If you can see fat, muscle, or bone—that’s a job for stitches, not a glue stick. Gluing a dirty wound is like putting a band-aid over a mudslide; you’re just sealing in bacteria, dirt, and your own poor life choices.
Also, keep that tube far, far away from your eyes, mouth, or any mucous membrane. I cannot stress this enough. One flick and you’ll be explaining to an ophthalmologist how you “just wanted to fix that eyelid hangnail.” Also, never use it on an animal. Your cat does not need a cyanoacrylate toupee, no matter how many times he scratches the sofa.
