When you say superglue, do you mean an off the shelf superglue that you would pick up at a hardware or craft supplies store? Did it just dissolve on its own after X number of days?
I've used off-the-shelf superglue on cut fingertips where I couldn't get bandages to stay. I believe it's also commonly used in place of stitches where you don't want the scarring that stitching would cause (e.g., parts of the face.)
Yes I used some old super glue lying around the house. I was worried at first because even though I pinched it together, a large amount of glue went into the gash and so I was left with a hard shell over the wound and a clump of glue in the gash. But after 4-5 day the shell peeled off and the clump of glue fell out and even though the cut was completely through the skin, it healed perfectly. It was like the skin bitter together under the lump of glue until the clump was pushed out. I’m no doctor and only know about the glue because my mechanic brother in law uses it for every cut and gash he’s ever had.
