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.)
It wears off in 3-4 days.
