I agree with the OP. I had Dermabond for both of my surgeries and it has an excellent healing response. The skin is much less traumatized since there are no stitches or sutures to remove. Mine came off completely within 2-3 weeks both times (I also could not fight the urge to pick at it). :D
It will be tender for a while. I especially noted it with hot water in the shower or scraping my shirt across it. Just be patient and it should heal up very nicely. I am 6 months out from my last surgery and you can hardly see my scar and it is quite recessed into my neck.
If after a couple of weeks you still have severe redness and/or any type of lumps/bumps with discharge, I would see your surgeon. You should already be on antibiotics though that would fight off infection.
Hope you get to feeling better soon!
