Disclaimer: I am not a doctor. Never take any advice from me. I am insane.
Now, what I do is disinfect a razor blade and run the corner over that spot. Then I use a pimple-popper thingie to press the little ant egg (yes, that’s the correct term according to me) and it pops right out.
It will look bad for a few days, so be sure to do this just before a date, job interview or family photo session.
Bonus medical info: I use the razor and rubbing alcohol to remove skin tags from my underarm, too. I paid a doctor once, then discovered I could easily do it myself.
Again, never follow my suggestions.
