Wart or Scar Tissue on my Face? How Do I Get Rid of This?

I used to have a medium sized brown wart on my face (cauliflower shape & visible root) The steps I took: - Doctor diagnosed it as a wart, froze it & it grew back - Tried tons of home remedies until successfully burning it off with Apple Cider Vinegar (which I continued using) - My dermatologist now cannot tell if I have a wart or not This is a flesh colored bump now that doesn't grow, isn't contagious, and doesn't change shape. I want it gone for good! :( HELP!
