I was going to do the cure for vampirism quest until I heard that your face goes back to the original template before you edited it. Is that true?

I felt the main quest was a bit lacking for some reason, but the side quest(namely the dark brotherhood) were beyond enjoyable. When I saw (SPOILER)Lucien Lachance killed and heard that Manimarco was back from daggerfall in the mages guild quests, I think I nearly fainted and had to remind myself it was just a game.
