How to get rid of facial warts besides using ointments or freezing them?

Does anyone know how I can get rid of my facial warts? I've had a few (they look like pimples that you can see only when you look closely at my face)of them for a few years and they haven't budged, even though my Doctor said they would go away by themselves.I have had them frozen by a dermatologist and not only was it painful but it left unsightly scarring, plus the warts have all returned with a vengeance. I have tried countless cream and ointments and nothing works.I have a healthy diet and I am otherwise healthy.What can I do to get rid of them besides what I have already tried.I have always had clear skin rarely having pimples even when I was a teenager, so getting warts feels like I have been having spots for years now and I can't help but feel self conscious about them.I want them gone, can anyone help?
