I would say that with persistence you could cure it.
I didn't have the persistence to use it every day for a long time. I may have used it everyday for about 2 weeks, then sporadicly after that. After years of breaking out almost weekly, I have now been sympotom free for over a year. Except, there have been times of stress when I had a mild outbreak. Back to the Terminator to chase it away.
The Terminator changed my life for the better. Do it!! Yes, yes!!
