Well, i hope that it's not just the typical stuff that i've seen being sold on the internet then. Granted, I have no clue what this guy is selling... i hope it is a cure. I guess of course there is only one way to find out, buy his book. I hope you aren't dissapointed.
Otherwise, I just want to say that I've "suffered" back and forth with Acne for the longest time; both as a teenager and an adult. I've read tons of information and forums and learned a lot. I posted a message the other day about what has helped me; and I was almost at the point of thinking that I'd always have this problem.
I have read about Zapping; but haven't tried that yet.
best of luck to you, I really hope that if you do buy the book that it gives better information than is posted for free on this website.
