Fasting can help skin and scars definitely. But I just want to encourage people not to go straight into water fasts. It's very tough. I tried it and lasted only 48 hours and then ate crap and felt really bad and never wanted to fast again haha!!
Anyway I think a good idea is to do things like eating REALLY clean for a while before fasting, then doing a few short fasts (24-72hrs), all the while not expecting your scars to just disappear but knowing that your helping your body to begin healing them.
Also maybe trying liver flushes and enemas and stuff. Read all about that kind of stuff on curezone.com.
You're body is capable of doing incredible healing if we allow it to. I really believe this even though I haven't personally experienced it. Damn, if people can overcome terminal illness through diet, I'm sure we can get rid of our scars in gentle ways!
Aghhne, duffq- good luck with your fasts, i'll be checking back here to see how ye are!
