Just read about MSM making scars dissapear after taking for some time.
(for external application: GMSO) [GMSO along with the vitamin E might do since GMSO (MSM) opens up the cell wall]
For some reason I think I also read about cayenne having the same effect. (makes sense since cayenne increases circulation)
(Sorry I can't get the links at the moment, kind of in a rush today...)
BTW: MSM: internally GMSO: external only
