This myth remains a myth, in my opinion. Their testing has been thoroughly critiqued here on EcoModder. You should be highly skeptical of their results.
Also, when you go to the "Fastskinz" websight (http://www.fastskinz.com/) it's just a bunch of Blah Blah Blahdidi Blah and absolutly no FACTS....or Real Test Results. Reminds me of the claims made by people on TV trying to sell dietary supplements or Juicers or Water Ionizers......I hope like hell none of you bought a water ionizer.
