Yeah thanks for the info. The only problem here is I have a skin reaction around my wrists and ankles from zapping. An itchy, itchy red rash which takes days to clear. I would like to zap on an area that needs attention on my face but I did week ago, I got this bright tiny dark red marking like a round spot (not acne) came up on my cheek. I had to cover it up which a coverstick for a week to it gradually disappeared. This could be what you term a burn mark or some other reaction, don't know which though. What did u use (contact pad or similar) on your jaw when you zapped that area?? Or did you place the wriststap on that area?....<>
