So far, so good. Here in Dallas there is a wonderful alternative to the high cost of these non-surgical cosmetic treatments--an institute where they teach them. Because it is a school, you can either choose to have an instructor (regular cost) or students (super low cost) do the procedures. Yes, I know there is a risk factor, and some procedures may not be as suitable for this kind of thing, but frankly there were 3 students doing the eMatrix while the instructor paid close attention--I had face, neck & chest done--and each of them was just as good as a typical technician you would pay far more for. I used the "B" setting since I have sun damage, melasma, and skin laxity. It was a predictable experience, with the "rubber band" type stings and immediate heat response but nothing I couldn't handle.
I realize I am only one day out, and even though everything looks even (eMAtrix has distinctive grid marks so you can see where the RF energy was used) I probably won't know for sure until another week or two. I will update then, but wanted to say for now that I am very pleased and especially with the awesome deal--super professional yet friendly place - gotta love it!
