I use this wonderful device twice a day for about eight weeks. So slightly more often than the manufacturer recommends. Quite simply because I'm very impatient. After two to three weeks my skin is elastic and wrinkles (with me it was more fine lines) alleviated. Moreover, fade pigmentation spots (here but no miracles eewarten) and dark circles. To that end the face of contoured. Swelling decrease and deposits are mined. While it is, if you do as often as I used some time-consuming but worth the effort really worth. One only needs a little patience and discipline to achieve really good results!
