Did not work at all. I have pale white skin and dark brown hair. Some areas are corse, some medium and some thin. It didn’t work in any area dispute regular use. I thought it had worked on the thin and maybe reduced the medium but after four months I stopped use and the hair came back after a few weeks and is back on a quick growth cycle. I was going to return the device but I thought maybe with more time it will work. Don’t be fooled. Return yours asap if you don’t see the results you want. More time will not make a difference.
