Did my 41st laser session yesterday and I asked the dermatologist (basically her assistant) to show me the settings of the machine. The machine is an old alexandrite (candela). The settings she used on me are 10J and 20mm. The max Joule settings go up to 14J. I guess these settings are way to low, right?
There is your answer. You were robbed of your money by a poorly trained, clueless technician. You were being under-treated 41 times at full price with no guarantee. She goes home with a salary and you're stuck dealing with unwanted hair 3 years down the line.
My first session was 16j on 18mm spot and rest were going up to 20j. She obviously doesn't know anything about laser hair removal if she is sitting there doing 41 treatments with no results and doesn't think anything is wrong.
