Gentlelase with Cryogenic Cooling


I’m seeing mixed reviews on this device. I’m interested in having my neck hair removed. I was told it would take at least four treatments at $150 per treatment to totally remove the hair. Time between treatments would depend upon how quickly the hair regrew–I was told that four weeks would be typical. I have not yet had a test patch done, but am somewhat scared of the pain. I have brown hair on light skin. Does this sound reasonable? How much does it hurt?
