Thank you for your responses. I had my whole body layered last week and she started with a 16j setting. Next time will be at 18. I was pretty pink, light red for a couple of days but I wasn’t burned. Also, on my sensitive areas which are my chest and face, she used a device that sucks the skin up in this clear plastic plate thing and she shoots the laser threw that. She said it was up to me if I wanted to use it or not, and of course I wanted it because the pain was so much less. This helped with the pain on my face it was a difference of night and day. She said the reason why it doesn’t hurt as much is because it pulls the skin or hairs away from the nerve endings. she said to come back in 3 weeks and she will touch up anything she missed for free. She spent a good almost 3 hours and did very good over lapping and I did not feel rushed at all. Much better than the place I used to go to that woulda go past a 12j setting. I’m happy!!!
