It was a factory-type treatment, and even though I made a reservation, I had to wait for an hour and a half, and there were a lot of people . As the event was taking place, I was only treated with the in-mode treatment on my double chin area, and it was so painful that I wanted to scream. I didn't think I could do it twice, so I only got the treatment once, but it wasn't effective at all. A small, yellow bruise will last for a few days.
