This is a scam. There is no laser, like they advertise. They have a fake LED lamp from China that is sold on Amazon for roughly $100, and unbranded whitening gel, probably of the same quality. The service is performed by a girl who isn't properly trained and doesn't know what she is doing. They take the "before" pic with the phone without flash and the "after" pic with a flash, to show you that the "after" pic is lighter. But it is not. The process should consist of four 15-minute sessions, and for each session new gel needs to be applied. The "technician" girl sent me home after just one session. I guess, she was too lazy to apply the gel a second time. When I complained that I saw no results, they brought me in again for 2 more sessions. In the end, I still don't see any results, and this is very disappointing. To my complaint that the procedure yielded no results, the dentist offered me veneers... SMH
