Took more than an hour for receiving no effect. Salon had problems with the light machine and kept trying to fix it, at some point I though I would have to just go back home to another part of Malta because of this. When they compare your teeth shade with a scale in the beginning, they don't give you a mirror but just pick a number themselves, only at the end it's possible to look and they say it moved so many numbers on their scale when in reality I have not noticed any difference. Unfortunately was a waste of money.
