Review (5/5): Highly recommend
I am shocked at how well this works. I have tried other whitening treatments but have never really seen a noticable difference (given my impatient nature). These pictures are from right before the first treatment (freshly brushed) and right after the fifth treatment. It is a 7 shade difference according to the card that comes with the kit. I'm going to do a few more treatments before going into maintenance mode, but I'm so happy with the results already that I felt I needed to share!
