Editor Quote: "After just four treatments, the difference is already remarkable. The 'before' image on the left and the 'after' image on the right clearly show the noticeable change. And I've barely made a dent in the box with plenty of treatments left," says our editor in her review of the Crest 3D Whitestrips.
