This at-home, two-step innovation whitens teeth up to eight shades — in just 30 minutes. Here's how it works. First: You apply whitening serum to your teeth. Next: Insert the light into your mouth where it shines on your teeth for about 10 minutes, then beeps, and shuts off. Last: Immediately repeat the steps twice more for dentist-quality whitening, without sensitivity, every two weeks for positive pearlescence!
