A bright-white smile is sexy, sure. But the means by which it’s achieved are decidedly, well, not. Dentist visits can be costly and crazy-painful, since the high intensity of bleaching agents can cause sensitivity. And at-home strips require time and fuss. GLO Science combined the best of both to create a light-powered at-home device that’s both pain- and fuss-free—and offers results almost instantly.

The kit consists of blue-light infused mouthpiece on which the user is to spread whitening gel (which comes included in the form of ten “single-serve” vials) before switching to “on.” Pop it in, kick back, and let the light do its thing. Unlike other devices, it’s totally hands-free, so you can get back to work, Snapchatting, you name it. A single eight-minute session visibly brightened (yes, really!) and after five simultaneous days of use, the results rivaled that of in-office treatments.
