GLO

🦷 MAIN FEATURES
Our third favorite option is from GLO. This one costs a pretty penny, but it surely delivers exciting results. GLO utilizes advanced continuous warming technology that safely and quickly catalyzes hydrogen peroxide (the whitening chemical). This, in turn, brightens your teeth almost immediately, so it doesn’t take very long to start noticing the results. According to the brand, GLO provides 8 times faster warming for optimal results and it also stays warm between sessions to preserve heat while you’re reapplying gel. It also has a long battery life which should suffice for at least 17 applications on a single charge.

DESIGN AND EASE OF USE
GLO promises to whiten your teeth by 12 shades in as little as five days. This is likely because the use instructions suggest repeating your 8-minute session three times. First, you would need to apply lip balm to protect your lips (lip balm is included in the package), then apply the whitening gel to your teeth, insert the mouthpiece, and press the on button. The session lasts for 8 minutes and GLO strongly recommends repeating the process three more times immediately. This can be the reason why GLO is said to be so effective, however, you might run out of your whitening gel supply pretty soon.

VALUE
GLO teeth whitening kit is not exactly the definition of cheap. While it certainly offers great features, the price is a little bit high. Besides, it is estimated that you would use all whitening gel packs in five days, so buying more would only increase the total cost of this device. Another slight drawback is that you would need to repeat the 8-minute session three times, a total of 24 minutes per one full session which is quite a lot. So, even though GLO is quite effective, there are certain things that you should carefully consider before choosing this option.
