GLO is the first and only at-home teeth whitening system that uses the professional elements of gentle heat and blue LED light to provide safe and effective tooth whitening results. GLO teeth whitening gel is thick, not runny, and stays in place (without the use of strips or annoying trays). Our system provides optimal yet gentle results - up to five or more shades lighter in five to seven days. Developed by NYC's top aesthetic practicing dentist, GLO has been proven safe and effective in multiple clinical studies.

You will see results with each application - whether you are using GLO Vial whitening gel alone or accelerating the formulation with light and heat from a GLO Device (which combines warming heat and LED light to accelerate whitening results). The more you GLO, the brighter your smile will get. This is thanks to our combination of gentle yet effective teeth whitening ingredients for use with blue LED light and gentle warming heat. GLO is clinically proven to whiten teeth an average of five shades over the course of one treatment (one treatment = five to seven days). Keep in mind that everyone's smile is unique, and there are many factors involved that affect teeth whitening, including age, genetics and lifestyle. For that reason, some people's teeth will whiten faster; some will take more time.

GLO whitening gel is specially formulated to be sensitivity free. It contains safe and effective teeth whitening ingredients, is free of alcohol and carbamide peroxide, and is designed to stay put on your teeth and off your gums and soft tissue. The vast majority of GLO users do not experience any sensitivity while using GLO.

Whitening your teeth and keeping your smile bright is a little like coloring your hair: maintaining your results requires maintenance. Your individual maintenance program depends on a number of factors, including lifestyle, age and original shade. We recommend first completing a full GLO whitening treatment (which is five to seven days) to achieve your desired shade. After that, maintain your teeth whitening results with one day of whitening each month (three back-to-back applications), followed by another five-to-seven-day full GLO whitening treatment after six months. That said, if you notice that your teeth are darkening sooner (or you feel like they could use some brightening), simply whiten with our GLO whitening gel, available in a pack of three convenient GLO Vials or more, as soon as you feel you need to - until you achieve your desired shade. Additional five- to seven-day treatments with your preferred GLO device can also be safely repeated until your desired result is achieved.

After your first full treatment (five to seven days), you can use GLO whitening products once per month, performing three or four back-to-back applications in one day. When it comes to how you can keep your teeth white, you can incorporate a full GLO whitening treatment into your routine every four to six months. If you feel more frequent full treatments are needed, please consult your dentist. Also remember a few easy teeth whitening tips at home, such as avoiding coffee, tea and tobacco. If you're unable to change your habits, GLO Vials are ideal for use: just brush them on in between whitening treatments.

No. You control your shade of white and the teeth whitening results. You can achieve the ideal shade that is just right for you and tailor your GLO results to your preferences.
