Clinical Studies & References

At GLO Science, we've noticed that when you have safe and effective at-home teeth whitening products and devices that are clinically proven to work, people also take notice. We're proud to provide our customers with these clinical studies, references, peer-reviewed articles and other materials. We hope that you'll take a moment to check out these references, including studies that have utilized GLO Science teeth whitening products, tested their efficacy and measured them up with other leading at-home teeth whitening products.

Our patented products and devices were invented by New York City's top practicing aesthetic celebrity dentist, Jonathan B. Levine, and are now used in thousands of dental practices around the country. GLO Science has changed the way professionally whitened teeth are achieved. In addition, we've offered our at-home best teeth whitening products that actually work, made with safe home teeth whitening ingredients. Our patented GLO Science products, devices and methods, which use gentle warming heat and LED lighting, amplify your teeth whitening results in a relatively short period of time.

When you incorporate GLO Science products and devices (such as GLO Lit and GLO Brilliant) into your oral health routine, you'll enjoy a brighter smile and a healthier mouth. The active hydrogen peroxide ingredient in our patented GLO Vials teeth whitening gels can help reduce the germs in your mouth - improving overall gum and mouth health as well as reducing your chances of gingivitis.

With decades of experience in clinical dentistry, GLO Science is an industry leader in teeth whitening and oral care technologies. For more information about GLO Science, such as more about our GLO Vial formulation or how to use our products, check out GLO Learn!


GLO Science teeth whitening and oral care technologies and formulations are based on science, decades of experience in clinical dentistry, and expertise on smile beauty and oral health.
