About GLI GLI
The kit and its add-ons
Everything starts with the Sparkle Booster Teeth Whitening Kit. This set typically bundles a whitening device, gel pens and the accessories for a full course. Once the gel runs low, the Sparkle Booster Gel Refill tops it up. The Teeth Whitening Device is also sold on its own, and the Remineralization Gel Pen is designed to support enamel health. The packaging is compact, so the kit travels well.
What the brand claims
GLI GLI describes its products as dentist-approved and gentle, with formulas meant to limit the sensitivity whitening can cause. Some customers report a visible shade change in about six days, though results depend on your starting shade and how consistently you use it. Tutorials and usage guides sit in the Support section of the site.
