GLO Science Teeth Whitening Gel – 6% Hydrogen Peroxide – Clinically Proven, Fast & Safe for Sensitive Teeth – Includes 10 Gel Vials & 1 Lip Care

Works just fine

I bought these refills and use the original mouth piece from several years ago. I continue to get great results.The original instructions says to use for 4 eight minute sessions. These new instructions say 3 eight minute sessions. I’m not sure if the gel or the mouthpiece is more effective for them to change this.In any case, this still works as it always has. I am pleased with the gels.

My dentist sells 4 of these vials for $60. I got 10 vials for $48 on Amazon Prime day. Still more affordable even at full price. GLO Whitening works and doesn't hurt my sensitive teeth

I purchased the system about 5 years ago from my dentist and I ❤️ the convenience. So I am happy to have what is needed for whitening at 🏡.

Works great

Love this product

The cinnamon tooth whitening gel has less gel in tubes. Its consistency looks like it's old & drying out. Plus blue caps pop off when trying to squeeze in mouth guard. Plus a lot of bubbles in cinnamon W/blue caps which tells me gel is breaking down. Please note mint w/white caps does not have bubbles in tubes. These are all new not opened yet. My only complaint.

This gel will whiten your teeth over several applications of 7 - 15 minutes each session. Apply gel onto teeth fron gel applicator. Place LED light mouthpiece in mouth and turn on with attached battery device. Leave on for 7 - 15 minutes each session. Teeth slowly whitened with each application. It took about one week with several 7 - 15 minute applications each day to fully whiten teeth. Battery device is rechargeable and hangs around your neck so you can move about while whitening process is on. Much easier to use then strips which always fell off while in use. The gel packs are made of a hard plastic and a bit difficult to squeeze but they will empty all the gel.
