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

I've used this for about 2 years and it's much easier than whitening strips. Doesn't work miracles, but definitely takes away coffee and cola stains.

A great friend told me the secret to her beautiful white teeth and smile, and I have been using this product for 3 years now. GLO Classic Gel Vials are so easy to use and effective even after one application, and doing it twice makes a brighter impact. Kidding aside, I have tried many other teeth whitening products, or the expensive dentist ones, and I have to tell you that this product outperforms them all. No strong chemical taste or smell, and easy to apply. To use, simply apply a thin layer of the gel to your teeth using the provided applicator, and then activate the gel with or without the GLO device. It's that simple!

This works well, but you should know that I use these gels with the glo device. I also should mention that I have never used anything else to whiten my teeth so I cannot compare it to anything else that is out there. This whitens my teeth to a believable white color and is not painful to use.

Good price for product

This was my wife and I first time using this product. We noticed a difference the first time and now we’re on day four. You can definitely tell the difference. I will purchase this product again.

it’s working dentist recommended

I purchased the glo whitening system from my dentist which included whitening gel tubes that lasted about a year. I needed to reorder these but the refill kit was hard to find on Amazon. Eventually I was able to order them. I like the gel which is easy to apply to my teeth and use with the whitening mouth guard. Each pod lasts more than a month. The gel doesn’t irritate my sensitive teeth and whitens several shades lighter.

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.

Good product. Easy to use. Works pretty well. Noticeably whiter after 10 consecutive uses

I have the mouthpiece that lights up from this brand so I love these for when I need refills. Amazing price. They are cheaper here than in “beauty” stores. One thing though, make sure you take the tube apart when you think it’s empty. There is a lot more product you can get out. I have very VERY sensitive teeth and all other whitening products cause pain and sensitivity to even air, but I’ve never felt any pain or sensitivity with these. As long as they make these, I will buy them. 10 vials will last you a long time. When I use these I can usually get several shades whiter after about 5-6 days.

1 am 73 almost gave up on teeth heavy coffee drinker ,,,stains gone in 2 days with this stuff amazing,,,one vile last you 2 weeks doing every second day,,, ,,box last for long long time

Glo works very well. I believe the new gel kits are a big improvement over the original kits - amount of gel, taste, better applicator. My teeth are much whiter. The price is not cheap, but the effect is worth it.

I have used this company’s system of whiten teeth since it was first released, many years ago. It was an expensive kit with a mouth piece, plugin, a looped charged to hang around your neck to plug the mouthpiece in. It also contained tubes of gel to protect and moisturize lips & inner mouth as well as the whitener in circular pods to squeeze and brush on the teeth. It worked very well for me. The last batch of whitener I recently bought came differently packaged and different instructions. They supposedly made it easier to whitener the teeth. One got the refills in supposedly an easier circular pod to squeeze and brush on the teeth. And now one did not need to use a light. Just brush on anywhere and go about your day. As always I put the whitening formulation on my teeth after carefully applying the protective gel over the inside and around the lips. I did not use a light and found my teeth were not whitening as before and the solution was burning the skin inside my mouth & lips despite the protective gel. I then put the light mouthpiece in my mouth to distance the solution from the skin. Despite reapplying the gel to protect each time it burned my mouth so bad I had to stop. Even after cleaning all the solution out of my mouth & teeth it was still burning. The gum on the opposite side of my upper lip when flipped over was very red and irritated. The next morning upon waking my mouth was still burning & sore. When I looked in the mirror I was shocked. My entire top lip was so swollen. It looked like it had been injected with several tubes of filler it was so huge. There was a deep red patch inside that looked like a burn. It took 3-4 days for my swollen lip to be normal, And inside my mouth is still a scar from that burn. It has not returned to normal. I have no answer as to the why this other formula reacted to burn my mouth other than the formulation had to be significantly changed in order for it to work without a light. I intend to contact the company for some answers. It was a great product to use at home at your convenience before the change. I cannot in good faith recommend it without a Caution Warning. I never thought this could have happened after using this product faithfully for at least 20 years.
