Colgate Optic White ComfortFit LED Teeth Whitening Kit, Hydrogen Peroxide Teeth Whitening Gel Kit, Helps Remove 10 Years of Stains, Enamel Safe, Includes Whitening Pen and Flexible LED Light

It's very convenient, and my teeth are much whiter.

This worked pretty good!

I’ve seen moderate whitening so far—nothing dramatic, but definitely noticeable! The best part is it doesn’t irritate my sensitive teeth (huge win). The LED is comfy, and the pen’s super easy to use.

I have used the kit 4 times - I skipped a day - I forgot. Here's what it's really about - it's not what I expected. 1. You have to have your phone to charge it. You can also plug it into a charging outlet - it does not have it's own power source like most. You do the light for 10 mintues: You turn it on and it runs for 5 minutes and beeps to let you know its half way - it runs another 5 mintues and beeps and shuts off. None of that is in the documentation. I kept taking it out at the 5 minute beep. 2. It's a paint/film, it is not a gel that you rinse off after. 3. It's hard to get an even layer with the applicator. 4. You can't tell how much product is on the applicator and if you're using enough. 5. Sometimes you get it right (I guess) with a thin layer you can't really feel after it dries. 6. Other times you get a big glob and you can feel a gritty layer on your teeth. 7. The film is recommended to stay on your teeth overnight for best results. 8. The pen liquid has peroxide and the blue light just accelerates the peroxide chemical process to bleach your teeth. 9. The gel to use going forward is expensive. After the pen is empty, I think I'll just brush as usual, then brush on a small amount of peroxide and use the light. Only a few times a week. Too much peroxide is not good and will burn and damage. Maybe I'll just use a peroxide toothpaste and then the light. 10. Right now, I have what feels like nail polish on my teeth and it's crumbly and flaking off periodically, causing me to have to spit it out - which is annoying. But my teeth are noticeably lighter. I just won't be using the liquid pen anymore. 11. The mouth piece, however, is the best I have ever come across, so I would like to keep using it. You just can't hold it in your mouth like other blue lights and walk around and do stuff - you have to take the power source with you.

I really liked this whitening system, especially the light. Give yourself a month to see full results, some might see it sooner than other but the first session you will see improvement.

The LED light stops working within seconds of putting it in my mouth. Tried multiple times. Also the pen applicator is weird and the brush doesn't apply the whitening gel consistently. Most importantly: IT'S NOT RETURNABLE. You will have to go to Colgate themselves to ask for a refund.

I recently tried the Colgate Optic White ComfortFit Teeth Whitening Kit, and I’m thrilled with the results. The convenience of this kit is unmatched – it even works with both iPhone and Android devices, making it incredibly versatile. The LED light and whitening pen combination made the process straightforward and comfortable. After just a few uses, I noticed a visible difference in the whiteness of my teeth. What’s more, I didn’t experience any sensitivity, thanks to its enamel-safe formula. The instructions were clear, and the entire process was hassle-free. Overall, I highly recommend the Colgate Optic White ComfortFit Kit to anyone looking for an effective and user-friendly teeth whitening solution. It’s definitely worth the investment for a brighter, more confident smile!

Don't seem to even lift surface stains, whitening toothpaste does a better job.

If you use it for 10 days as instructed, you will see a difference, but the pen doesn’t work well or last long. There’s no good way to clean the pen without it ending up a mess.
