Not worth anything!

Concerning you cannot find the % of the hydrogen peroxide that's in this. Only states it's in there for ingredients

[This review was collected as part of a promotion.] Product does work! I have been using it for two weeks & have noticed a difference! The reason I didn’t give it a perfect 5 it because I definitely am a strip girly. I like being able to just put them in and go this you do have to let dry for 60 secs before closing mouth and sometimes it’s a little gummy. But other than that it works!

[This review was collected as part of a promotion.] This product began to work instantly on my teeth. I never took pictures but the results are awesome. I am a smoker and coffee drinker so my teeth are pretty stained. I have been using this for a week and my teeth are so much whiter. I definitely recommend this product and I am deeply satisfied. Nothing else I've tried has worked this good.

[This review was collected as part of a promotion.] Works like a charm! I have used strips for years and have always been annoyed by the feeling of them. This solves that issue!!! I don’t have to sit with plastic on my teeth anymore to get the whitening!

[This review was collected as part of a promotion.] I would say it works.. but nothing too drastic or amazing on me. Very slow improvement. I would maybe give it more time and see but I have already given it around a month. I would say there are maybe better products in the market.

[This review was collected as part of a promotion.] I love this teeth whitening pen it works really well and fast! It doesn’t taste bad and it doesn’t feel gross. Definitely would buy again! Definitely recommend to anyone looking for a teeth whitening pen !

[This review was collected as part of a promotion.] First time using a whitening pen. I did notice some difference in the whitness of my teeth. Did not use everyday though mostly due to forgetting to apply it. I do have sensitive teeth and this did not irritate them at all. In the future I would probably choose whitening strips over the pen.

[This review was collected as part of a promotion.] I haven’t had one of these in a few years, but they essentially still work the same way (don’t drink water etc for at least 30 minutes after using the pen). Also, I feel you need to use it consistently, as I didn’t notice any results for what felt like a week. I do have 2 crowns but in my other teeth, it wasn’t as bright as I hoped after a few weeks, but everyone’s dentin is different (that’s the surface behind the enamel). Also, remember not to overuse, these can affect enamel after months of use :-)

[This review was collected as part of a promotion.] i’m so excited to receive this. It works perfectly for me and it’s very convenient to have on the go! is one of my favorite brands to brush my teeth with and I’m so happy to have a teeth whitening pen that actually works!
