[This review was collected as part of a promotion.] Easy to use gel pen that paints on teeth effortlessly and doesn’t taste bad like some gels! The light fits comfortably in your mouth and was perfect to just sit back and relax while it does the work. Packaging was simple and to the point.

[This review was collected as part of a promotion.] I like this product! Its very easy to apply by twisting the applicator brush until the gel comes thru. You just brush on each tooth and doesnt have a terrible taste. The blue light is quick and easy to use

[This review was collected as part of a promotion.] The pen uses a small brush tip for precise gel application, which you leave on teeth for 30 minutes before “boosting” effects with the included LED light device. The device goes into the mouth and is easy to hold (and not heavy), and turns itself off automatically after the recommended treatment time. The gel is meant to brighten and reduce stains, and it did a decent job of lifting my coffee stains and lightening my teeth about one level. If used regularly, I suspect it would help maintain tooth brightness, but I don’t think it’s really going to affect long-term staining or changes in color like an office visit can. The process is easy and clean, though.

[This review was collected as part of a promotion.] I have found a great whitening treatment that works really well. I drink a lot of coffee and black tea, which has made my teeth very dark and brown. This treatment set is not only effective but also easy to use. I can take it with me and use it anywhere, without the hassle of carrying too much stuff. Plus, the price is quite reasonable. I highly recommend it!

[This review was collected as part of a promotion.] I recently tried a whitening gel package that comes in a convenient pen form with a brush tip, making it incredibly easy to apply directly onto the surfaces of my teeth enamel. The package also includes a UV light device, which enhances the whitening process. To use it, I simply apply the gel, switch on the light, and then relax for 30 minutes. After just a week of daily use, I've already noticed a significant difference—my teeth are visibly a shade lighter! While I did experience a bit of sensitivity, which is common with teeth whitening products, I find it perfectly manageable. I highly recommend this product to anyone looking to achieve a brighter smile from the comfort of their home at an affordable price!

[This review was collected as part of a promotion.] This product was pretty easy to use and I saw the effects right away. Specifically on my lower teeth I saw improvement in just one use! The flavor is actually enjoyable to my. I like that the light has an automatic timer. The hardest part was holding my mouth open for 1 minute for the gel to dry! 😂
