[This review was collected as part of a promotion.] I did use this whitening emulsion kit a few times a week, and saw little to no change. The directions have you apply a serum to your teeth, and then wait 30 minutes before using the LED light for 3 minutes or so until it shuts off. It recommends it up to 4 times a day I believe. But after using, you cannot eat or drink for an hour. Personally I didn't have time to use it multiple times a day and settled for once a day before bed. I didn't see much of a change at all, and I already don't drink coffee or soda. Unfortunately, there was not enough of a change to warrant purchasing again for me. I do use crest's other products, and enjoy them though

[This review was collected as part of a promotion.] As a heavy coffee drinker, I love the easiness of using this product! the applicator works extremely well to hit all those hard to reach areas of the teeth and the whitening light makes all the difference! The taste isn't bad so that's a fringe benefit! It definitely works, even after one application!

[This review was collected as part of a promotion.] There is nothing as sexy as confidence. Historically, my teeth have been a chink in my armor; I feel put together with the exception of my teeth. I have tried numerous teeth whitening methods with little to no results. I had my doubts about this product so I documented my results for a side by side comparison to know conclusively whether it made an impact. I am happy to report that it did, by my estimation. The kit is easy to use. The instructions are straightforward and comprehensive. The gel is slightly unwieldy, but anything worth having is worth working for, right? I tend to need to refill the applicator to get all of my teeth, but that's not a big deal. The thirty minute wait prior to light activation is not the greatest experience, but it beats out sitting at the dentist's office for a full hour with the light in my mouth and it's more affordable. I also prefer this to whitening strips as the latter feel awkward, make it difficult to speak, and can slip off. You can feel the gel but it's not uncomfortable. The worst of it is the increased salivation (which I'm not convinced isn't psychosomatic). Once the process is complete, the applicator wand is easy to clean and the kit includes a stand for the gel and applicator for hygienic storage between uses. I love that I can now keep my teeth clean without having to give up things I love and without creating a tooth sensitivity issue pursuant to that goal. Like any new experience, this takes some acclimation, but it is easily inculcated into the daily routine and well worth the results. I am so pleased with this product and am now pleased with my smile.

[This review was collected as part of a promotion.] I am completely obsessed with this teeth whitener! I got it a little over a month ago and I am already seeing some major improvements!!! Everything was very easy to apply and the light is such a cool feature to at home teeth whitening! One of my favorite parts is that it doesn’t leave my teeth super sensitive! I would totally get again!!

[This review was collected as part of a promotion.] I brought the Crest White Emul Light about a month ago and absolutely love it. I’ve also noticed a big different in my smile. Crest has always been a reliable brand though my tooth care odyssey....I’m glad they continue to be consistent.

[This review was collected as part of a promotion.] For the short period of time I have been using this product I am seeing a difference in the shade of my teeth. I like that it's easy to use and doesn't irritate my gums. I'm impressed that it has shown change in the color of my teeth after just a few uses. The packaging is very nice and inviting. I just wish it came with an extra brush but the one that it comes with is easy to clean and store.

[This review was collected as part of a promotion.] I got to try the crest whitening emulsions kit with led accelerator light and overall really happy with the results. Its easy to use, you apply the whitening cream from a squeeze tube onto a flexible rubber textured spatula and apply it to clean dry teeth. 30mins after application you apply the led light. it is lightweight and about the size of a hockey puck, you put the rubber mouth piece in your mouth and click the button on the side to turn it on. It is comfortable to use. Not only did i see fast results from this product in whitening my teeth, it does as advertised for little to no sensitivity. Finally a product that doesn't cause any adverse issues when I'm whitening my teeth. Love it!

[This review was collected as part of a promotion.] The Crest White Emulsions Light works okay. I am not a big fan of the texture or taste of the gel you have to put on your teeth though. It's easy to use though which is nice for a teeth whitening product.

[This review was collected as part of a promotion.] I've only used the Crest Whitening Emulsions a handful of times, but I'm already very pleased with the results! The applicator takes a bit to get used to, but once you do, it is very easy to use. The gel itself goes on easily and once it is on, it only takes a few minutes to feel like it isn't even there. It has a slight minty taste, so if it does get on the tongue, it is not unpleasant. After the three minutes with the LED light, the emulsion is totally gone and my teeth felt clean and smooth, and looked incredible. I am excited to continue using it!

[This review was collected as part of a promotion.] I have been using the Crest whitening system for about three weeks now. My teeth are looking much whiter, but not as much as I thought. This product is much more natural looking and the brighter then a previous model I've tried. I would recommend that you don’t eat/drink for an hour vs. 30 min, because I still feel the emulsion on my teeth 30 min later. I think that’s why it works so well. I have been using this 2x per day and am very happy with the results!
