[This review was collected as part of a promotion.] So far this seems like a good product. The process is easy and straight forward. The instructions say you can do it multiple times a day which is surprising. I'm not in that big of a hurry. The light seems to be very durable too.

[This review was collected as part of a promotion.] I am a huge coffee drinker and smoker, need I say more? I also have yellowing teeth. Of course I go to the dentist regularly but I wanted to try this product to see if it would help whiten my teeth. So in the box, you get a tube of leave-on teeth whitening treatment, a wand applicator and an LED accelerator light. It is very simple to use, just squeeze the teeth whitening emulsion onto the wand applicator. Apply the product making sure to cover all surfaces of your teeth. Then you use the LED acelerator light against the teeth until it turns off automatically. It is so convenient to use and I have seen a difference in my teeth already although I have only used it a short amount of time. I would be careful if you have sensitive teeth because I don’t know if this product would affect you.

[This review was collected as part of a promotion.] I got my Crest WHT EMUL Light with the Crest whitening emulsions and I started using it that day. It is a very good product. It also has the light with it. I used it and got results the first time I used it. It whitened my teeth really good. I liked that it had the light with it. I have gotten good comments about how white my teeth are. It is very good at whitening teeth and you can use it more than once. I love how my teeth are so white now. And now I would use nothing but this product. I have no complaints about this product. This is a very high quality product and I would highly recommend it!

[This review was collected as part of a promotion.] Im so satisfied with using this! Yes, its uncomfortable at first but the results are astonoshing!! I can not believe how white my teeth are now! They went from being a Darkish yellow (thanks coffee) to actual white! I cant imagine how extended use of this would go - I would have pearly whites!!

[This review was collected as part of a promotion.] Love this stuff. The gel you put on your teeth is nice and thick so it actually stays on your teeth. I dry my teeth and mouth and then wear it for about 30 mins. I noticed a difference after the first use.

[This review was collected as part of a promotion.] I have used the crest emul light for two weeks and I love it, pros it’s easy to use and it shuts off to let you know it’s time to remove the light from your mouth. It doesn’t have a bad taste to it either. Cons there isn’t any instructions but it’s pretty simple to use. Also, the wand it comes with is really tiny so for each tooth I had to keep putting a little more product but other than that I absolutely love this!

[This review was collected as part of a promotion.] I have used the Crest White Emulsions kit 4 times so far. I have seen a difference which I like. I don't like how you have to keep the solution on for 30 minutes before you use the light. Otherwise it is a good product to keep you teeth white in-between cleanings.

[This review was collected as part of a promotion.] I was initially skeptical about using a home emulsion whitening kit. I didn't think it would be as effective as the whitening at dentist office. I was pleasantly surprised. I have very sensitive teeth and worried about how my teeth would react. I used the emulsion per the instructions and used the LED booster light after application. To my surprise I could see visible whitening after the first treatment with no sensitivity issues. I like how easy the emulsion is to apply and the whole process is very quick - about 5-7 minutes total. It's a great alternative to having to go to a dentist especially in these pandemic days.

[This review was collected as part of a promotion.] I got this a few weeks ago. I was nervous to try it but it was very easy to use. I can pop it in and do other things while the time passes. I have seen a slight change in the color of my teeth. It doesn't hurt or cause any sensitivity. I will definitely keep using it to see how white it gets my teeth.

[This review was collected as part of a promotion.] I have been using this every week for the past few weeks and have noticed a visible difference in the whiteness of my teeth! It’s easy to do while working from home or doing other errands around the house. I will definitely continue using this product in the future!
