SNOW Extra-Strength Sensitive Teeth Whitening Serum - Oral Care Gel for Stain Removal & Whiter Teeth - Whitening Pen for Sensitive Teeth with Hydrogen Peroxide & Mentha Piperita

I love my SNOW. It gets my teeth looking white as white can be. Have used it for my own wedding and my best friends and the results do not disappoint!

Works like it says great value for the price. As good as going to the dentist for whitening

I've used many other whitening products but they made my teeth ache terribly. With Snow I've had very minimal sensitivity, even after using it multiple times.

Just used this product for the first time last night. I used it for 30 minutes with a blue LED light. I didn't experience any pain, but it did make my tongue really tingly and numb feeling when the spit started collecting in my mouth. LoL Seems to be a little whiter I guess, but I'm sure it probably takes a few uses to make a noticeable difference. Overall though, I certainly haven't found any reason to give it a bad review.

The product was larger than I expected which was a pleasant surprise

I’m not sure how this is labeled “sensitive.” A little bit got onto my gum line & made my gums bleed. 😳 I saw blood the second the product made contact with my lower gums. I’m going to try to continue using it. It did burn & sting when it touched my gum line.

My whitening solution was not air tight like I usually receive it from the SNOW official website. I received the product leaking which implies to me that it was opened/used before it was sent to me.

I'm not sure why some of the reviews are saying this isn't real SNOW product but this is my first time so I don't have anything to compare it with other than judging this product for what it is. I have tried quite a few teeth whitening brands lately and Snow is one of the pricier brands in the market.I got the one for sensitive teeth and I haven't tried the Max Strength one so I can't say if there is a difference in sensitivity but this one does not have that feeling after use. My teeth feels fine and doesn't feel any different other than the color. I'm on day 3 of use and notice my teeth is a few shades whiter. I think it works as well as some of the other brands I've tried and many other brands are now sensitivity free as well, so this isn't like a new technology. I wish they stated how many percent hydrogen peroxide is in this as some of the other brands have been more transparent with that information. I recently learned that whitening gels like this works best with a blue LED light. I don't have the mouthpiece from Snow but I have another one by Cheeky (they're great too) so I went ahead and used that one alongside Snow's whitening gel. So far I am happy with the results so I have to thank both products for helping me achieve results.I don't know why they named this "refill" because I was almost under the impression you needed to have one of their whitening pens prior to this but no, what arrived is a brand new pen with bristle brush. There is essentially no "refilling" of anything so if you are a first time user of this product, that's not an issue at all. In a way I do wish these pens could be refilled to prevent all this waste from going to landfills. I appreciate the clear, see through "window" in the pen because I can see how much gel is left and and order more if I see it running low.There are numerous teeth whitening products in the market and I've noticed that many of them are now made in China. That is one of the first thing I checked when I got this and it says Made in USA. It isn't that made in USA is superior but I know for some people the country of origin matters to them. I also made sure to check the expiration date and it is about 2 and 1/2 years out so this seems to be a relatively fresh batch. Overall I am happy with this product and it works. If you don't have the LED mouthpiece I would suggest getting one to speed up the whitening process.
