I read all the reviews on the product and although they were mixed, the pinnacle of users opined that this product was helpful and minimized staining. I used the entire product for a month and quite candidly, did not notice any significant difference worth discussing. There are other better products that work significantly better. Definately pass on this one . .
Simple and Quick
I have only been using the whitening system for about a week, but I can already tell a difference in the shade of my teeth. Its simple to use and very quick. You already brush your teeth, might as well whiten, without all the hassle at the same time.
Whitens without pain
This definitely whitens better than my regular "whitening" toothpaste and is on par with whitestrips. Unlike whitestrips, this seems to be a bit more gradual and for that reason is pain free. I only had a little bit of cold sensitivity and normally my teeth hurt a lot with whitening treatments.
Nice product, works
This system works great.. .when I remember to use it! I wish it was in a single tube, but it works well. I noticed a difference in just a few uses. Nicely done Birchbox.
i have used this product off and on for a couple of years very good product use it two ,or three times a week
