I was invited, via influenster and crest, to review the whitening strips. I have just used it for the first time. I have noticed some significant changes.
1. The box is much nicer than it once was, I like the structure and the sturdiness, especially since I have to keep this box for many days and it typically sits next to a sink.
2. The gel formula on the strips have changed. The previous white strips I used, and was dissatisfied with had a watery gel that slipped on my teeth. This new gel formula is definitely improved and a thicker and sturdier.
More to come as I use them. So far, so good! :)
