Review on Crest 3D Whitestrips Glamorous White Teeth Whitening 🦷 Kit - 16 Treatments + 2 Bonus Express Treatments by Bruce Saywon

I doubted for a long time, but still I ordered these strips via the Internet, since they are not on free sale in Russia. Before that, I used more gentle strips as a test, they should be kept for only 5 minutes. I did not like them very much, as they quickly detached from the teeth. These strips should be kept for 30 minutes. They are very well glued, then it is even difficult to tear them off. Can be used as a course, and as needed. For example, I whitened my teeth to the desired shade, and then maintained the result once a week. It is advisable to refrain from drinking wine, tea, coffee, etc. coloring products. The effect is noticeable from the second application. Even people around noticed the color change! The only negative: with constant use, my enamel becomes very sensitive to cold. Then I stop the application and the sensitivity gradually fades away.
