Recently i got to try the 3D white Whitestrips Whitening power 4.
I'm an Influenster member so i got the opportunity to try these absolutely for free.
The Crest box came with 20 whitening treatments. I have tried the white strips personally and i think it does work you can automatically notice the difference the first time you try these whitestrips, your teeth instantly look a little bit more whiter and whiter. The only thing i would say hat i don't enjoy from these strips is the feeling once you've left it on for more than a minute or 2.
Influenster is a site in which you unlock badges and according to those badges is how they pick you for a certain voxbox's they will be giving out. All you have to do is a survey to unlock that badge and some other stuff.
I give these Crest Whitestrips a five out of five stars
