Smyle4you is one of the best whitening kit I have known since long time. My sister loves it and it looks like one of the best product out there.
The chemical content of smyle4you kit is equivalent to that used by surgeon during teeth whitening surgery. This product could be stored up to two years and so you can use it for a pretty long time and get a teeth whitening solution all at the comfort of your home.
The best part is, you try to drink tea/coffee and smoking lesser just because your teeth looks so white that you would be hesitant to get it yellowish again, lol
I would recommend you to try it yourself : Click here
