Crest 3D White Professional Effects

I started using the crest range after a friend brought some back for herself from the states. After a week or so of sing the advanced vivid range her teeth where visually lighter, I decided to try the professional effects as I am a heavy smoker, after 4 days my teeth looked so much better!

The advanced seal helps keep the strips attached so I usually just spend the 30 minute treatment time on the phone :) Getting them in the UK can be difficult I have noticed a lot of fakes on Ebay, I use 3dwhitestrips, Hope this helps!
