I did a review last year on the iWhite O2 Professional teeth whitening kit.
You can watch it here if you haven't seen it.
It retails at €29.99 but I have a link HERE to a website that is currently selling it for just €20. Bargain or what!!.
I love this product, I have used it twice and was very happy with the results.
Check out the Before and After photos HERE
If you are a heavy coffee/tea drink, smoker or have just eaten too many sweets I would really recommend this product. It takes some getting use to (having to use the sexy mouth tray) but the results make it all worth while.
Hope you find this useful, feel free to link it to friends and family... I'm sure they won't find it insulting AT ALL!
Love,
Sarah
