“I did use them just once and it worked. I could really see some difference in just one application. The reason why I did not go to the full 2 weeks treatment, is because I have fake teeth in the front and the strips do not really whiten them. So I decided not to go further in order to not create a big contrast between fake and naturale teeth. I am really sad about that because I am sure I could have great results... that’s the only reason why I leave 4 stars instead of 5. (It wasn’t mentioned in the description)”
