I have used this product for a while now and just bought another bottle. It’s a good product for taking dark yellow colors off your teeth like coffee/tea/Smoking stains. It’s a good product to use if you are looking for something to make your teeth more shiny and closer to white.

I waited 2 weeks to write a proper review. First, I understand why so many ppl are upset & giving negative reviews. The advertisements are not accurate. This product did not whiten my teeth on the first try. It took 2 weeks before I actually saw a difference.
