The Teeth Whitening Serum uses a safe amount of phytic acid extract from rice bran and sodium phytate to naturally whiten teeth without damaging the tooth enamel. These non-bleaching ingredients work synergistically to absorb and dissolve tooth surface pigments, removing years worth of stains from the different things you consume and bringing back your dazzling smile in as fast as 7 days!

And I saw results within a few days. I finally found a teeth whitener that contains no sulfate and peroxide, which are extremely sensitizing to my gums and teeth. Love it! Layla Cox, AUS If youre like me with yellow stains and discoloration since my teeth grew in (thanks, genetics), I recommend the Teeth Whitening Serum. I have been using it for a week straight and already notice a difference. It cancels out yellow tones so they appear brighter. The ingredients are also safe for sensitive teeth. I cant use whitening strips because my enamel sucks. This is a good one. Highly recommend! Brent Davis, USA Im a smoker and regular coffee drinker, and it shows on my teeth.
