iWhite Express is a revolutionary, dental safe teeth whitening device with immediate results. The ultra-thin sponge structure has a great absorption capacity. On average 88% stains are removed within 1 minute.**The stain eraser sponge has to be activated with a few drops of the iWhite Express teeth whitening serum which contains natural whitening enzymes, enamel strengthening actives and cooling agents for a fresh-breath sensation. The combination of the stain eraser sponge and whitening serum leads to pearly white teeth and long term cleanliness of the tooth surface.
** Stain removal percentage based on the change of the biometrical delta E value (In vitro evaluation of iWhite Express for stain removal and whitening effect versus a positive control).
