The efficacy of the iWhite Express is based on two elements; the stain eraser sponge and the teeth whitening serum. 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:
Erases stains in hard-to-reach surface areas
Removes stubborn teeth stains and plaque. On average 88% stains are removed within 1 minute/60 seconds*
Powerful teeth whitening serum: activates, whitens, strengthens & freshens
* 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).
