The six-day Double Action Whitening System combines two powerful, patent-pending GO SMiLE® formulas to penetrate teeth and effectively lift stains, even beneath the surface. It works quickly and effectively to make a visible difference in your smile and with virtually no sensitivity or irritation to teeth and gums.
How to use: Each ampoule contains two separate inner capsules holding a different liquid formula. Right before you’re ready to use it, squeeze the ampoule to break each of the capsules to combine the liquids. As you apply the mixture to your teeth with the built-in applicator, one liquid releases stain-removing oxygen ions and the other accelerates the process and your whitening results. Once blended, the two work together to whiten better and faster than any single formula can.
