Too much coffee? Tea? Smoking? Maybe you've never even tried to whiten before? If you have serious stains, and never thought whitening would work for you, this intensive 12-day whitening system will make you a believer! Our proprietary whitening serum PLUS power boosters - that's the "double action" - work against even the deepest, darkest stains. It's tough on stains but easy to do, gentle on teeth and gums yet visibly effective.

Each double-action ampoule contains two separate inner capsules, each 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, the new mixture goes to work in two ways. One liquid contains ingredients which release stain-removing oxygen ions, and the other accelerates the release of those ions, to speed up the whitening results. Once blended, the two individually encapsulated formulas work together to whiten better and faster than any single formula can.

With other systems, whitening teeth with older or darker stains can mean a lot more effort for you – more days, more hours of treatments. But with Double Action Whitening System, two complementary technologies work harder to whiten, so you don’t have to. Use the convenient ampoules anytime, anywhere, and before you know it, you’ll have the beautiful white smile you’ve always wanted!
