Double Action Whitening System is a terrific investment - it takes just minutes a day, and the dramatic results will make an impact every time you smile! It provides the most intense whitening available from GO SMiLE, yet it's gentle and comfortable to use. 

The 12-Day System is a great choice if you have darker teeth, drink a lot of coffee or have other staining habits, or if your teeth have never been whitened before. The extended length of the treatment - 12 days rather than the 6 days recommended for moderate staining - gives the system time to penetrate into teeth and remove even older, deeper discoloration. Advanced technology removes years of stains and the natural yellowing that happens with time, so your smile will look not just "better," but truly "beautiful." It's the fastest way to look 10 years younger! 

The secret is the patented, apply-and-go ampoule – there are no messy strips or uncomfortable trays. Each single-use ampoule holds two liquids in separate capsules. One capsule contains our proprietary Hyperox(TM) whitening technology, and the other contains power boosters, accelerators, and added sensitivity protection. The two liquids blend when the ampoule is activated to form a supercharged "double action" serum that whitens better than any single formula can!

Use one ampoule each morning and night. Simply squeeze it to pop the two inner capsules, and rub the powerful combined serum into your teeth with the built-in applicator. The serum adheres to your teeth and does the whitening work, while you go on with your day.

Your teeth will be dramatically whiter In just a few days, and you'll look brighter, fresher, and more youthful...people will notice! No other beauty product makes a faster, more significant difference in how you look and feel. Confidence is beautiful, so don't let less-than-perfect teeth hold you back. It's time to start loving your smile! 

The success of teeth whitening depends on many factors. The 6-Day system is sufficient to whiten most smiles. If you want even more dramatic results, or if you have older, deeper, or stubborn stains, we recommend you choose the 12-Day system.

Includes 24 0.027 oz Double Action Whitening Ampoules


Rub the contents of one ampoule into your teeth each morning and night, after brushing, using two ampoules per day until you achieve the level of whiteness you desire. Be ready to apply to teeth right away — serum may flow out quickly. Continue to squeeze and apply fluid until front of teeth are coated. Don’t eat, drink or rinse for 20 minutes to allow it to work.
