Double Action Whitening Ampoules provide enamel-penetrating whitening power in just minutes. They are clinically proven to provide a better experience, and a deeper, more effective level of whitening than strips or trays. They are fast and easy to apply, and fast to work, making your teeth visibly whiter every day you use them. Double Action makes it possible for everyone – no matter how stained their teeth – to achieve a whiter, more beautiful, youthful-looking smile.

The secret is the two formulas in each patented ampoule – one activates and "supercharges" the other to whiten better and faster than any single formula can. The combined liquid penetrates quickly and deeply into teeth to remove stains fast - many people see results after just 1 day!

The treatment is simple and easily personalized to deliver whatever degree of whitening your teeth need. Use 1 ampoule each morning and night for as many days as it takes to achieve the results you want. The 24-ampoule kit is a 12-day supply - enough to whiten even darker or deeper stains.

Activate the ampoule, rub the serum into teeth with the applicator, then go on with your day. It’s the easiest way to get white teeth, and the formula is proven to be gentle on gums, and safe on all dental work.

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.
