Instructions: Use whitening pen nightly to remove 15 years of stains in 1 week – treatment should be applied after brushing just before bed. Apply a thin and even layer of gel onto clean, dry teeth by clicking the pen until gel appears (May take a few clicks on first use). The formula takes only seconds to dry. Sleep, and let the gel work its magic while you catch those ZZZs. The next morning, brush your teeth to remove the formula. Repeat nightly for a visibly whiter smile in 1 week. Each pen contains 35 nightly treatments.
