Uncap the ampoule to expose the applicator tip. Hold the ampoule with the applicator tip facing down. Squeeze dots marked 1 and 2 in that order to pop the two inner capsules and blend the formulas. Continue to squeeze the ampoule gently until the applicator tip is fully saturated before you apply the serum to teeth. Whiten by applying the newly-blended formulas evenly onto teeth. Do not drink, eat or rinse for at least 20 minutes.
