1. Click
Uncap and click until serum appears. 1-2 clicks is enough for up to 4 teeth. It may take up to 20 clicks for serum to appear on the first use.
2. Apply
After brushing your teeth with water, dry top row of your teeth with a tissue, then apply a thin layer of serum to each tooth, wait for 15 seconds for the clear coating to form, and then repeat on the bottom row.
3. Whiten
Leave the film on your teeth for 1 hour. Avoid brushing your teeth or eating (you can drink water). After 1 hour, remove the dried film by brushing your teeth with water.
4. Repeat
Repeat for a total of 3 applications on Day 1, and a total of 2 applications on Days 2-7
5.Clean
After use, wipe the brush bristles with a dry tissue; do not use water. Close the cap tightly until you hear a "click" to avoid hardening of the tip. If it hardens, do not rinse with water. Instead, click pen 2-3 times and the new serum will soften the bristles.
