Colgate Optic White Express Pen | How To Use

Get your smile ready for that upcoming special occasion with fast teeth whitening! With the Colgate Optic White Express Teeth Whitening Pen at your fingertips, you’ll see whiter teeth in just 1 day* in a few simple steps.
1. DRY: After brushing teeth, dry teeth with a tissue. This helps the serum adhere to your teeth.
2. CLICK: Click until the serum appears. The first use may require up to 20 clicks.
3. APPLY: Apply a thin layer to each tooth and allow to dry. 1-2 drops of serum covers up to 4 teeth. Wait 1 hour, then brush with water to remove.
4. REPEAT: Repeat process for a total of 3 applications on Day 1 (suggested morning, noon, evening), and a total of 2 applications (suggested morning and evening) 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.
*Starts working after 1 day when used as directed. Individual results may vary.
