How do I use the Colgate Optic White Overnight Teeth Whitening Pen?

CLICK: Click the pen until a small drop of serum appears on the brush tip. First use might take up to 20 clicks to get that first drop to appear.

APPLY: Dry your clean teeth with a tissue. Apply a single thin layer of serum to each tooth and wait 10-15 seconds for clear film to form. Avoid contact with gums and lips, as it may cause a tingling or cooling sensation.

WIPE: After use, wipe the brush head with a dry tissue to remove excess liquid. Do not clean the brush head with water. Close the cap tightly until you hear a click to prevent drying out.

SLEEP: The dried coating stays on your teeth to whiten overnight.

BRUSH: The next morning, brush like normal to remove the coating and reveal your brighter, whiter smile.

REPEAT: Two weeks of treatment is recommended for the best results.
