Colgate Optic White Overnight Whitening Pen (2.35ml) provides easy, effortless and effective teeth whitening while you sleep.

Formulated to remove years of stains in just 1 week, this enamel-safe, teeth whitening pen includes a precision brush which dispenses a hydrogen peroxide-based whitening gel directly onto the surface of each tooth with just the click of a pen. Each pen provides 35 nightly applications and has been designed to cause no tooth sensitivity during and after the whitening process. Works best when used nightly after your regular oral care routine. Cruelty-free & vegan-friendly.

Directions of use:

• Click the pen until a small drop of serum appears on the brush tip.
• Gently dry your clean teeth with a tissue. Apply a 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 the brush head with a dry tissue to remove any excess liquid. Do not clean the brush head with water. Close the cap tightly until you hear a click to prevent drying out.
