The Colgate Professional Refill Pen helps make maintaining your white smile easy.

The precision whitening pen applies the quick drying gel only where you need it for best results.

The hydrogen peroxide in the gel turns into active oxygen to break down stains, whitening all areas of your teeth at the same time.

The Colgate Optic White gel has a short 10 minute wear time when used with the Colgate Professional LED device.

Includes one 6% hydrogen peroxide serum pen (2.5 mL).
