Enhance your whitening routine overnight with the patented Colgate Max White Overnight Whitening Pen, which whitens teeth by up to 3 shades*! It's easy to incorporate into your evening beauty routine – brush your teeth as usual, then apply the serum to dry teeth and let it work overnight.

Max White Overnight Whitening Serum is enamel-safe, dries quickly on the tooth surfaces, and starts working from the first use. For the most dramatic results, use the Max White Overnight Whitening Pen in combination with the powerful Colgate Max White Ultimate Whitening Toothpaste and the Colgate Max White Ultimate LED Whitening Device, which enhances the whitening serum's effectiveness in just 10 minutes of use.
