Formulated with a patented active oxygen-based tooth whitening technology, it whitens teeth in 3 days. As soon as you brush, Colgate visible white O2 gives off a warming effect inside your mouth. Along with this, it releases a gentle wave of ultra-fine whitening foam - that’s the active oxygen.

The millions of active oxygen bubbles get absorbed gently into your enamel and whiten teeth from the inside out! Available in 2 refreshing flavours: aromatic mint: like a rushing mountain stream, the freshness of this herby wintergreen mint gives a refreshing flavour that lasts. Peppermint sparkle: fresh, bright with a slight hint of spice, this delightfully balanced flavour brings a long-lasting flavour that feels like your mouth is sparkling.
