What is the difference between this purple serum and toothpaste?
Toothpaste is intended for use twice a day because it contains fluoride, which offers protection against cavities. Colgate Optic White Purple Serum is intended as a booster to whiten your teeth immediately after brushing*.
How does the Colgate Optic White Purple Serum work?
It contains a dual-action formula for instant color correction* and long-lasting¹ whitening results. It does this by using the color purple to neutralize yellow, giving you amazing whitening results! And with micro-polishing minerals, it also removes surface stains².
Does the Optic White Purple Serum replace my toothpaste?
No, our Optic White Purple Serum does not replace toothpaste, because it contains no fluoride and offers no protection against cavities.
When and how often should I use the purple serum?
Use our purple serum after brushing your teeth. You can use it every day or whenever you need an extra whitening boost. Apply one pump to your toothbrush and then brush for two minutes. Spit out the excess serum and rinse your mouth thoroughly after each use.
Is the purple serum safe and suitable for daily use?
Our Colgate Optic White Purple Serum is safe for enamel with daily use and should not cause irritation.
