Review on Colgate Optic White Overnight Teeth Whitening Pen: 🦷 Powerful Stain Remover for Whiter Teeth - 35 Treatments Included! by Jessica Wright

**I used this Colgate Optic White Pen in combination with their Optic White Toothpaste** Although I used their Optic White Toothpaste consistently 2 weeks before, I can't say I saw a huge measurable difference in photos until I used this night bleach. I've used a variety of whiteners over the years, including tooth whiteners and various home use gels, some with very high concentrations of peroxide that were painful to use. I'm very torn between 4 and 5 stars. The difference in lightening is only a shade, maybe 2 lighter. So be aware that this pen is unlikely to turn heavily tea-stained teeth into blindingly white Hollywood teeth. The results will be modest. Good Points: - Doesn't taste horrible - It seems to stay on your teeth overnight and works like "magic" - Easy to use instructions (they made it so easy) Just apply after brushing your teeth overnight - Includes a handy one Holders that you can keep on the sink as a reminder. I'm giving this 5 stars for honesty. While the results are a bit modest, Colgate hasn't cheated at all with their marketing, truthfully reporting that their product didn't increase brightness by more than a few shades.
