Courtesy of influenster I received the Colgate optic white pen to review and try out. I had tried crest white strips in the past, and while I was pleased with the results I hated that I would have to hide away for 20 minutes while I had them on. The idea of this "brush whiten go" slogan had me interested.
My first application went on very thick and almost chunky. I certainly wouldn't let anyone see my teeth like this. I also felt as though this paste was being swept off my teeth each time I closed my mouth. I didn't get much of a taste, which was good but I was still skeptical.
I used my optic white pen for two weeks and I am happy to report a brighter smile. I don't think it is as effective as the crest strips were for me, but it also didn't cause extreme sensitivity. Overall I was happy with this product and would recommend it to those looking for a in-the-go way to whiten your smile. Thank you Colgate and influenster for introducing me to this great product!
