@rennielelee: 🦷 Colgate Optic White Purple Serum 🦷 Whitening boost, instant color correction for yellow tones! This is Colgate’s first ever Purple Serum, inspired by the color theory! Also removes surface stains and is enamel safe! To use, apply 1 pump on a toothbrush and brush gently for 2 mins! Expel excess and rinse! My review: What an interesting product! It’s a teeth whitening serum that you use similar to a toothpaste (brushing in gently), but it’s not a replacement. Really easy to use. I must say I find it quite effective! I do see some improvements on my teeth color after using this. I’m using this together with the purple toothpaste of the same range! Give it a try! @tryandreview @Colgate Palmolive #colgate #purpleserum #teethwhitening
