I know what you are thinking, how can a toothpaste change your life? But after a week my teeth were noticeably whiter and i had so many compliments on them, someone even asked if i had them professionally whitened. So yes it works.
On the packaging it says 'one shade lighter in a week' and it definitely delivers that. I have only used it for a week and i cant wait to see the results after another week.
It tastes the same as other Colgate toothpastes i have used and is not too strong, as i know a lot of toothpastes i have used previously used have quite a strong minty taste.
I have never used teeth whitening products previously and was going to buy Coco White after one of my friends and so many celebrities have said how amazing it is, but when i saw Optic White advertised on the TV i thought i would save some money and try this. And i am so glad i do.
