COLGATE OPTIC WHITE OVERNIGHT WHITENING PEN REVIEW
Well, judging by the side by side photo it looks like my teeth were whiter before. Dang!!
I’ll keep using it until it runs out. Maybe I need to do another week.
I’d say don’t waste your money, but maybe my teeth just didn’t react to the serum like it’s supposed to.
I don’t know. Lol!!
Anyway, I hope this gave you an idea about how this works.
Thanks for watching!!!
