Active Wow Teeth Whitening Charcoal Powder Cinnamon

Been using this a few times a week for the past couple of weeks. Haven't had anyone notice that my teeth are whiter but they definitely feel cleaner and seem whiter to me. Seems quite expensive but you do get a lot considering how little you need for each brushing.

I tried it twice a day for 10 days and it didn’t make any difference. A waste of money in my opinion...
