The product is as advertised. I have been following instructions for application of the powder. However, after around one week of brushing for two minutes a day I felt that it may be more effective through doubling the time to four minutes. My teeth appear to be a little more shiny, but a tea stain across my lower front ones is proving stubborn for removal. Having said that, there are signs that it is fading now a little. My dentist tells me that my teeth have yellowed naturally through age, and this is something which I hope that the product will address over time.

Absolutely love it

I was very impressed with this powder didn’t think it would work but it’s whitened my teeth I’m still using it and will carry on using it

Only been using the whitening powderfor a couple of weeks but so far so good 👍

Only half way through the jar, seeing a very slight whitening, will keep going.
