I try this tooth whitening powder it is MYR$15 130gram. It is not quite suitable for me, I find that my gum bleeding after using it. So I try to use it twice a week instead of everyday. It is blue bottle colour and I still prefer Darlie tooth paste.
It is not really refreshing, if you like Darlie it is big difference!
I forgot to say that I don't think I will buy this product again!
