Actually yes, I’ve been using it for some time. I saw some bloggers using a powder from VIRGINIC and I really wanted to try it out. I was surprised to see that it really works. My teeth are whiter than they used to be, but I don’t use the powder very often. I simply don’t know if I should used it on a daily basis. The only thing I don’t like about it is its form. There is a lot of fallout and a lot of cleaning afterwards. Next time I will buy a Virginic toothpaste with this powder instead.
