I bought this product there 3 weeks, according to them, in the first use must see results, not at home, so disappointed ... I increases the power of the day, it m ' took about 2 weeks to see results, but yet they were not hugely obvious. I think that within three weeks / one month I will have the results I expect. Noted: I do not smoke, I have a balanced diet and brush my teeth 2 times a day. 90 good for one will not complain as it's quite a good price / quality anyway!
