I was pretty suspicious about the curcuma. At the end of the day, no smell. I think it depends on the people, our perspiration and our diet, but for me it is very fast. I know that for others it takes a little time to adapt, in my case it was done quickly. I used it at home first when I did not go out to be sure to have no problem, but I quickly used it even to go outside with hot weather.
I really recommend this product. Leave out your chemical deodorants that are not so effective and remain dangerous for your health ... This natural product works wonders!
