I suffer from my childhood to extremely heavy sweating and I - after I knew that this is not normal - tried thousands of deodorants; Already after 5 minutes I had sweat rings to go anywhere else, without moving. Even in winter, on the couch ... terrible and disturbing. When I then read by Yerka, I was once skeptical, especially since it yes even a bit of what it costs. Now I use it - so to speak, as a last resort before an operation - for almost a month and have to say: It saved my life !!!!!! For the first time, since I can remember, I have no welding rings up to the knees! I can even back wearing colored clothes, without any jacket, cover the shoulders !!!! Even my beloved blouse I can safely wear them again after years! Now I belong actually to the people who, despite freezing temperatures do not have to move 10 times in the winter! It's really too good to be true! : D
For "downside" Aluminum: good, Yerka contains some of it, but if you do not use every day (! I need it now only 2 times a week), which for me is absolutely fine!
