“My experience with the Biotrohn was because one day my wife was paralyzed half of her face. The doctors told her that it was due to a virus and that it would take months for her to regain facial mobility and they were not sure of the evolution. I quickly remembered the device and she started using it. From the first minutes she told me that she felt the microcurrents in the area of the paralyzed face. Well, it was an absolute joy that in just three days she managed to fully recover! ”
