 Are cheek oils scientifically proven? So yes, they are absolutely scientifically proven. We've done a qualitative assessment of 200 people. 50 of them have used cheek oils. 50 of them use only the frequencies without cheek oils and a hundred of them never used any of our cheek oils or frequencies. People who used our frequencies have 15 to like 30% improvement for anxiety, sleep and mood and depression and pain. For people who use cheek oils, their ratings improved even more. So which means that both of our technologies are working well, the sound therapy and the g-co-magnetic therapy.
