overstimulated my thyroid gland.
I got this item in a small and possibly unwarranted fit of panic over a bit of loose skin under my chin (I'm 39 but regularly get mistaken for 25, so this was not a welcome sight). I decided to follow the instructions for "international customers" for the neck area on the DVD (NuFace is not FDA approved for the neck or body) and used it for about 3 weeks. It did uplift the area I was worried about, and improved the look of my skin, but I also found that it overstimulated my thyroid gland. I could feel some discomfort swallowing after use of the device and I developed symptoms related to overstimulation of the thyroid. I had to stop use of the NuFace and I did feel better so it was luckily only a temporary situation. Of course, after about a week of dis-use, the skin pretty much went back to the way it was before. I would only recommend at the most that this be used under the chin/jawline but not further down the neck as the DVD shows. Personally for me, I dont think this is a product that I can comfortably use long term due to the worrisome side effects. I'm going to look into creams and facial yoga or something else that may take longer to work, but will be better for me in the long run.
