This product has no side effects. First of all, it should be understood that the product is made of graphene, which generates photon energy field after being electrified and acts on subcutaneous fat. Infrared rays and negative ion waves can help the human body resist bacteria, deodorize and remove mites, accelerate the vibration of abdominal fat, and make the body full of magnetic fields. Although photon energy band is used in abdomen, it can radiate all organs and tissues, even bones and nerves can benefit. After a period of use, the metabolism of cells and tissues is obviously accelerated, making people feel as light as a swallow. With a new skin coating, there is no foreign body sensation when using it. You only need to use it twice every morning and evening to improve your health and dilate your blood vessels. At the same time, skin and mucous membrane can also bring more gentle effects and promote the formation of fibroblasts. This product is made of natural materials and high-tech patents, and has been completed through dozens of processes. Using Vio 8848 photon band. Not at all, because light energy field is a kind of physical energy field, which has no side effects on human body.
