The 2023 New Version Ionic Shaping Sleeveless Shirt generates energy without the need for other energy sources (e.g. electricity). 2023 New Version Ionic Shaping Sleeveless Shirt provide the user with multidimensional massage and stimulation based on ion therapy, far infrared therapy and moxa therapy. They help to effectively stimulate blood and lymph circulation, relieve lymphedema and inflammation, and reduce fluid retention and cellulite. The EXPECTSKY Ionic Shape Vest features innovative technology with embedded graphene fibers. These fibers promote cell regeneration and improve nerve function, resulting in improved back health and posture. In addition, the vest contains millions of magnetic nanoparticles that create a static magnetic field that further promotes blood circulation and muscle relaxation. The effectiveness of the static magnetic field is further enhanced by the use of wormwood. By combining these two technologies, the EXPECTSKY Ionic Shape Vest has the combined effect of improving back health and posture.
