This is a beauty device that uses terahertz waves. Please refer to the photos for the size. 150 yen discount for multiple purchases! Please comment before purchasing. Terahertz ore emits terahertz waves, which are electromagnetic waves that have properties between radio waves (transmitting) and light (traveling in a straight line). These terahertz waves are classified as "growth rays" and are said to reach deep into the body, restoring cells to a normal state and activating them. In the human body, terahertz waves have been proven to greatly contribute to health promotion by improving stagnant blood flow and raising basal body temperature. It is said to improve not only coldness and stiffness, which are typical problems caused by poor blood circulation, but also to bring about a good night's sleep because it also has the effect of regulating the rhythm of cells. In addition, the increase in basal body temperature also increases metabolism, and effects can be expected in dieting and beauty. It has the power to address a wide range of body concerns related to health and beauty, so it is a stone that I would recommend regardless of age or gender for those who want to be youthful and healthy.
