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, returning 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 common problems caused by poor circulation, such as coldness and stiffness, and also to promote restful sleep due to its ability to regulate the rhythm of cells. In addition, the increase in basal body temperature also increases metabolism, which can be expected to have effects on 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.
