Terahertz Gua Sha Round Spoon Type 111.8mm × 34.8mm, Round bead 12mm 34.5g 1 piece Only beautiful people know: Next-generation beauty that repairs cells [Recognized by NASA] In 1981, NASA announced that "Terahertz waves are a frequency that has beneficial effects on the human body, essential for the metabolism, growth, and development of life." [Terahertz] Terahertz ore is an artificially created mineral made by melting quartz at high temperatures and collecting silicon. The 1 trillion vibrations per second (Terahertz waves) emitted by Terahertz ore penetrate various substances such as wood and plastic, activating cell genes. Also, because of its high thermal conductivity, when applied to ice, the vibration plus heat conduction from the hand will quickly melt the ice. It is said to have effects such as promoting blood flow, repairing cells, and enhancing natural healing ability, and is widely used in medical and industrial fields. Not only is it attracting attention for its positive effects on beauty and health, such as cell activation, improved blood flow, and skin firmness, but it is also popular as a "scientifically effective power stone."
