Emily Stone Terahertz Gua Sha Plate Set of 2 Used a few times. There are no noticeable scratches or stains. [This one tool for both face and body!] Lack of firmness and signs of aging are caused by poor circulation and the accumulation of waste products. You can easily massage and care for your skin by using the Terahertz Gua Sha to promote blood circulation and imagine the flow, reducing puffiness and sagging. You can use it on the lymphatic areas around the face and on the whole body, allowing for an "itai-kimochi-ii" (hurts-so-good) ideal care experience. [Adopting Terahertz ore!] The synergistic effect of Terahertz waves, which emit a longer wavelength than infrared rays, and Gua Sha massage, allows you to easily perform massage to promote flow and lift the skin. This product is made of 99% pure high-quality Terahertz ore. [Achieving the best shape for easy handling] It's palm-sized and not too heavy, so you can use it in a relaxed manner. If it gets wet, just wipe it off with a towel. It is resistant to scratches and stains, and requires no maintenance.
