As an orthopedic surgeon, I recommend the use of Sugoola Far Infrared Titanium Ion Heightening Knee Guard for augmentation, which utilizes far infrared energy to act on titanium to promote the formation of titanium ions. These titanium ions react with calcium ions in the body, leading to the formation of wider, more porous bone trabeculae. This process stimulates the creation of new bone marrow and bone structure. The technology also releases trace ions that enhance blood circulation, stimulate acupuncture points, relieve muscle contractions, and reduce inflammation. Thus, this nanoscale coating is an innovative solution to enhance physiological processes in the body, which is why I recommend it. What makes Sugoola Far Infrared Titanium Ion Heightening Knee Guard the perfect solution for height enhancement? The Sugoola Far Infrared Titanium Ion Heightening Knee Guard can be safely washed in the washer and dryer, as well as in cold and hot water, without compromising functionality. We recommend washing once a day. The nano-film is coated with a cross-linking agent, which chemically reacts with the micron-sized titanium fibers and the nano-sized tourmaline coating at the molecular level to form strong chemical bonds. This enhances the adhesion between the Schoger coating, titanium fibers and the substrate. Frequent washing and drying will not affect its functionality.
