Guang doctor semiconductor rhinitis therapeutic instrument

As far as I know, this product is irradiated by 650NM laser. This laser technology is widely used in medicine, and the laser in this band has anti-inflammatory effect in medicine. I specially read some professional medical articles, such as Application Research of Semiconductor Laser in Medical Treatment, Medical Application of Semiconductor Laser and Clinical Study of Treating Rhinitis with Low-intensity Laser Nasal Acupoint Irradiation on China Knowledge Network. Many medical articles agree with this treatment method, and I have also inquired about this quasi-brand name, which is a second-class medical device. This therapy is not widely used at present. There are many immortals in the market, each with its own propaganda. Therefore, we should treat it with a pragmatic attitude and don't follow suit. This is my advice to you. You can also inquire about the relevant issues yourself, and don't listen to others' nonsense.
