The semiconductor laser therapy device applies 650nm-wavelength low-intensity laser to irradiate radial artery, ulnar artery, neiguan acupoint, daling and jianshi acupoint and nasal cavity, through low-intensity laser light irradiation to produce a series of energy effects and biological effects, which can change the blood rheology, reduce blood viscosity, reduce the body molecules, promote microcirculation, thereby improving the oxygen carrying capacity and the deformability of red blood cells, and finally achieving auxiliary treatment effect on hypertension, hyperlipidemia, cardiovascular and cerebrovascular diseases. In a similar way, it also has good curative effect of treating acute rhinitis, chronic rhinitis and nasal sinusitis simultaneously.  

Through the low intensity laser wavelength of 405 nm irradiation on skin, LED blue light can inhibit inflammation rapidly. During the process of the formation of acne, the main reason is caused by propionibacterium. Led blue light can destroy the bacteria, minimize the formation of acne without cause any damage or harm to skin tissues.
