Superluminous light-emitting diodes in the therapy pads giving off infrared rays, which lights at a wavelength of 850-950nm, could be applied to skin directly.

vThe infrared rays absorbed by body cells could promote angiectasis and improve local blood circulation.

vImprovement of blood circulation can accelerate wound healing, relieve pain and has good effect on peripheral neuropathy. 

Monochromatic infrared ray with wavelength of 850-950nm can penetrate 5cm to hypoderm, be absorbed by red blood cells and make NO release locally.

vMoreover, NO is very good at removing swells, reducing inflammation, accelerating the concrescence of the wounds and promoting bone formation.
