What is the wave length of the Photon function?
It is called monochromic because all the light energy is concentrated on one wavelength of visible red light.
It is great for photon therapy with red light, which penetrates several mm deep into the surface layer of the skin and has been shown to improve microcirculation. There are also many studies on Pubmed about the healing potential of visible red light for nerve regeneration.
660nm Red LEDs light therapy is now considered great for skin anti-aging and improvement. A 1-hour session length is optimal for this, and one should use a bare mat and skinny clothes that light can penetrate.
There is a lot of info on studies like red light’s benefits for immunity, nerves, and joint health.
