Do all red lights work the same?

Studies have shown that red light therapy is good for health and is most effective in the 600 nm-850 nm range.

The red spectrum extends from approximately 620 nm to 750 nm. The wavelengths of red light with the most scientifically proven advantages are 630 nm and 660 nm. Near-infrared light starts at 750 nm and extends to 1,200 nm. The near-infrared wavelengths scientifically proven to be beneficial to humans include 810 nm, 830 nm, and 850 nm.

Wavelengths outside these ranges can quickly reduce their ability to penetrate and absorb. Not only that, but certain red and near-infrared wavelengths are also thought to provide unique healing and regeneration effects to the body and brain. Various published scientific studies have shown that near-infrared light in the lower range can penetrate the human body and bones more efficiently than at higher wavelengths. These two absorption regions from 620nm-660nm and 800nm-850nm are called "active regions".

As you may already know, both 660nm and 850nm wavelengths have been widely proven to provide a wide range of skin and deep tissue therapies, but 630nm, 810nm and 830nm wavelengths also bring many benefits for health and well-being. One of the world's leading experts in red light therapy and near-Infrared Light Therapy conducted research and reviews and proved that the near-infrared wavelengths of 810nm and 830nm have an incredible ability to penetrate the skull while targeting the brain, while the 630nm red The wider wavelength range has great cellular benefits in the upper skin area.
