What is the difference between red and near infrared light?

by Graham

Both red light at 660 nm and near infrared light at 850 nm have been proven to enhance cellular function.  The main difference is that red light at 660 nm is readily absorbed by skin tissue leading to improved skin health and collagen production.  Near infrared light at 850 nm is invisible to the human eye and penetrates into deeper tissue, leading to benefits like increased muscle recovery and reduced joint pain.
