What is the difference between red and near infrared light?
Red and near infrared (NIR) light are both in the natural light spectrum and have been clinically proven to enhance cellular function. The main differences are 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.
