Vielight 633 Red (Systemic PBM)


Links below open on my website which is dedicated to explaining the science of red light therapy. The Vielight 633 Red (Systemic PBM) is an at-home red light therapy device. The 633 Red applicator delivers continuous wave red light to the dense capillary network in the nasal passages. The photobiomodulated cells travel throughout the circulatory system. Red light delivered to the circulatory system stimulates the immune system and increases blood oxygen levels. Theoretical benefits include increased energy levels and enhanced aerobic fitness. Blood photobiomodulation increases nitric oxide and hemoglobin concentration. Vielight owns the patent for delivering photons to the ventral area through the nasal passage.

Studies at or Near 633 nm Red

We are fortunate that our bodies and brains accept light in a range of wavelengths. Peak absorption wavelength matters less than getting a correct dose of any of a range of wavelengths nearby peak absorption.
