Intranasal 633 Red

The Vielight 633 Red is a compact personal photobiomodulation (PBM) device.
Its 633nm cold red beam is ideal for systemic photobiomodulation via photon diffusion through nasal blood capillaries.
Vielight 633 Red and Vielight 655 Prime are comparable in effectiveness. The nasal cavity is rich in blood capillaries.  There are more capillaries per cm 2 than in most organs in the body.  Five arteries connect to the nasal cavity, while Little’s area is a frequent site of nosebleeds.  Given the rich blood supply and the thin, permeable membrane inside the nasal cavity, light can easily reach the blood.  Thus, this area is suitable for systemic photobiomodulation via blood.
