Systemic Photobiomodulation

Vielight technology internalizes the benefits of photobiomodulation, by directing photons into the circulatory system through the intranasal channel.

By utilizing red wavelengths, the Vielight 633 and Vielight 655’s beams disperse into and are absorbed by the dense network of blood capillaries inside the intranasal channel.

Theoretical benefits include :

  • Improved energy levels

  • Increased oxygenation


  • Improved mood and energy levels

The theory of photobiomodulation proposes the release of nitric oxide(NO) within blood capillaries. The most important function of NO is vasodilation, causing blood vessels to relax and widen. This leads to improved mood and energy levels.

  • Increased oxygenation

Photobiomodulation of the blood has been shown to increase oxygenation and hemoglobin concentration (Δ[HbO]) within stimulated areas, as the electromagnetic energy dose accumulates over time.

By irradiating the nasal cavity, saturated with permeable blood vessels, blood photobiomodulation can be achieved non-invasively.

The Vielight 633 Red is a compact personal photobiomodulation (PBM) device. Its 633 nm wavelength is ideal for systemic photobiomodulation.

The LED of the Vielight 633 Red releases non-coherent cold LED light that is bright red and visible to the human eye.


Similar to the Vielight 633 Red, the Vielight 655 Prime emits a powerful beam within the visible red range in the electromagnetic spectrum.

However, the Vielight 655 Prime utilizes a cold laser beam instead of a LED beam. The efficacy is theoretically similar between the two models.
