655 Prime (Systemic PBM)

USD $399.00

The Vielight 655 Prime is a compact personal photobiomodulation (PBM) device.

Its cold laser 655nm red beam is ideal for systemic photobiomodulation via photonic diffusion through the nasal blood capillaries.

The Vielight 633 Red and Vielight 655 Prime are comparable in efficacy.

The scientific reasoning behind the difference between the 655 nm and 810 nm wavelengths can be found in this independent study : (Link)

Why intranasal?

The nasal cavity is rich with blood capillaries. There are more capillaries per cm2 than in most organs of the body. Five arteries connect to the nasal cavity, while the Little’s area is a frequent site of nasal bleeding. Given the rich supply of blood and the thin, permeable membrane within the nasal cavity, the light can easily reach the blood. Thus, this area is well-suited for systemic photbiomodulation which via blood.

Vielight’s intranasal PBM devices combine solid state technology with intranasal LEDs. The diode’s transparent high impact polycarbonate enclosure ensures quality and durability, turning this PBM device into a life-long investment.

The Vielight 655 Prime emits low level laser light with a 655 nm wavelength. The beam has a power density of 5 mw/cm2.

The laser beam footprint targets the nasal cavity, which is rich in blood capillaries. The device parameters have been derived from clinical studies on low level light therapy over the last few decades.

IMPORTANT: As a safety measure, please do not look directly into the laser light source, to avoid harming your eyes.
