Precise LED vs Laser
REVIAN does not use lasers; REVIAN only uses precision LEDs (119 in total). We use LEDs primarily because they enable us to dial-in the precise nanometer of wavelength necessary to trigger the mechanisms of action in cells. Our independent research and clinical trial has shown our combination of 620 and 660 nanometer wavelengths activate more biological changes in the cells to renew their vitality than lasers. Laser products use a more generic red wavelength of around 660 nm that is not as effective by itself.
The results that you see on our clinical results page are the top-line results from our recently completed trial. You can see some of our early images at grow. REVIAN.com.
The second reason is that LEDs emit a much wider angle of light, bathing the scalp in overlapping cones of light. Laser products are much more tightly focused and only target discrete spots on your scalp. We’ve proven that our LED light penetrates the skin fully to the needed levels to affect the cells, but with more complete coverage compared to laser diodes. You’ll find REVIAN's competitors offer higher-priced models with higher quantities of laser diodes that still do not offer the same level of complete coverage as REVIAN.
Third, our LEDs are light and thin. This allows our cap to be much more flexible, lightweight, and moves our light sources further away from the scalp to provide even more coverage.
