Precise LED vs Laser - Revian only uses precision LEDs (119 in total) for a couple reasons: We use them primarily because we can dial in the precise nanometer of wavelength that we want to actually trigger the mechanisms of action in the cells. Our independent research and clinical trial has shown our combination of 620 and 660 activates more biological changes in the cells to renew their vitality. Laser products use a more generic red wavelength ranging 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 the viewing angle that the light is distributed from an LED. LEDs put off a much wider angle of light, bathing the scalp in overlapping cones of light. Laser products are much more tightly focused and only hit spots on your scalp.
Third, the 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.
