What does nm mean on an LED face mask?
Nanometres (nm) describe the light's wavelength. Visible red, blue and near-infrared occupy different parts of the light spectrum. Compare wavelengths alongside the mask's format, session length and controls.

Manufacturer-listed specifications: NOIR laser + LED version and SOFT silicone LED mask. LED chips and light positions are different measures. Follow the supplied instructions.
Red, blue and near-infrared are not interchangeable
Visible red and blue wavelengths are distinct parts of the light spectrum. Near-infrared sits beyond the visible red range. Some LED masks combine more than one type of emitter, but there is no simple rule that 'more wavelengths' automatically means a better product.
Why optical output matters more than a big LED number
When comparing light specifications, consider irradiance (mW/cm²), energy per session (J/cm²), distribution, session length and the supplied instructions. Fit, controls and comfort also help determine which format suits your routine.
Does this prove visible skin improvement?
Wavelength is one product specification. Compare the mask's format, fit, controls, charging and supplied instructions alongside the light specifications.
