The science of light
Understand the light.
Good skincare choices begin with good information. A clear introduction to red light therapy, without the noise.
Explore the spectrum
A different kind of light.
Choose a wavelength to see what changes.
525 nmGreen light
One complete wave · wavelength
At 525 nm, green has the shortest wavelength of the four shown. More waves fit into the same distance.
590 nmYellow light
One complete wave · wavelength
At 590 nm, yellow sits between green and red in the visible spectrum. Its wave spacing falls between the two.
660 nmRed light
One complete wave · wavelength
Red light sits at the long-wavelength end of the visible spectrum. The mask’s red LEDs emit at 660 nm.
850 nmNear-infrared
One complete wave · wavelength
At 850 nm, near-infrared sits beyond visible red. You cannot see this wavelength; the pink colour here is a visual guide only.
An illustration of wavelength, not a measurement of skin penetration or treatment results.
More than a red glow.
Red light therapy, also called photobiomodulation, uses red or near-infrared light. It is studied for a range of skin concerns, but devices and treatment protocols vary.
Research on one device cannot establish what another device will do. Wavelength, output, treatment schedule and the person using it all matter.
Keep expectations considered.
At-home devices differ from professional treatments. Results vary, and a particular outcome is never guaranteed. Follow the directions for your device and speak to a dermatologist about suitability.

Beneath the surface
Every light.
Its own journey.
Light interacts with skin in different ways. Explore how wavelength influences its journey beneath the surface.
The wavelength makes a difference.
Shorter visible wavelengths are generally absorbed closer to the surface. Red and near-infrared light can travel relatively deeper. Skin properties and the light source also shape that journey.
525 nm. Green light.
Green is the shortest visible wavelength used in this mask. Its interaction with skin depends on absorption and scattering, as well as the skin itself.
590 nm. Yellow light.
Yellow sits between green and red in the visible spectrum. Its interaction with skin depends on absorption and scattering, as well as the properties of the skin itself.
660 nm. Red light.
Red light has a longer wavelength than green or yellow light. Light is absorbed and scattered as it travels through skin; wavelength is only one part of that process.
850 nm. Beyond visible light.
Near-infrared light is invisible to the human eye. It is shown in rose here so you can follow its path. The illustration represents relative behaviour, not a measured treatment depth.
Illustrates general light behaviour, not measurements of this mask or a promise of results. Penetration varies with skin, wavelength and device settings. Near-infrared is represented in colour for clarity.
