Red light
Part of the visible spectrum. Wavelength, dose and the specific application matter.
Light, simply explained.
A practical introduction to red and near-infrared light, without oversized promises.
Near-infrared light
Not visible like red light. Devices often combine it with red-light channels.
Red, near-infrared, and PBM
Red light sits within the visible part of the spectrum. Near-infrared light sits immediately beyond the visible range, so the eye cannot see it. In scientific literature, both are often discussed alongside photobiomodulation, or PBM, a term for studying the ways light may interact with biological systems.
This is not UV light. UV and visible red light occupy different parts of the spectrum, so they should not be treated as the same thing. Nor is PBM a promise of a particular result: it names an area of research, not a universal outcome for every person or every device.
Protocol provides the context
A light routine is not defined by a colour name alone. Wavelengths, intensity, distance, duration, frequency, treatment area, and device design form the context of a protocol. This is why studies, devices, and methods of use cannot simply be laid over one another.
There is no universal number of minutes or schedule for every format. The instructions for a specific device take priority over general tips, and longer use does not by itself mean a better result. Read the stated precautions before your first ritual.
A measured routine
Choose a format that suits the area, space, and habits you can realistically maintain. Then follow the device instructions, including positioning, duration, and frequency. Clear expectations and consistency with the instructions are more useful than comparing yourself with someone else’s routine.
