How Red Light Works
Red light is not simply about using the brightest device or the
longest session. The experience depends on the wavelength,
light output, treatment distance, and total delivered dose.
01
Deliver
LEDs deliver selected red or near-infrared wavelengths to
the intended area. Device design, coverage, and treatment
distance affect how much light reaches the skin.
02
Absorb & Respond
Part of the light energy is absorbed by tissue and may
interact with cellular processes involved in energy
production and normal recovery responses.
03
Control the Dose
Total dose depends on irradiance and session time. More
intensity or longer sessions do not automatically mean
better results.
Wavelength
The type of light delivered.
Irradiance
The light power reaching the target area.
Session Time
Works with irradiance to determine total dose.
