Red light therapy explained

Discover how CellLight™ technology is designed around cellular energy, long-term wellness and longevity.

Photobiomodulation

PBM

also known as red light therapy

safe, non-invasive technology that uses specific wavelengths of red and near-infrared light to interact with cells and tissues in the body.

A visible light with wavelengths between 620–750 nm, suited to targeted light use and cosmetic skincare routines.

An invisible light with wavelengths between 700–1000 nm, suited to focused light use and everyday wellness routines across larger body areas.

The smallest units of life in the body, performing essential tasks to keep us healthy and functioning.

Mitochondria

are the powerhouses of our cells.

are the powerhouses

Red light helps it enhance its energy production, supporting overall cell function.

Light penetration

Red light (500-600 nm) and near-infrared light (800-1000 nm) penetrate the skin, reaching deeper layers of muscle and tissue. This light stimulates the mitochondria within cells, the energy-producing organelles, directly influencing the citric acid cycle.

Cellular stimulation

When absorbed by mitochondria, light may interact with processes involved in ATP (adenosine triphosphate) production, the body’s primary cellular energy carrier.

Boost and regeneration

In photobiomodulation research, ATP production and cytochrome c oxidase activity are considered key cellular mechanisms, forming the scientific foundation for light-based routines around wellbeing, sleep, skincare, longevity, and resilience.

When mitochondria function well, cells have a reliable supply of ATP for everyday activity. This supports the many cellular functions involved in energy, focus, and physical wellbeing.

If mitochondria struggle, less cellular energy may be available. This is one of many factors that can influence everyday energy, focus, and how the body feels.

Red light therapy explores how red and near-infrared light interact with mitochondrial processes involved in cellular energy.

Red and near-infrared light work in unique ways. We guide you in building a routine tailored just for your needs.

We developed CellLight™ to combine red and near-infrared wavelengths in flexible settings for different light routines, coverage areas, and everyday wellness preferences.

Red light is suited to surface-focused cosmetic skincare routines, while near-infrared light penetrates more deeply and is designed for focused or larger-area post-workout wellness sessions.

Four factors shape every light session: wavelength, session length, distance from the device, and light intensity. Always follow the guidance provided for your specific product.

Wavelength selection

Choose between red light, near-infrared light, or a combination of both, depending on the mode and routine you would like to use.

Session length

Session length depends on the device, selected mode, distance, and application area. Follow the product-specific guide within our Members Area for the recommended duration.

Distance from the device

As a general starting point, position yourself around six inches from the device, then adjust within the recommended range for your setup and routine.

Exploratory self-observation with a machine-learning expert, 2021

Research question: What changes in HRV were observed alongside consistent red-light use?

Observed result: HRV increased by 122% during the documented observation period.

Exploratory case report with FertiSuisse, 2023

Research question: What changes in endometrial thickness were observed alongside red-light use?

In this individual case, endometrial thickness increased by more than 100% during the observation period. The participant later became pregnant.

Observational pilot with FFG Austria and Kinderwunschinstitut Dr. Schenk, 2024–2026

Research focus: Exploring photobiomodulation in women with chronically thin endometrium.

In this observational cohort (n=12), changes in endometrial thickness were documented alongside PBM use.

The Scientific journey of Luminous Labs

two women are talking to each other, both of them sitting on a cozy lounge chair facing each other, the women on the right explains something to the women sitting on the left, there is a red glow behind them, it is a luminous labs red light therapy panel

hands are covering a lower abdomen, as red light shines onto the abdomen, we can also see a black red light therapy panel facing the belly

a group of people is looking at a person presenting something and listening carefully, the room is illuminated in a red glow from a luminous labs red light therapy panel

there is a very high end bedroom and facing the bed is a full-body red light therapy se-tup from luminous labs, it hangs on the wall and you can see a window with morning light on the outside as well
