Specific to our LED light therapy machines, Celluma emits three discreet wavelengths that are scientifically proven to effect a therapeutic response inside our cells via mitochondria and cell membranes: blue (465nm), red (640nm), and near-infrared (880nm).

Team Celluma is a devoted squad of individuals with a shared dedication to global wellness and deeply inspired by light and its power to transform lives. We're passionate about making the world a better place by providing solutions that improve the health and wellbeing of people worldwide.

Unlike blue and red, yellow, and green light wavelengths have little or no scientific evidence to support their use which is why we choose not to use them in Celluma devices.

However, as a science-based company, we understand that new evidence is published all the time. If you have any credible scientific evidence to support otherwise, please pass it along!

According to Dr. Daniel Barolet’s paper, Light-Emitting Diodes (LEDs) in Dermatology¹, “Two major wavelength boundaries exist for LED applications: at wavelengths under 600 nm, blood hemoglobin (Hb) is a major obstacle to photon absorption…”.

When it comes to light therapy, absorption of the light energy is crucial to positive outcomes. If there is no absorption of the photonic energy, then there will be no effect on the skin.

Combining data from the episodic migraine and chronic migraine groups showed that white light emitting diodes produced a small, but statistically significant reduction in headache days from (days ± SEM) 18.2 ∓ 1.8 to 16.5 ∓ 2.01 days.

While some improvement in secondary outcomes was observed with white light emitting diodes, more secondary outcomes with significantly greater magnitude including assessments of quality of life, Short-Form McGill Pain Questionnaire, Headache Impact Test-6, and Five-level version of the EuroQol five-dimensional survey without reported side effects were observed with green light emitting diodes.

Here at BioPhotas, we are driven by research.  As the use of green wavelengths is not clinically supported,  it is therefore not clinically relevant to use green light until there is evidence-based proof to validate its efficacy.

Research published in late 2020 shows green light exposure exhibiting promise in the treatment of chronic pain, specifically migraine headaches and the often-debilitating pain they can cause.

This exercise will show how to make objects inside a room emit light and the basics of working with emissive material in Unity to create indoor illumination. For this exercise we are going to make the emissive objects be the only source of light within the room.

Several in vitro studies show that green light can stimulate fibroblasts, hepatocytes (Castro 2003), neurons, adipocytes (Roche 2017, Jackson 2013), mitochondria (Kassak 2005), etc.

Conclusions regarding pain medications reduction with green light emitting diode exposure were not possible. No side effects of light therapy were reported. None of the patients in the study reported initiation of new therapies.”

Green lighttherapy benefits

Although green light is further away than blue from harmful UV ionizing radiation, it does not penetrate deep enough in tissues to reach dermal chromophores; the molecules that absorb light energy.

Green light emitting diodes resulted in a significant decrease in headache days from 7.9 ∓ 1.6 to 2.4 ∓ 1.1 and from 22.3 ∓ 1.2 to 9.4 ∓ 1.6 in episodic migraine and chronic migraine patients, respectively.

The paper, “Evaluation of green light exposure on headache frequency and quality of life in migraine patients: A preliminary one-way cross-over clinical trial,” was published online by Cephalalgia, the journal of the International Headache Society.

We are frequently asked about the effect of different wavelengths of light energy, including the use of green light to treat hyperpigmentation. The fact is that very little has been published on the use of green wavelengths in photobiomodulation (PBM).

In medical aesthetics, this applies to the treatment of a multitude of common conditions, including treating acne, wrinkles, managing chronic pain and hair loss, as well as increasing circulation and decreasing inflammation.

When it comes to effectiveness in LED light therapy (also known as photobiomodulation, or PBM), it is important to utilize wavelengths capable of reaching the target cells.  If the target cells are not reached, then there will be no therapeutic effect.  Depth of penetration is determined by wavelength. The longer the wavelength of light energy, the deeper the light reaches into the tissue, within a well-defined range. Thus, the better the treatment results for the condition being treated.

The results were as follows: “When seven episodic migraine and 22 chronic migraine patients were analyzed as separate cohorts, white light emitting diodes produced no significant change in headache days in either episodic migraine or chronic migraine patients.

Essentially, from the epidermis to the subcutaneous layer, where the root cause of the condition is compromised mitochondrial function (that is to say, when cells are not producing the energy required to drive normal cellular activity), Celluma light therapy devices are clinically proven to provide the energy that cells need to increase ATP production and get back to work.

Patients were allowed to continue current therapies and to initiate new treatments as directed by their physicians. Outcomes consisted of patient-reported surveys. The primary outcome measure was the number of headache days per month.

Secondary outcome measures included patient-reported changes in the intensity and frequency of the headaches over a two-week period and other quality of life measures including ability to fall and stay asleep, and ability to perform work. Changes in pain medications were obtained to assess potential reduction.”

We urge you to beware of companies purporting to treat pigmentation with green light wavelengths. Most claims of green light’s effectiveness has been shown, via scientific research, be achievable by red + near-infrared which have the capability to reach the target cells located deeper in the tissue.

Red and near-infrared wavelengths of light energy are longer than green light wavelengths and therefor more effective in reaching the target tissue in the dermal skin layers.

In fact, no low-level light therapy device is FDA-cleared or has a medical CE-Mark for treating pigmentation with or without the use of green light wavelengths.

These findings do not negate the fact that some skin care professionals report favorable anecdotal results using green light therapy for the treatment of hyperpigmentation. However, anecdotal reporting does not equate to robust, peer-reviewed and published clinical data.

Researchers from the University of Arizona recruited 29 patients (seven with episodic migraine and 22 with chronic migraine headaches. The study, “used a one-way cross-over design consisting of exposure for 1-2 hours daily to white light emitting diodes for 10 weeks, followed by a 2-week washout period followed by exposure for 1-2 hours daily to green light emitting diodes for 10 weeks.

According to the Migraine Research Foundation, migraine headaches are the third most prevalent illness worldwide, impacting approximately 39 million people in the U.S., with crushing pain and loss of productivity.

In recent clinical studies on hyperpigmentation, near-infrared light energy was demonstrated to reduce the appearance of hyperpigmentation.  It reaches into the dermis, down-regulating hyperactive dermal melanocytes without side effects.

As the manufacturer of the most medically credentialed and most awarded LED light therapy device in medical aesthetics and chronic pain management, we are committed to understanding the science of low-level light therapy and sharing its benefits though science based education.

Unlike blue and red, the fact that green wavelengths are too short to reach cells in the dermal layer of the skin is only one reason that green light is not a valuable wavelength for LED therapy. Another serious obstacle to the absorption of green light energy is hemoglobin (Hb).
