For LED treatment, the the depth of penetration is measured by wavelength. The greater the light’s wavelength the greater the penetration into the skin, within a specific area. This means that the more effective the outcomes of the treatment on the face.

Green Light Therapy Devices: Wavelengths Just Too Short

Recent clinical studies have focused on hyperpigmentation, near infrared light energy has been proven to decrease signs of hyperpigmentation because it quickly reaches the dermis and reduces melanocytes that are hyperactive in dermal melanocytes, without causing adverse effects.Green light therapy wavelengths are just too short to reach melanocytes located in the epidermis layer skin.

What the Research Says

This isn’t to say that these findings don’t support the fact that certain dermatologists have achieved positive anecdotal results with green light treatment for treating hyperpigmentation. But, this method of treatment isn’t backed by reliable, peer-reviewed, and published clinical research.

Near-infrared and red wavelengths of light energy are more long that green therapy, and therefore more efficient in reaching the targeted tissues in the treatment of hyperpigmentation.

Learn about the Science behind Skin Health

As the producer of the highest medically endorsed and most prestigious LED light therapy equipment used in medicine aesthetics, chronic pain and medical, we’re committed to learning the science behind low-level light therapy, and to demonstrating its benefits through science-based education.

Common Question Regarding Green Light Therapy

We often get questions about the impact on the green-colored light on hyperpigmentation. It is true that little is known about the use of green wavelengths for Photobiomodulation (PBM).

Therefore, it’s not clinically relevant to utilize green light because we lack evidence-based evidence to confirm its efficacy.

The Exquisite Diffference

In particular to the laser light therapy devices, Exquisite emits three distinct wavelengths that have been scientifically confirmed to trigger an endocrine response within mitochondria and cells: blue (465nm) as well as red (640nm) as well as near-infrared (880nm).

Little Scientific Support for Green Light Therapy

There is no low-level light therapy device that is FDA-approved or has medical CE-Marks for treating pigmentation either with or without application of wavelengths from green.

It’s Just Not Deep Enough

Although green light is more away from harmful UV radiation, it doesn’t penetrate enough into tissue to get into dermal chromophores, the molecules which absorb the energy of light. 

Numerous in vitro studies have shown that green light may stimulate the hepatocytes, fibroblasts (Castro 2003) neurons, adipocytes, and neurons (Roche 2017 ), adipocytes (Roche Jackson 2013) as well as mitochondria (Kassak 2005) and more. However, scientists are waiting for a convincing confirmation of its clinical efficacy and the efficacy of treatment.

Obstacles to Absorption

In the use of light therapy, absorption the energy of light is essential for positive results. If there isn’t absorption of the light energy, there will be no impact for the face.

Follow the Science for Great Skin Health

Contrary to red and blue the reality that green wavelengths are not long enough to reach the cells of that dermal part of skin one reason why green light isn’t a suitable wavelength for LED treatment. Another major obstacle to the absorption of green light can be hemoglobin (Hb).

Based on the research of Dr. Daniel Barolet’s article”Light-Emitting Diodes (LEDs) in Dermatology1, “Two major wavelength limitations exist for LEDs in the spectrum of wavelengths that are less than 600 nm blood hemoglobin (Hb) is the main barrier to absorption of photons …”.

Clinically Proven Results for Healthy Skin

In essence, it is from the epidermis up to the subcutaneous layer. the root of the problem is a deficiency in mitochondrial functions (that is that cells aren’t producing the energy necessary to maintain normal cell activity), Exquisite light therapy devices have been clinically proven to supply the energy cells require to increase ATP production and return working.

In the field of medical aesthetics, it is the practice of treating of a variety of conditions that are common, such as the treatment of wrinkles, acne and chronic pain, as well as hair loss, in addition to improving circulation and reducing inflammation.

Buyer Beware

Beware of businesses that claim to treat pigmentation using Green light wavelengths. Any claim that the effectiveness of green light can be achieved through red + near-infrared light wavelengths, which are able to get to the cells deeper within the tissue.

Highlighting New Green Light Therapy Research

Studies published in the latter half of 2020 has green light exposure showing potential for treating chronic pain, particularly migraine headaches, as well as the crippling pain they cause.

The article, “Evaluation of green light exposure on headache frequency and quality of life for sufferers of migraine: A first one-way cross-over study,” was published online by Cephalalgia The publication of the International Headache Society.

Based on the Migraine Research Foundation, migraine headaches are the third-most common illness in the world, affecting about 39 million people across the U.S., with crushing discomfort and reduced productivity.

Green Light Therapy Migraine Study

Researchers at researchers from the University of Arizona recruited 29 patients (seven who suffered from episodic migraine) and 22 suffering from persistent migraine. The study “used an one-way cross-over study comprising exposure for 1 to 2 hours every day to diodes emitting white light for 10 weeks. Then, there was two weeks of washout, and then exposure of 1 to 2 hours daily to green light emitting diodes over 10 weeks.

Patients were allowed to continue with current treatments and begin new treatments in accordance with the directions of their physician. Results were measured through surveys of patients. The main measurement of the outcome was number headache-related days per month.

Secondary outcome measures comprised of changes in frequency and intensity of headaches over the course of two weeks as well as other indicators of quality of life, such as the ability to fall asleep, sleep, as well as capacity to do work. The effects of pain medication were analyzed to determine the possibility of reduction.”

Promising Results for Migraine Pain Relief

The findings were as following: “When seven episodic migraine and 22 chronic migraine sufferers were studied as separate cohorts, the study found that white light emitting diodes did not cause significant difference in the frequency of headaches for either chronic migraine patients or chronic migraine sufferers.

The data from both the chronic migraine and episodic migraine groups revealed that diodes emitting white light resulted in a tiny but statistically significant reduction in the number of days with headaches from (days + SEM) 18.2 1.8 to 16.5 2.01 days. 

The green light-emitting diodes led to significant reductions in the number of headache days, between 7.9 1.6 and 2.4 1.1 and between 22.3 1.2 up to 9.4 1.6 in migraine patients with episodic attacks and chronic migraine sufferers, respectively.

Some improvements in secondary outcomes were seen with white diodes emitting light, there were more secondary outcomes of significantly greater scale, such as assessments of the quality of life, the Short-Form McGill Pain Questionnaire, Headache Impact Test-6, and a Five-level variant of EuroQol five-dimensional questionnaire without any reported adverse effects were observed with the use of green diodes that emit light.

Conclusions about the effectiveness of pain medications using green light emitting diode exposure are not feasible. The light therapy did not cause any adverse side effects. therapy were noted. The patients had reported the need to start new therapies.”
