What is Green Light Therapy?

Green light therapy is a light treatment that uses specific wavelengths of green light to promote collagen production, improve energy levels, and reduce inflammation.

Like any other LED light therapy, green light therapy uses a well-calibrated wavelength of light to ensure that the targeted light energy reaches the skin for optimal health benefits.

It should also increase your overall understanding of how the LED treatment works, the health benefits, and how to use it, among other things.

How Does Green Light Therapy Work?

In precise, green light therapy deploys the use of a range of wavelengths of about 525-550 nanometers (nm) to deliver the required light energy to the skin. Immediately the light energy penetrates the skin, it stimulates a number of the body’s cellular processes so that it can offer the necessary therapy health benefits.

Green light therapy works by utilizing specific light wavelengths to target the body’s tissue and cells. This helps boost collagen synthesis, improve energy levels, and reduce inflammation and pain for the body’s overall health and well-being.

A study published in the Journal of Pain looked into the effect of red light therapy in alleviating inflammation and post-surgical pain.

Green light therapy also works via a primary mechanism involving the stimulation of the body’s tissue and cells to increase collagen production and photosynthesis essential for maintaining healthy and youthful skin.

A research study published in BMJ Open Journal was conducted to establish the effects of green light therapy on collagen synthesis. The results of the study indicate that body exposure to green light of wavelength ranging from 500-570nm has been shown to induce fibroblast proliferation and the production and maturation of collagen fibers.

Green light therapy has also been found to reduce pain and inflammation, making it an ideal treatment option for those fighting acute or chronic pain. Research published in Cephalalgia: An International Journal of Headache shows that exposure to green light-emitting diodes was able to significantly reduce the number of headache days in people with chronic or episodic migraine conditions.

Green light therapy also works from the inside out to provide the skin with numerous skin health benefits. The light penetrates the skin to target the pigmentation of skin cells and prevent them from moving to the skin’s surface.

According to a study published in the Journal of Clinical and Aesthetic Dermatology, Phototherapy through LEDs can be used to treat and manage a number of aesthetic and medical conditions in the field of dermatology. LED phototherapy has also been identified as the best option for rejuvenating aging skin.
