What is Green Light Therapy?

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 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.
