Frequently Asked Questions About PhotoMedicine

How does PhotoMedicine work?

Every human cell contains organelles called mitochondria, which generate the energy the cell needs to survive, as well as help cells communicate with each other to work more efficiently.  Research has suggested that for in vitro cell systems, the process of generating the energy can be stimulated and enhanced by providing additional energy to the cell in the form of light energy. To learn more about the basic physics of light, and this mechanism called photobiomodulation, visit the section titled, What is Light Therapy?.

What makes LED PhotoMedicine devices special? Can’t a person simply sit in the sun?

The sun emits a very broad spectrum of electromagnetic energy, ranging from beyond infrared to beyond ultraviolet. Most of this energy doesn’t reach the Earth, and much of it can be harmful in large doses. Only a little bit of this energy spectrum is in the optimal range for photobiomodulation, and that is delivered at very low power.

The LED PhotoMedicine devices being developed by QBMI can deliver up to 12 times the amount of pure light energy of the sun at 830nm.  Basically, to get the same amount of energy and the same effect as a QBMI LED PhotoMedicine device, one would have to sit in the sun for a much longer time, at risk from the damaging effects of other bands of electromagnetic radiation.

Can I use an LED PhotoMedicine device at home?

A properly designed LED device will be safe and easy to use at home. Equipped with a push-button “Start” button and automatic timer, you will receive the appropriate dose in each treatment session. The device stays cool, eliminating the risk of tissue damage. No special training will be required to use the device.

Aren’t lasers the most advanced light technology?

Light is light ... the key is how that light is delivered. Lasers are coherhent light (highly focused beams of light, with a very narrow bandwidth). They can also damage tissue if not used properly, therefore requiring special trained personnel to administer. A properly designed LED device is more effective, covers a broader area of tissue and emits light in the optimum broad spectrum. Learn more about the difference between LEDs and lasers here.
