LED Light Therapy
LED light therapy, also known as photobiomodulation, is a treatment based on the use of certain wavelengths of red or near infrared light to create a range of physiologic effects. This therapy can affect cells and tissues to improve healing, reduce pain and decrease inflammation. In the past, laser therapy has been used extensively in medicine. In more recent years, light emitting diodes (LED) have become more common. The advantages of LED therapy over laser therapy include no laser safelty consideration, ease of use, the ability to treat a large area at once and lower cost.
Specific wavelengths of light cause various biological effects on humans. Over 200 articles have been published on the therapeutic use of red light and near infrared radiation. These wavelengths penetrate through skin and cause a local, and possible systemic, reaction. This therapy affects cell metabolism, cell signaling, the inflammatory process and growth factor production.
During LED therapy, a light source is placed directly near an area of tissue damage, pain or inflammation. The light source is near the skin to allow for penetration of the skin, interaction with the chromophores located in cells, causing changes at the molecular, cellular and tissue level. Light therapy can create a complex physiologic reaction in damages and diseased tissue to accelerate healing and speed tissue regeneration. It also enhanced circulation, reduces acute inflammation, decrease acute and chronic pain and restores normal cellular function.
You should avoid LED therapy if you are taking Accutane, or have an active skin rash. Side effects are extremely uncommon, but can include increased inflammation, local redness and rash.
