What is Photobiomodulation and Low Level Light Therapy?
Imagine if you could get all of the benefits of the sun, deep within the body, without the harmful ultraviolet rays. That's one of the easiest ways to explain how Low Level Light Therapy benefits the body.
Near-Infrared (NIR) polychromatic spectrum has been well studied since 1960s and have been documented through thousands of fundamental research studies to analyze the effects of NIR on tissue repair and rejuvenation, as well a pain relief mechanisms. NIR photobiomodulation therapy is a non invasive, and highly effective adjunct therapy in the field of prevention as well as in healing..
Effective photomodulation wavelengths ranging from 633nm to 1128nm are employed for the maximum penetration depth to be effective on the fibroblasts in the soft tissue and osteoblasts in the bones.
What are Some of the Conditions Low Level Therapy can Treat?
- Back and neck pain
- Carpal Tunnel Syndrome
- Cronic Inflammation
- Diabetic neuropathy
- Knee pain
- Muscle spasms and stiffness
- Plantar fasciitis
- Ruptured tissue, tendons and ligaments
- Tennis/Golfers Elbow
- Wound healing and clot formation
...The super-pulsed GaAs (diodes) in GaAs lasers give deep penetration without the unwelcome effects of Continuous Wave (lasers) such as thermal damage, as well as allowing for shorter treatment times.

In Technical Terms, This is How it Works
Dilation of partially obstructed blood flow vessels to transport higher volume of oxygen and nutrients for the initial therapy to begin.
Cytochrome-C oxidase (COX) is a large trans membrane protein of the inner mitochondrial membrane. Irradiation of COX increases the activity of the mitochondrial respiratory chain producing more adenosine triphosphate (ATP). NIR irradiation may increase the amount of available COX over time.
Higher ATP amount triggers viable proliferation of fibroblast cells for increased collagen fibers, elastin and fibrin.
Antibacterial effects by induction of reactive oxygen species (ROS).
ROS are involved in cell signaling, enzyme activation, nucleic acid synthesis, protein synthesis, and the activation of transcription factor.
Anti-inflammatory effects of NIR therapy can be explained by inhibition of prostaglandine, interleukin, and cytokine in cell models.
Increased platelet activity for faster wound closing
adhesive protein delivery to the inflammation site.
Quicker re-epithelization for covering the open wounds, scar formation
NIR released NO (nitric oxide)induces endothelial cell migration by activating growth factors and improved perfusion.
Homeostasis followed by ANGIOGENESIS
NIR light spectrum also increase the diameter and blood flow velocity of the peripheral arterioles and will enhance the microcirculation.
Increased speed of mitosis, facilitating cell multiplication to aid in new vessel formation.
Viable proliferation of fibroblast cells-stimulation of cell division and cell growth of fibroblasts plays an important role in wound healing.
Wave Lengths and Their Benefits
Below are some of the magical wavelengths that stimulate healing and regeneration that are used in our Low Level Light Therapy devices:
633nm: Targets cells to create healthy tissue that resist pathogens at shallow levels
660nm: Excellent with pain reduction and skin tightening
712nm: Deeper tissue fibroblast stimulation, ATP increases
812nm: Targets the enzymes to accelerate the healing process
875nm: Excellent with stimulating the lymphatic system
905nm: Targets the hemoglobin to release more oxygen to the tissue
1128nm: Increases blood flow, and reaches deep tissue delivering nutrients and eliminating waste
Is Low Level Light Therapy Safe?
Yes, Low Level Light Therapy is completely safe, drug-free and non-invasive. All of our devices have an FDA Clearance and CE certification, a mark of European safety and legal compliance. However, it is recommended that the devices not be used directly on any neoplasmic tissue. Pregnant women should refrain from laser treatments applied directly to the abdomen. Also people with pacemakers should not use laser treatments near the heart. The only known side effects at this time is that some medications can cause photosensitivity that can lead to sunburn-like symptoms, a rash, or other unwanted side effects.
How Deep Into the Tissue Can the Light Penetrate?
The level of tissue penetration by the light depends on the beam’s optical characteristics, as well as on the concentration and depth of the chromophores, which are absorbed at different percentages according to the laser light’s wavelength. For instance, water absorbs almost 100 percent of the laser irradiation at 10,600 nanometers, the wavelength of a CO2 gas laser. That is the reason why this type of laser wavelength is used in surgical applications.
Other factors affecting the depth of penetration are the technical design of the device and the particular treatment technique used. There is no exact limit with respect to the depth penetrated by the light. The laser light gets weaker the further from the surface it penetrates where eventually the light intensity is so low that no biological effect from it can be measured.
In addition to the factors mentioned, the depth of penetration is also contingent on tissue type, pigmentation and foreign substances on the skin surface such as creams or applied oils. Bone, muscles and other soft tissues are transparent to certain laser lights, which means that light can safely penetrate these tissues. The radiation in the visible spectrum, between 400 and 635 nanometers, is absorbed by the melanin. In the infrared, a narrow band, which extends approximately from 650 to 1,200 nanometers, is the so-called “therapeutic window”. That is the reason why our devices have wavelengths within the 600-1,200 nanometer.
The lower the light wave the shallower the penetration. The higher the light wave within this therapeutic window, the deper the penetration. Depending upon the tissue being penetrated, our devices can reach between 2.75" and 5", which typically is sufficient to stimulate healing and pain relief of most conditions noted above.
