The Science Behind How Laser Therapy Works:

Laser therapy is a medical treatment that uses focused light to stimulate a process called photobiomodulation (PBM). During PBM, photons enter the tissue and interact with the cytochrome c complex within mitochondria. This interaction triggers a biological cascade of events that leads to an increase in cellular metabolism, which can decrease pain as well as accelerate the healing process.

Photobiomodulation therapy is defined as a form of light therapy that utilizes non-ionizing light sources, including lasers, light emitting diodes, and/or broadband light, in the visible (400 – 700 nm) and near-infrared (700 – 1100 nm) electromagnetic spectrum. It is a nonthermal process involving endogenous chromophores eliciting photophysical (i.e., linear and nonlinear) and photochemical events at various biological scales. This process results in beneficial therapeutic outcomes including but not limited to the alleviation of pain, immunomodulation, and promotion of wound healing and tissue regeneration. The term photobiomodulation (PBM) therapy is now being used by researchers and practitioners instead of terms such as low level laser therapy (LLLT), cold laser, or laser therapy.

The fundamental principles that underpin photobiomodulation (PBM) therapy, as currently understood in the scientific literature, are relatively straightforward. There is consensus that the application of a therapeutic dose of light to impaired or dysfunctional tissue leads to a cellular response mediated by mitochondrial mechanisms. Studies have shown that these changes can impact pain and inflammation, as well as, tissue repair.

Stimulate Cytochrome C

The primary target for the photobiomodulation process is the Cytochrome C complex, which is found in the inner membrane of the cell mitochondria. Cytochrome C is a vital component of the electron transport chain that drives cellular metabolism.

Increase Production of ATP (Energy)

As light is absorbed by Cytochrome C oxidase (COX), it stimulates the electron transport chain to increase the production of adenosine triphosphate (ATP) within the mitochondria. When tissue is damaged, the production of ATP in the cell is impaired which slows down the metabolism of the cell as a protective mechanism. PBM helps restore the oxidative process which helps restore normal cellular function.

Increase NO and ROS Activity

In addition to ATP, laser stimulation also produces free nitric oxide (NO) and modulates reactive oxygen species (ROS). NO is a powerful vasodilator and an important cellular signaling molecule involved in many physiological processes. ROS have been shown to affect many important physiological signaling pathways including the inflammatory response. Together, increased NO and improved ROS levels provide an environment for faster signaling, resulting in decreased inflammation.

Restore Cellular Energy Balance

PBM helps restore normal cellular function which helps prevent apoptosis (cell death). This helps reduce inflammation, edema, and hastens the tissue repair process.


For PBM to occur, light needs to reach the mitochondria of the damaged target tissue. When laser therapy is applied to the surface of the skin the best results are achieved when a sufficient amount of light (number of photons) reaches the target tissue. There are a number of factors that can help maximize the light that reaches the target tissue, including:

  • Light Wavelength
  • Minimizing Unwanted Absorption
  • Power
  • Reducing Reflections
