What Happens During Low Level Laser Therapy

In all forms of LLLT, tissue is targeted by light energy at a very specific wavelength. The targeted tissue molecules absorb the light energy at a cellular level, resulting in an increase of energy within the cells. This excess energy has to be “worked off” through a series of adaptive changes, which are usually both chemical and physical.Dependent upon the wavelength used during treatment, these changes can have a permanent biological effect on the surrounding cells and tissue. As these changes are caused by a type of phototherapy, the physical changes are referred to as being caused by “photo physics” and chemical changes as “photochemistry”. The resulting effects on the tissue and cells are known as photobiomodulation.
