Light therapy has been used by ancient cultures (Greeks, Egyptians, Chinese) for thousands of years. It is only recently that science has been able to explain these healing principals and apply them in a manner that is safe and efficient for healing and anti-aging purposes. Phototherapy is the scientific application of light, to specific points of the body to activate or produce particular physiological results. There is often some confusion, when discussing the behavior of light in tissue. When light is generated, and travels through air, it can be described as being comprised of electro-magnetic waves, measured in nanometers (nm). However, it is the “energy” that we are most interested in. It is the proper combination of energy output, type of light wavelength and absorption of energy in the cell that assists in skin rejuvenation and anti-aging. The activities caused by phototherapy increase vascularity in the formation of new capillaries as well as help to replace damaged ones. Certain wavelengths of light also stimulate the production of collagen. The chemical compound ATP (adenosine triphosphate) is a major carrier of energy in cells and its release allows for a faster acceptance of nutrients in cells and the removal of toxins when stimulated by phototherapy. Increases in lymphatic function also occur with the application of phototherapy.
