The new techniques to apply laser via intravenous, intraarticular, interstitial or using optic fiber allow the laser beam to get to deep areas of the human body in sufficient concentrations and with high effectiveness. Along with red and infrared beams, we have available green and blue laser beams which do not have deep penetration levels. The Laser Therapy can be applied very close to the injured area and the problem of the superficial absorption is not an obstacle any more for LILT therapy (Low Intensity Laser Therapy).
The Photodynamic Therapy (PDT) for skin tumors, previous administration of a photosensitizer, is focused on the tumors, and after 3 hours, it is activated via a red laser beam radiation of a certain wave length. This allows the physician to carry out the laser beam focalization in sufficient concentrations and directly to the tumor tissue, causing this way the destruction of Reactive Oxygen Species(ROS).
The photosensitizer adheres to the tumour cells (in yellow) to attract the laser beam (in red) in order to destroy them.
LILT – Low Intensity Laser Therapy, helps to decrease pain and inflammation, and accelerate healing via many immune system processes.
