The laser’s anti-inflammatory effect accelerates wound regeneration and alleviates pain in a given area.
During the process of wound healing, the cellular mechanism becomes activated on a molecular level. This initiates a series of chain reactions, which involve a large number of intracellular molecules, as well as molecules that make up the extracellular fluid. Hemoglobin, melanin and cytochrome c oxidase are only some of the molecules that stimulate the production of collagen, the protein crucial for wound regeneration. Laser beams accelerate the production of collagen and, consequently, wound healing, by means of photoactivation.
They cause the increase in the inflammatory mediator concentration and the blood flow, thus reducing inflammation.
The exact mechanism according to which laser beams remedy pain has never been fully explained. However, we do know that they affect the production and the emission of pain mediators systemically and locally within the tissue, boost endorphin production and lower nerve-ending activity, which increases pain tolerance.
