Class IV cold lasers utilize photons to accelerate cellular reproduction and growth of cells. This occurs by the photons initiating a higher output of specific enzymes, greater oxygen and food particle loads for blood cells and thus greater production of basic food source for cells, ex. ATP ( adenosine Tri- Phoshate.) The cold laser photons also stimulate fibroblast development and accelerate collagen synthesis in damaged tissues along with induced temporary vasodilation to increase blood flow, thus increasing your healing potential. The photons also reduce swelling in and around joints increasing mobility and decreasing pain. Cold laser reduces fibrous tissue formation by reducing scar tissue formation following damage from cuts, scratches, burns and even post surgery. Another added benefit from a class IV cold laser is the photon exposure speeds up the process of nerve cell reconnection to bring a numb area back to feeling.
