Red light therapy in particular, is accomplished by specific wavelengths directed through PDT devices. One of its main cellular effects is increasing the production of the adenosine triphosphate , when red light is absorbed by skin cells, mitochondrial action is enhanced. The cellular energy level was found to be more excited in a healed state as opposed to the unhealed status, which means that if cells are already healed, they are in a state of reduced inflammation and enhanced collagen production. In this way, the subjects are likely to have better skin health, lesser pain and overall better health. Our devices are designed to deliver and stimulate the tissue with optimal light for a variety of therapeutic purposes.
