Does LLLT cause a heating of the tissue?
Due to increased microcirculation there is usually an increase of 0.5~1 centigrade locally. The biological effects have nothing to do with the heat. Our patented taped-laser module plays a roll of laser beam reflection shield, makes more microcirculation. Therefore, an increase of 2~3 centigrade in the attached part is normal. Other GaAlAs lasers in the 300-500 mW or higher range will cause a noticeable heat sensation, particularly in hairy areas and on sensitive tissues such as lips.
