“Dose was also shown to have influence on the outcome of the treatment as on both cases, the use of 20 J/cm2 resulted on better effects on the healing process resulting on better organization and distribution of collagen fibers and influencing the numbers of myofibroblast”

“The present study indicates that the use of 685-nm laser light or polarized light with a dose of 20 J/cm2 resulted in increased collagen deposition and better organization on healing wounds, and that the number of myofibroblasts is increased when polarized light is used.”
