Laboratory Methods for Evaluating the Effect of Low Level Laser Therapy (LLLT) In Wound Healing
Special thanks goes to Kingpin from Regrowth for bringing this to our attention.
I’ve included the most important part of the study below but please click on link for more information.

“Light of a number of different wavelengths, specifically 660, 820, 870nm, at an energy density of 2.4J/cm2, has been shown to stimulate the ability of macrophages in vitro to release growth factors, which stimulate fibroblast proliferation; in contrast, light of 880nm wavelength was inhibitory (Smith, 1991). At 660nm the stimulatory effect of LLLT is dose dependent for exposure to energy densities of 2.4 - 7.2J/cm2, the upper end of the range being most effective and with 9.6J/cm2 proving to be less effective than 7.2J/cm2.”
