The biostimulative effects exerted by various low-energy lasers in the visible light have been used in medicine for treating a wide range of pathological conditions. Because clinical endpoints in phototherapy are initiated by a sequence of events at the molecular and cellular levels, the present overview summarizes recent results that might clarify the stimulatory effects of visible light on various tissues. It appears that light-induced reactive oxygen species and changes in Ca2+ homeostasis are of paramount importance in visible light–tissue interaction. Drug Dev. Res. 50:471–475, 2000.
