What is the difference between the microcurrent and a laser?

Microcurrent provides electrons and in published studies increases ATP production in cells. Lasers provide photons. I am not aware of any research suggesting that laser treatment increases ATP production. Lasers oscillate at set frequencies and provide beneficial results but usually only provide one frequency at a time instead of the dual frequencies used in FSM treatment. Lasers provide whatever benefits they provide by some other method than frequency specific resonance and ATP enhancement.
