How does Microcurrent technology compare to Laser light?
To a certain extent, micro current electric is a crude way of doing the same thing LED light does which is energy exchange at a cellular level. They don’t have the potential breadth of cellular effect that light imparts on cells. Microcurrent is an unsophisticated way of energy exchange and energy exchange dissipates in the form of heat. It works by micro changes and intracellular temperature levels that induce physiological effects.
If you impart electricity to a tissue it will travel preferentially through the path of least resistant. It will find nerves and it will travel through muscle because muscle contracts. It will not travel through skin or fat very well because these tissues are relatively resistant to heat. Muscle contraction and long term facial rejuvenation hasn’t been proven scientifically and the effects don’t last.
