There has been a fair amount of work done with both microcurrent electrical stimulation and magnetic field stimulation on wound healing. Microcurrents, on the order of 1mA-3mA (milli Amps) have been shown to decrease healing time of open wounds by significant amounts. Typically the wounds were treated with alternating polarity (+/-) for one hour/day for weeks to months. So I think there is great potential for the use of electrical stimulation in wound healing.
As far has for face lifting there are no scientific studies. Companies have taken this wound healing data and tried to equate it to normal skin. This is a stretch at best. Most of the "data" out there "regarding microcurrent facelifts" suggest skin changes after 20 days. That a one hour treatment every day for 3 weeks. Then maybe it will help.
Don't waste your money on unproven therapies. Stick to what has been proven time and again.
