@53de482a What kind of skincare?   The only reports on microcurrent I could find on pubMed was for wound healing.

#Microcurrent is real and can be used for pain, nerve stimulation. They get blood flowing in an area. Not sure (every) facial stimulators can build up muscle to reduce sagging. I was considering them and may yet again. 

But I recently forked out cash for omnilux so it will have to wait. I see improvement in texture with #redlighttherapy. I'm pretty sold on those. I've used it for back pain too.

I recently found out about PAO exerciser on Dr Dray. $125 Hmm.

I don't know anything about skincare, but the "sciencey" side of me tends to believe "microcurrent" as a skin treatment is nonsense.

Healthy skin is all about elasticity & bloodflow. Running current through the skin would harm BOTH those things.

Ever see a hotdog hooked up to a car battery? 😆 😉
