Microcurrent facials are like a gym workout for your face.
The muscles on the face start going south, just like everything else. We have to keep it fit. So, we use current to stimulate the muscle, starting low then increasing gradually until you have the firmness you would like.
It also stimulates collagen, so you'll have a fuller look as well. Collagen is the main protein the body has to build muscle. As we age, we lose collagen.
