Can microcurrent do permanent damage around the eyes?

I recieved a facial at a doctors office and they suggested a microcurrent add on. Unfortunately I agreed to the treatment and it immediately left my eyes looking hollow and tired. This was about 8 months ago and the effect persists. I'm not sure what is contributing to the older, tired look that I have but I am wondering if the micro current damaged the skin or underlying tissue. Is this possible? The doctors office has no explanation. They just say it "wasn't supposed to happen". Thank you.
