CACI -microcurrent facial
Microcurrent facial aka electric facial uses extremely low-voltage electrical currents (hence 'micro' current) to mirror your own body's electrical currents. This retrains the underlying muscles in your face to return to the tightness they were years ago. THe CACI Ultimate is the leading microcurrent machine in the industry.
Microcurrent was invented in the 1960's to treat bell's palsy. It would actually lift the muscles in people with one side of their face drooping. That means it is proven and capable for cosmetic and beauty uses like lilfting your eyebrows or tightening your neck and cheek muscles.

Most people will see results immediately, but for best results, packages of 10 treatments are recommended.
