What is the best skin device for home use?

We all get older and there are a lot of different products out there in the markets to buy.
One that I have read about; ageLOC Edition Galvanic Spa System ™ II seems to be good. But one needs in addition to the device itself various ointments, drugs and all this makes me confused.
- A friend  recommended me to ageLOC Edition Galvanic Spa System machine, but I'm not sure because it is expensive.
