I purchased this a few years ago. It's a facial device from Amin that combines Sonic, EMS, RF, Ion Cleansing, and Ion Introduction! It's convenient because it's all-in-one, compact, and easy to use. All functions have been confirmed to be working perfectly, with no issues. I'm selling it because I haven't had much time to use it lately. I've taken a lot of photos, so please check them for anything you're concerned about. Also, please feel free to ask if you have any questions! Thank you very much m(__)m Facial Beauty Device Beauty Equipment
