In Japan it seems that they love anything that “generates” ions. Ion generator gadgets are supposed to be improving the quality of the air that you breath by generation positive or negative ions. You can even select your preference in many of them! In my office we have two of them, the office ladies working with me love them, but when I ask them “What is an ion?” they look at me with a funny ignorance/who cares face.

For your face. You have to move it around your face everyday and it will improve your skin.
Ions only for men! WTF
