One thing to add to my post about my treatments: it sounds strange, but I recently changed my PC mouse. Looking back in my email purchase history, I think I bought the mouse at June 2011. I become aware of the skin problem at I think around March 2012, but it wasn’t often and just small (and thought it was acne and ignored it), so I likely had it before I noticed it. Because I liked the mouse (it’s a silent noise mouse), I later replaced it by two others of the same type (because the buttons weren’t working as good as they used to be). Recently, I found out that a lot of my PC system crashes were due to this mouse. The mouse was also giving me electric shocks recently, probably also due to the lower humidity and a bad electric design of the mouse. I have replaced it with a different mouse product at (I think) 5 December 2015, and haven’t seen those system crashes since then. Probably has nothing to do with my skin, but because it may effect my body (by maybe putting my constantly under electric charge while using the mouse, without noticing it), I wanted to add this here.
