Help me out?

I used to have problem area's concerning blemishes. back, neck, around the hair line and on the chin. I started thinking one day that there must be a reason for these blemishes to keep coming back in the same spot, so i had a look at what i was doing everyday that would cause this. I took a look at how i showered, what i did first, next, last etc, and thought this might be the root of my problem. The bigger problem is that this change of routine coincided with me starting to walk/jog outside in the sun, so im left baffled, if it was the exercise, sunshine or change of routine that fixed my skin. I am unwilling to stop doing each one to rule them out so im wondering if anyone else, suffering from the same skin problems will follow my shower routine and see if it makes a difference in their skin? If you would like to do this for me, ill repost in a week or so and you can answer back to see if it made a difference. Im just really curious to know if it really matters that much how you wash
