Thanks for sharing all this information. I am also having acne breakouts and I am well past the teen years. I will use something and it will seem to work but then it doesn't anymore. Also, I know some of it has to be hormonal because certain times of the month I break out and no matter what I was doing that worked, it no longer helps. In fact, I am dreading summer because of how bad it can be. I don't know if having blood work done, like a female hormone panel, would be helpful or not.
