I know I have seen tons of forums about acne being caused by Paragard IUD, but mine is the opposite.
While I was in high school(age 16) I developed Cystic acne, I was placed on Accutane and within 6 months my face was clear. The scars came out but great thing is I had no Acne. That lasted 12 years. The Paragard was placed in me October 2012, oddly enough I had it removed October 2016. I developed copper Toxicity, it felt like poison running through my veins. My smell was off, my stomach was bloating daily, and much more. Within 1 month of having Paragard removed, my forehead broke out with little bumps everywhere. Then it moved down my face in sections. Currently my chin down jawline is the main zone of the cystic acne. It has made me self conscious completely. 
I tried ACV, baking soda, Charcoal bar, honey, em on and epsom salt. Even put spf containing zinc on the areas needed. Nothing has helped. I tried to take Zinc, but it gives extreme anxiety, hot flashes, and nausea.
i like to get advise from users that have similar if not exact experiences like me, since doctors do not understand. Nor do I want to Be card on hormone triggering medicine that could interrupt the progress I've made once removing paragard, mentally and physically
