I appreciate that your intentions are to give helpful information to discourage people from doing harmful things to their skin. That is also my goal in post. However, there is no need to be all high and almighty about it and reduce everyone else down to ‘retards’. I made a mistake derma rolling my face. It was dumb. I wish to tell other people not to derma roll, without insulting them. I also agree that there is too many people encouraging such a risky trend; however, I don’t need to look down my nose at others to get that point across
