Was skinny all my life, finally gained weight after sitting at home for almost two years and was able to pop out this blackhead on my chest. I used to be so skinny that I didn't have loose skin to squeeze it out!
I used a hydrocoiod bandaid on a pimple, and drianed a lot out, pretty sure the purple is just scar tissue / bruising. but now I'm having a bad blister reaction to the adhesive!
