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!
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!
