I've asked several dermatologists and aestheticians about this, and they've all been opposed to it. I'd personally agree, though I do use it from time to time. I definitely say see a derm if possible, but if you must use it, just be sure the tool is clean and your face is cleansed and dried prior to use (if it's oily or wet, the tool will slip around and cause more damage). I follow it with at soothing tonor (even just witch hazel works). Good luck!
