Here's some tips I have for dermarolling: test rolling on your hand to see if you're allergic, use Vitamin C serum and non-comedogenic moisturizer, DO NOT roll on active acne (this will spread bacteria and make you break out more), pick up the dermaroller off the skin in between strokes, sanitize the dermaroller before and after use (I soak it in rubbing alcohol and store it in the clear case it comes with), try to avoid wearing makeup after dermarolling(don't want makeup stuck deep down in the skin), and lastly, do not overdo it--depending on length of the needle, you'll need variant amounts of time between each session so the skin can heal, because remember you are puncturing holes into your face. I would definitely do some considerate research on dermarolling before starting.
