Step one: Wash your face and neck and dry with a clean towel.
Step two: Clean your derma-roller by submersing it in standard drugstore rubbing alcohol.
Step three: Divide your face into four sections: the left and right sides of the forehead, the cheeks and the chin.
Step four: Working one section at a time, gently apply pressure while rolling the tool horizontally, vertically, and then diagonally, about 3 to 4 times at-most. Avoid delicate skin like the eyes and nose, only rolling over areas that are flat surfaces.
Step five: Clean your device by spritzing it with rubbing alcohol and letting it air dry (completely). Store in clean case.
Step six: Follow up with a serum, like vitamin C, to speed up recovery time.
Step seven: Avoid wearing make-up (unless mineral) for several days following the procedure.
As a suggestion, wait a week or more (depending on your reaction) before repeating. Users have experienced everything from allergic reactions to pain, redness, bleeding, and peeling. Your skin can also become inflamed if not performed correctly. So clean your tools!
