Thanks for your question and posting pictures. Do not get upset. The good news is the birthmark is dark and you have lighter skin. That is a good combination for energy devices. Unfortunately, there isn't one device that will work on everyone for this. After a consultation in a medical setting, we would probably start with our highest success option of the PicoSure laser with either the FOCUS and / or Flat lens. Some physicians on this site have also suggested a tattoo laser. We could also try the PicoSure in tattoo mode for a test spot. None of these options should make it worse and more than likely one will work very well to minimize or even eliminate it. I hope this helps
