Complications of microneedling – what should I do?
Thank you for writing. Microneedling is new enough that complications are only recently being reported in medical journals and the lay press. A radiofrequency microneedling system is different from and more aggressive than a hand held simple roller microneedling system. In my opinion, for the present, I recommend avoiding the radiofrequency versions due to minimal data and a lack of standardized protocols.
In general, and I know this is a little counterintuitive, a fractionated CO2 laser or fractionated erbium (like Fraxel Restore 1550) will improve most types of depressed scars on the face. These two types of lasers have years of science and experience of use for improving scars. Please consult an expert in your area.
Hope this helps, Dr. I
