This is a very important question! To start, who can perform the treatment varies by state laws. For instance, in Connecticut, microneedling is defined as a medical treatment (since needles puncture the skin) and only NPs, PAs, DOs, and MDs can perform this service. So find out the laws in your state regarding who can perform microneedling.
Thanks for your question. Microneedling should be physician supervised, but can be delegated to a subordinate. The rules vary by state. Microneedling should only be performed in a medical setting. The needles open your skin barrier and make you susceptible to infection without proper care. Best of luck.
