Training & certification expected

No state-mandated injector training beyond licensure.

The license that lets you inject

MD/DO only; NP/PA/RN may not inject neurotoxins or fillers

If you’re an RN

No; RNs cannot inject neurotoxins or fillers in Massachusetts

Why the order still matters

Required; in-person exam mandatory before any treatment Training gets you the skill; a valid order or good-faith exam is what keeps the treatment lawful.

What to verify in Massachusetts

Ensure a licensed Massachusetts physician owns or has controlling interest in the practice; do not attempt to operate under a non-physician MSO structure.
