Training & certification expected
No state-mandated injector training beyond licensure; physician training and credentialing expected
The license that lets you inject
MD/DO only; NP/PA and RN may not inject neurotoxins/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 medspa; non-physician ownership is not permitted for injection-based practices.
