Scope check
Who may lawfully perform this, in this state?
Checked against the rule the state actually wrote down — quoted, cited, and linked at source. This compares a procedure against a published limit; it is not a judgement about what a treatment does to skin, and it is not legal advice.
Our scope corpus holds rules read at source for 51 states across 9 service categories. Coverage is uneven and we show you which you are in on every answer. Where we have not read a rule we say so — we never treat our silence as the state's permission.
Missouri · Injectable (neuromodulator, dermal filler) · Rule on record
We have read and cited this state's own rule for injectable (neuromodulator, dermal filler). The verdict below rests on that text, linked at source so you can verify it.
Injectable (neuromodulator, dermal filler) is outside Esthetician scope in MO.
Missouri enumerates the Class E esthetician occupation as a CLOSED LIST of manual and apparatus-based skin practices — massaging, cleansing, stimulating, manipulating, exercising, beautifying and hair removal by means other than an electric needle — with no injection among them. Injecting a prescription drug is treating the sick within the Medical Practice Act, which makes it unlawful for a person who is not a registered physician. Note the statute also caps preparations used by a Class E licensee at ten percent phenol; that is a limit on the preparation, and this corpus does not read it as authority to perform a phenol peel.

MedSpaRadar is regulatory monitoring and reference: it summarizes public laws, regulations and agency actions and links each to its source. It is not legal, medical, or compliance advice, and using it creates no attorney-client relationship. A summary can lag its source or leave out detail, and monitoring itself can be interrupted — so an absence of alerts means nothing reached you, not that nothing happened. Read the cited source, check its effective date, and confirm any change to your operations or clinical practice with qualified health-law counsel and your medical director.
Where the corpus is deep, and where it isn’t
Read this before you rely on a quiet answer. A category with few states behind it is a category where we will more often tell you we don’t know — which is the correct answer, and not the same as a green light.
| Procedure | States with a rule on record |
|---|---|
| Injectable (neuromodulator, dermal filler) | 46 |
| Energy device (laser, IPL, RF, plasma, ultrasound) | 39 |

Every rule behind these answers is read at an official source and cited. The wider cited corpus — supervision, good-faith exams, ownership and CPOM, advertising — lives on the state pages, and how we decide what to publish is written down in the methodology.
