Botulinum toxin is a prescription drug, so the person who injects it is either licensed to administer prescription drugs or has been lawfully delegated the act by someone who is. Every state accepts a physician, an NP within the state’s practice model, and a PA under supervision. Nearly every state accepts an RN on a valid order after a good faith exam. Below that line the answers diverge sharply: LPNs in some states, medical assistants in a few, estheticians in none we have found. And the rule for filler is not always the rule for neurotoxin.
The two questions the license does not answer
First, who evaluated the patient. The good faith exam is a diagnosing-and-prescribing act reserved to a physician, NP or PA, and it comes before the injection in every state. The injector’s license does not change that. Second, who is supervising. Several states specify where the supervising physician must be, how many delegates they may carry and what must be posted on the wall.
State by state
| State | Physician, NP, PA | RN | LPN | Medical assistant | Esthetician | Notable rule | Authority |
|---|---|---|---|---|---|---|---|
| Louisiana | Yes | Neurotoxin yes, on order, with a physician or NP physically present; dermal filler expressly prohibited | Not addressed as permitted | Not addressed as permitted | No | Filler and neurotoxin split by license | LSBN Declaratory Statement |
| Washington | Yes | Yes, properly trained, under delegation | Yes, properly trained, under delegation | Not within WAC 246-919-606 | No | Physician may sponsor no more than three PAs for cosmetic procedures; delegate may not further delegate | WAC 246-919-606 |
| California | Yes | Yes, on physician order after an appropriate prior examination | Injections generally within LVN scope on order; cosmetic practice constrained by Board guidance | No: the Medical Board states medical assistants may not inject collagen, and their injection routes are limited to intradermal, subcutaneous and intramuscular after verification | No | Board FAQ answers the MA question directly | MBC FAQ; B&P 2069 |
| Florida | Yes | Yes, under supervision, on order | Within LPN scope on order | Statute permits nonintravenous injections under direct physician supervision; no cosmetic carve-out | No | Direct supervision means the physician is responsible for each act | Fla. Stat. 458.3485 |
| Texas | Yes | Yes, under delegation | Yes, under delegation | Delegation to qualified, properly trained persons is permitted under the Board’s rules, subject to the written order and supervision requirements | No | Delegating physician’s name and license number posted in every treatment room; every person performing a delegated act wears identification showing credentials | 22 TAC 169.25 to 169.29 |
| Colorado | Yes | Yes, through the Nurse Practice Act | Through the Nurse Practice Act | Delegation of medical-aesthetic services to unlicensed individuals is permitted, with disclosures | With disclosures, as an unlicensed delegate | HB25-1024: on-site sign, website statement and written consent where a physician or APRN delegates to a non-licensed person, effective 6 August 2025 | HB25-1024; Colorado Medical Board delegation rules |
| Pennsylvania | Yes | Yes, under delegation, after a good faith exam by a physician, CRNP or PA | Under delegation | Not addressed as permitted | No | Sequence rule: exam first, by a prescriber, then RN injection | 49 Pa. Code |
| New Mexico | Yes | Yes, on order | Under delegation | Not addressed as permitted | No | Order first; NP full practice | NMSA 1978 ch. 61 |
| Maryland | Yes | Yes, under COMAR 10.32.09 delegation | Under delegation | Under delegation where the rule permits, with training and supervision | No | Delegation of cosmetic procedures and devices governed by a dedicated regulation | COMAR 10.32.09 |
| Ohio | Yes | Yes | Yes | Not for light-based devices | No | No delegation of light-based devices for ablative procedures; on-site supervision in the same suite; no more than two RN or LPN delegates at once | OAC 4731-18 |
Where a cell says “not addressed as permitted,” the state’s rule names the licenses it allows and does not name that one; an operator relying on silence is relying on the argument that an unlicensed person may perform a medical act without delegation authority, which no board accepts.
Estheticians: the answer does not change by state
An esthetician’s license covers the skin’s surface. Injecting a prescription drug is the practice of medicine or nursing. The only route by which an esthetician could lawfully inject is as an unlicensed delegate in a state that permits delegation to unlicensed persons, which is how Colorado’s disclosure law and Texas’s delegation rules operate. In those states the esthetician license is irrelevant; the person is an unlicensed delegate with the training, supervision and disclosure obligations that attach to that status. In every other state on the table the answer is no.
Louisiana’s split is the one to remember
Louisiana permits an RN to inject FDA-approved neurotoxins on a prescriber’s order with a physician or NP physically present, and expressly prohibits the same RN from injecting dermal fillers. A booking system that treats “injectables” as one category will route a filler appointment to an RN column in Louisiana and produce a violation without anyone noticing. Split the menu by license before you split it by price.
Colorado’s answer is “yes, if you tell them”
Colorado did not ban delegating medical-aesthetic services to unlicensed people. It required disclosure: an on-site sign, a website and advertising statement, and written informed consent, effective 6 August 2025. The legal responsibility stays with the delegating physician or APRN, and patient selection, the protocol and complications response remain theirs. Delegation moves the performance of a task; it never moves the responsibility.
Texas puts names on the wall
Texas permits broad delegation, and pairs it with identification: the delegating physician’s name and Texas license number posted in every public area and treatment room, and every person performing a delegated act wearing identification that shows their credentials. A patient in a Texas treatment room can read who is responsible and what license the injector holds. That is the trade the state made for permissive delegation.
What this means for you
Build the injector roster from the state’s list, not from the industry’s habit. Confirm the evaluation is done by a physician, NP or PA before every treatment, whoever injects. Split neurotoxin and filler in the booking system wherever the state splits them. In Washington, count PAs against the three-per-physician cap. In Colorado, put up the sign and the website statement and collect the consent. In Texas, print the posting and issue the name tags. In Louisiana, keep a physician or NP physically on the premises whenever an RN is injecting. And in every state, treat “the esthetician does our Botox” as a sentence a board will read back to you. See how injectables are structured, the Pennsylvania sequence rule, New Mexico’s order rule and how good faith exams work.

Frequently asked questions
Can an esthetician inject Botox?
Not under an esthetician license in any state on this table. An esthetician’s scope is the skin’s surface. In states that permit delegation of medical-aesthetic services to unlicensed persons, such as Colorado with its disclosure requirements and Texas under its delegation rules, an esthetician may act only as an unlicensed delegate with the training, supervision and disclosure obligations that status carries.
Can an LPN inject Botox?
In some states, under delegation. Washington’s WAC 246-919-606 names properly trained LPNs as permitted delegates for nonsurgical cosmetic procedures. Texas permits delegation to qualified, properly trained persons. Other states name only RNs and above. Check the state’s delegation rule for the license, not the general nurse practice act.
Can a medical assistant inject Botox?
California’s Medical Board says medical assistants may not inject collagen and limits their injections to intradermal, subcutaneous and intramuscular routes after verification, under Business and Professions Code 2069. Florida’s 458.3485 permits nonintravenous injections under direct physician supervision without a cosmetic carve-out. Colorado and Texas permit delegation to unlicensed persons with disclosure and identification requirements.
Can a registered nurse inject Botox without a doctor present?
It depends on the state. Louisiana requires a physician or NP physically present on the premises while an RN performs cosmetic procedures. Texas requires the delegating physician, PA or APRN to be present or immediately available. Other states require a valid order after a good faith exam by a prescriber but not physical presence. In every state the RN injects on an order and does not perform the evaluation.
Can a nurse practitioner inject Botox independently?
In full-practice states such as Arizona and New Mexico, yes, within the NP’s prepared scope. In delegation and collaboration states the NP practices under a protocol or collaborative agreement with a physician, and the injecting is lawful within that framework. The NP may also perform the good faith exam, which an RN may not.
