Who can inject Botox in Illinois?

Last checked October 25, 2026 against the sources listed below. Information, not legal advice: confirm with the board before you treat patients.

In Illinois, injecting Botox is the practice of medicine. Physicians can inject, and so can physician assistants and nurse practitioners within their collaborative agreement (or, for nurse practitioners with full practice authority, within their national certification). Registered nurses can inject under a physician's supervision and delegation, after the physician has examined the patient. Estheticians cannot inject under their license, and the state's list of who may inject Botox does not include medical assistants.

Who can inject in Illinois: role by role

Role	Botox (neurotoxins)	Dermal fillers	Conditions
Physician (MD/DO)	Yes	Yes	Within the physician's own scope. A physician may supervise and delegate these procedures. Each person treated must be the physician's patient.
Physician assistant	Yes, with conditions	Yes, with conditions	Must fit the PA's written collaborative agreement with a physician, which lists the categories of care and procedures the PA provides. The physician does not have to be on site.
Nurse practitioner (APRN)	Yes, with conditions	Yes, with conditions	Without full practice authority: must fit a written collaborative agreement with a physician. With full practice authority: must fit the APRN's national certification. Full practice authority requires 4,000 clinical hours and 250 hours of continuing education or training after national certification.
Registered nurse	Yes, with conditions	Yes, with conditions	Under a physician's supervision and delegation. The person treated must be the physician's patient, and the physician must examine the patient and set the course of treatment. For fillers, IDFPR names "collagen injections" and the medspa memo applies the same physician delegation rule. No Illinois agency says an NP or PA can stand in for the physician when an RN injects.
LPN	Not addressed	Not addressed	IDPH says "nurses" may inject under a physician's supervision but does not separate RNs from LPNs. A physician may delegate tasks to an LPN within the LPN's own licensing law, and IDFPR names LPNs as possible delegates for lasers. No Illinois source names LPNs for injectables. Confirm with IDFPR before injecting.
Medical assistant	No	Not addressed	IDPH says Botox may only be injected by certain licensed professionals, and medical assistants are not on its list. The Medical Practice Act does let a physician delegate tasks to trained unlicensed staff in an office with a licensed professional on site, and the medspa memo mentions trained "laypersons." No agency has said that covers injections. No board statement found on medical assistants and fillers; the IDPH list of who may perform procedures that affect the living layers of the skin names only licensed roles.
Esthetician	No	No	Not under an esthetics or cosmetology license. Estheticians may not use any practice that affects the living layers of the skin, and IDFPR lists Botox and collagen injections as the practice of medicine. A medspa may employ an esthetician, but during a physician-delegated procedure that person may not act or present as an esthetician. Whether an unlicensed delegate may inject at all is the same open question as for medical assistants.

The patient exam before treatment

IDFPR says that when a physician delegates a procedure such as Botox or collagen injections, the person treated must be the physician's patient. The physician must examine the patient and decide whether the treatment is appropriate and what the course of treatment is. The person who receives the delegation then carries out the treatment as instructed.

Nurse practitioners and PAs can examine their own patients within their own authority: a full practice authority APRN under national certification, and other APRNs and PAs under their collaborative agreements. The guidance on delegated procedures is written around the physician. It does not say whether an exam by a nurse practitioner or PA is enough when an RN injects.

No Illinois rule says whether this exam must be in person or can be done by telehealth for injectables. A change effective January 1, 2025 lets an APRN do the exam before a non-ablative laser procedure, but that change covers lasers only.

Supervision and delegation

Registered nurses inject "under the supervision of a physician," according to the Illinois Department of Public Health. The rules do not say whether the physician must be on site for injectables.
NP or PA instead of a physician. No Illinois agency says an RN may inject Botox or fillers on an NP's or PA's order alone. Full practice authority APRNs may by law delegate selected nursing interventions to RNs, LPNs and other staff. But the state's medspa memo and IDFPR's delegation statement are both written around the physician. Get written confirmation from IDFPR or counsel before running an RN team under an NP or PA alone.
Physician delegation is set out in the Medical Practice Act (225 ILCS 60/54.2). A physician may delegate patient care tasks to RNs, LPNs and other licensed people within their own licensing law. The task must fall within the physician's own scope, training and experience, and within a physician-patient relationship. Delegation can be oral, written, electronic, or by standing orders or protocols.
Unlicensed staff can receive delegated tasks only in an office or practice setting, within a physician-patient relationship, with a licensed health professional on site. IDPH separately says Botox may only be injected by certain licensed professionals. No agency has reconciled the two, so the narrower IDPH statement is the safer reading.
An RN cannot hand off Botox injections to unlicensed staff at a medspa. Under 225 ILCS 65/50-75, an RN may delegate medication administration to unlicensed staff only in community or home care settings, and only for oral, subcutaneous, topical or transdermal routes.
Nurse practitioners and PAs with collaborative agreements do not need the physician physically present. Consultation can be in person or by phone or electronic means.

Med spa ownership and the medical director

Illinois follows the corporate practice of medicine doctrine. The Illinois Supreme Court has said the ban on corporate employment of physicians is "entirely appropriate" for a general corporation with no license to offer medical services, while licensed hospitals are an exception.

IDFPR and IDPH say medspas must be owned and operated by physicians, and for some services by APRNs. A person who is not a physician or APRN cannot be a shareholder, member, officer, director or manager of the practice entity. Only physicians may form a medical corporation. Physicians and APRNs may form a professional service corporation or professional LLC, which must register with IDFPR.

A medspa cannot practice medicine and esthetics in the same entity, and a salon registration cannot be used to operate a medspa. Salons may not use "medical" in their business name.

No Illinois rule found requires a formal "medical director" title. Instead, medical procedures at a medspa must be done by a physician or by staff the physician delegates to, trains and supervises.

Training and certification

No Illinois rule found requires a state injector certificate or a set number of training hours for Botox or fillers. Your nursing, APRN or PA license is the credential. The state does expect anyone performing a delegated procedure to be properly trained and supervised, and the delegated task must be within the delegating physician's own training and experience. Documented training rules exist for lasers (68 Ill. Adm. Code 1285.336), not injectables.

Recent changes

April 2024: After a cluster of botulism-like illness, IDPH published who may inject botulinum toxin in Illinois. Both hospitalized patients had been injected by a licensed nurse working outside her authority.
January 1, 2025: House Bill 4357 took effect. It changed the exam rule for non-ablative laser procedures so an APRN can do the exam. It does not cover injectables.
October 30, 2025: IDFPR and IDPH updated their joint medspa memo covering ownership, delegation, esthetician limits and infection control.
April 6, 2026: IDFPR's current Statement on Prohibited Practices for cosmetologists and estheticians is dated this day. It lists Botox and collagen injections as the practice of medicine and states the physician exam requirement.

FAQ

Can an RN inject Botox in Illinois without a doctor on site?

Illinois says RNs inject under a physician's supervision, after the physician has examined the patient, but it does not say the physician must be in the room. Your practice's delegation protocol should spell out how the physician is available.

Can an RN inject under a nurse practitioner instead of a physician?

The state has not said so. IDPH and IDFPR describe RN injections under physician supervision and a physician exam. Full practice authority APRNs can delegate some nursing tasks by law, but no agency has applied that to cosmetic injections.

Can a nurse practitioner open a med spa in Illinois?

Yes, in some cases. The state says medspas must be owned by physicians, and for some services by APRNs, through a professional service corporation or professional LLC registered with IDFPR. People who are not physicians or APRNs cannot be owners, officers or managers.

Can a medical assistant inject Botox in Illinois?

Not according to IDPH, which says only certain licensed professionals may inject botulinum toxin and does not list medical assistants. The Medical Practice Act has a general rule for delegating tasks to trained unlicensed staff, but no Illinois agency has said it covers injections.

Can an esthetician do Botox or fillers in Illinois?

Not under an esthetics license. Estheticians may not affect the living layers of the skin, and IDFPR lists Botox and collagen injections as the practice of medicine.
