Illinois med spa ownership rules: who can own a med spa in Illinois
In Illinois, a med spa must be owned and operated by physicians, or for some services by advanced practice registered nurses (APRNs) with full practice authority. That is the position of the Illinois Department of Financial and Professional Regulation (IDFPR) and Department of Public Health in their joint med spa memo, updated October 30, 2025. A person who is not a physician or APRN cannot be a shareholder, member, officer, director or manager of the entity, and med spas organized as professional entities must register with IDFPR.
- IDFPR: med spas must be owned and operated by physicians, and for some services by APRNs, because the services are medical.
- No lay owners, officers or managers in the professional entity, with limited exceptions for physician entities.
- Physicians may use a medical corporation, professional service corporation or PLLC; APRNs may use only a PSC or PLLC. All must register with IDFPR as well as file with the Secretary of State.
- A medical entity cannot also practice cosmetology or esthetics, and a salon registration cannot be used to run a med spa.
- Light-based procedures that disrupt the epidermal surface are the practice of medicine; delegated ablative work needs on-site physician supervision.
- Every practice welcome — retainers from $499/mo, Goals-Driven engagements, Performance-Linked Payout Models available.

“They were able to get all my ideas and work with me over a period of three to four months and create this amazing website. It's super customized, very modern, and it incorporates all the elements that I had wanted — the patient portal, nice pictures, a very interactive website, patient reviews. I would highly recommend their company to anyone who wants to make an excellent website.”
Who can own a med spa in Illinois
Short answer: physicians, and for some services APRNs. Illinois regulators have said so in writing, which makes Illinois one of the clearer states.
The IDFPR and IDPH memo on medical spa services lays out the ownership rules directly. The Medical Practice Act and the Nurse Practice Act require med spas to be owned and operated by physicians, and for some services by APRNs, because the services provided are medical services. From there:
- Physician entities: only physicians may organize under the Medical Corporation Act (805 ILCS 15). Physicians may also use the Professional Service Corporation Act (805 ILCS 10) or the Professional Limited Liability Company Act (805 ILCS 185). A physician-operated entity may only have physicians as shareholders, members, officers, directors or managers, with some limited exceptions.
- APRN entities: APRNs may organize only as a professional service corporation or PLLC, and the entity may only have APRNs as owners, officers, directors or managers.
- No lay participants in the entity: a person who is not a physician or APRN cannot be a shareholder or member, officer, director or manager.
- Unincorporated med spas: a sole proprietorship or partnership must be owned and operated by physicians or APRNs.
One more structural rule surprises founders. Professional entities may perform only one type of professional service plus listed related services, and none of those related services would let the same entity practice both medicine and cosmetology or esthetics. A med spa that also wants a salon side needs to keep those businesses separate, and a salon registration cannot be used to operate a med spa.
What counts as medicine in an Illinois med spa
Short answer: injections, prescription drugs, procedures that affect the living layers of skin, and laser or light-based treatments that disrupt the epidermis.
- Physicians may operate a med spa, perform cosmetic procedures that affect the living layers of skin, prescribe and administer drugs including Botox and weight-loss injections, and supervise and delegate those procedures (225 ILCS 60/54.2).
- Delegation to unlicensed staff is allowed in an office setting within a physician-patient relationship, only if a licensed health care professional is on site to assist.
- Estheticians and cosmetologists may not affect the living layers of the skin. IDFPR lists Botox, chemical peels (except superficial peels), collagen injections, microblading, microneedling and radio frequency as the practice of medicine.
- Lasers and light devices: under 68 Ill. Adm. Code 1285.336, light-emitting devices used for procedures that disrupt the epidermal surface, ablative or non-ablative, are the practice of medicine. Ablative procedures may be delegated to trained LPNs, RNs, full practice authority APRNs or others with on-site physician supervision. Non-ablative procedures may be delegated with on-site supervision or with the physician available by phone or electronic means.
- Laser hair removal exams: since January 1, 2025, an on-site physician exam is not required before a non-ablative laser procedure if the facility follows a physician delegation protocol, an APRN performs the exam, a trained RN or LPN performs the procedure, and a physician is available remotely.
The memo also reminds med spas that IDPH treats them as health care facilities for infection prevention, and that all staff are designated reporters of unusual infections and outbreaks to the local health department. For supervision duties, see our med spa medical director requirements guide.
Illinois med spa registration checklist
- Confirm ownership eligibility: physicians, or APRNs for the services an APRN entity may provide. No lay shareholders, officers or managers.
- Pick the entity: medical corporation (physicians only), professional service corporation or PLLC.
- File articles with the Illinois Secretary of State and register the entity with IDFPR as a medical corporation, PSC or PLLC.
- Keep salon services separate. If you also offer esthetics, that business needs its own salon registration, and it may not use "medical" in its name.
- Write delegation protocols for injectables and lasers that match 225 ILCS 60/54.2 and 68 Ill. Adm. Code 1285.336, including documented device training for every operator.
- Infection prevention program following CDC outpatient guidance, with a trained person responsible, and a plan for reporting to the local health department.
- Drug sourcing and controlled substances: authorized distributors only; an Illinois controlled substance license and DEA registration where required.
- Privacy: HIPAA policies and Business Associate Agreements with vendors that handle patient data.
What ownership means for Illinois med spa marketing
Short answer: every Illinois med spa is bound by the Medical Practice Act's advertising section, and staff roles in your marketing must match the law.
- Advertising rules: 225 ILCS 60/26 applies to all med spas. Our Illinois Medical Practice Act advertising rules guide covers it in detail.
- Esthetician roles: don't present delegated medical procedures as "esthetic services", and don't describe an esthetician performing delegated work as practicing esthetics.
- Business names: a salon may not use "medical" or similar terms. Make sure the brand on your Google Business Profile matches the right registered entity.
- Before-and-after content and claims: see our before-and-after photo guide and off-label injectable advertising guide.

What we found when we studied 555 US med spas on Google
Patients praise the care almost without exception. The one area where complaints outnumber praise is booking and communication, and that is where most med spas can win.

Common Illinois med spa mistakes
- A lay investor on the cap table or as manager of the professional entity.
- Running a med spa under a salon registration. IDFPR says a salon registration cannot be used to operate a med spa.
- One entity for medicine and esthetics. The professional entity acts do not permit both.
- Skipping IDFPR registration after filing with the Secretary of State.
- Estheticians microneedling or doing medium-depth peels as esthetic services.
- No infection prevention program. IDPH expects one in every med spa.

Common questions
Can a non-physician own a med spa in Illinois?
Not unless they are an APRN, and then only for some services. IDFPR's med spa memo says a person who is not a physician or an APRN cannot be a shareholder or member, officer, director or manager of a med spa entity. A med spa that is a sole proprietorship or partnership must be owned and operated by physicians or APRNs.
Can a nurse practitioner own a med spa in Illinois?
IDFPR says that for some services, a med spa can be owned and operated by an APRN. APRNs may organize only under the Professional Service Corporation Act or the Professional Limited Liability Company Act, and an APRN entity may only have APRNs as owners and officers. APRNs with full practice authority can practice without a written collaborative agreement in settings consistent with their national certification, but their authority does not include operative surgery.
Do Illinois med spas need to register with the state?
Yes, if organized as a professional limited liability company, professional service corporation or medical corporation. These med spas must register with IDFPR in addition to filing articles with the Illinois Secretary of State.
Can estheticians work in an Illinois med spa?
Yes, as employees, but an esthetician performing a procedure delegated by a physician may not hold themselves out as practicing esthetics while doing it. Cosmetologists and estheticians may not use techniques intended to affect the living layers of the skin, and IDFPR lists Botox, chemical peels other than superficial peels, microneedling, microblading and radio frequency among services that are the practice of medicine.
Who can perform laser hair removal in Illinois?
Laser procedures are the practice of medicine in Illinois. A physician may delegate non-ablative procedures such as laser hair removal to trained nurses, full practice authority APRNs or other persons, with on-site supervision or with the physician available by telephone or electronic means. Since January 1, 2025, an on-site physician exam before a non-ablative laser procedure is not required if the facility follows a physician delegation protocol, an APRN performs the exam, a trained RN or LPN performs the procedure and a physician is available remotely.
What advertising rules apply to Illinois med spas?
IDFPR says all med spas are subject to the Medical Practice Act, including its advertising section (225 ILCS 60/26). Salons and shops also may not use "medical" or similar terms in their business names.
A note on this guide: it explains marketing practice, not legal advice. Rules on privacy, advertising and insurance change and vary by state, so confirm anything compliance-related with your own counsel.
