Direct answer

An Illinois med spa that offers neurotoxins, fillers, weight loss injections, or lasers is practicing medicine. The IDFPR and IDPH medspa memo (updated October 30, 2025) says medspas must be owned and operated by physicians, with some services allowed under full practice authority APRNs. Physicians delegate under 225 ILCS 60/54.2, and lasers follow 68 Ill. Adm. Code 1285.336. A lay founder owns the MSO, not the practice. Foundry forms that MSO-PC for $15,000 one-time and matches an Illinois-licensed friendly PC owner for $3,000/mo.

Illinois is one of the strictest corporate practice states. The ownership rules, the Berlin hospital exception, and the fee-splitting statute are on Illinois CPOM, and the CPOM 50-state guide compares Illinois with its neighbors. For the general aesthetics build, start at the med spa MSO-PC hub. General information only, not legal advice. Foundry is not a law firm.

Who may do what in an Illinois med spa

Service	Who may perform it	Illinois rule
Neurotoxins, fillers, weight loss injections	Physicians; full practice authority APRNs within scope; trained delegates of a physician	225 ILCS 60/54.2 delegation; unlicensed delegates need a licensed professional on site (IDFPR memo)
Ablative laser procedures	Physician, or a trained delegate with the physician on site	68 Ill. Adm. Code 1285.336
Non-ablative laser and IPL	Trained delegate after a physician exam and treatment plan	Physician on site or reachable by phone or electronic means; documented training
Non-ablative laser hair removal	Trained RN or LPN under a physician delegation protocol	Since Jan 1, 2025, the exam may be done by an APRN; physician must be reachable
Facials and superficial peels	Licensed estheticians	No work on living layers of skin (225 ILCS 410/3-1, 3A-1)

The IDFPR Statement on Prohibited Practices treats Botox, chemical peels other than superficial ones, collagen injections, microneedling, microblading, radio frequency treatments, and liposuction as the practice of medicine. An esthetician on your payroll cannot do those, even with a physician in the next room. Class 3b and Class 4 lasers also have to be registered with the Illinois Emergency Management Agency.

APRNs and the medical director question

Illinois APRNs who hold full practice authority under 225 ILCS 65/65-43 can examine, prescribe, and inject within scope. APRNs without it need a written collaborative agreement. Either way, the memo puts ownership of the medspa with physicians, so an APRN injector does not solve the ownership question, and a medical director title on a lay-owned LLC is not ownership either. Read physician PC owner vs medical director before you hire for the role.

Who owns the Illinois practice

Role	Where it sits	Illinois note
Physician owner	Owns the professional entity	Medical Corporation Act (805 ILCS 15), Professional Service Corporation Act (805 ILCS 10), or PLLC Act (805 ILCS 185); physicians only as shareholders, officers, and directors, with narrow exceptions
Entity registration	Filed with IDFPR	Professional entities register with IDFPR, and one entity offers one type of professional service, so cosmetology sits in a separate company
Injectors and laser staff	Employed or contracted by the PC	Licensed clinicians and trained delegates under written protocols
Founder and investors	Own the MSO	Lease, brand, booking, retail products, marketing
MSO fee	Written management services agreement	Fixed or cost-plus at fair market value; no split of professional fees

Treatment revenue belongs to the PC. A salon or retail company in the same building cannot use the word "medical" in its name (68 Ill. Adm. Code 1175.1305(b)), and physician advertising follows 225 ILCS 60/26. Run the MSA red-flag audit on CPOM compliance before you sign. Adding virtual consults?

Illinois med spa MSO-PC FAQ

Who can inject Botox in an Illinois med spa?

Physicians can prescribe and administer Botox and weight loss injections. Full practice authority APRNs can do so within scope under 225 ILCS 65/65-43, and a physician can delegate injections to trained staff under 225 ILCS 60/54.2. The IDFPR and IDPH medspa memo says an unlicensed delegate needs a licensed professional on site. Estheticians and cosmetologists cannot inject.

Does a physician have to be on site for lasers in Illinois?

For ablative laser procedures, yes. 68 Ill. Adm. Code 1285.336 requires on-site physician supervision when ablative work is delegated. For non-ablative procedures the physician may be on site or available by phone or other electronic means, and the delegate needs documented training.

Does Illinois still require a physician exam before laser hair removal?

Not in every case. Since January 1, 2025, a physician exam on site is not required before non-ablative laser hair removal if the facility follows a physician delegation protocol, an APRN does the exam, a trained RN or LPN performs the treatment, and the physician can be reached.

Can a lay founder own an Illinois med spa?

Not the medical side. The IDFPR memo says medspas must be owned and operated by physicians, with some services allowed under APRNs. A lay founder can own the MSO that runs the brand, lease, booking, and retail, and pay it a fixed fair-market-value fee. The clinical entity is a medical corporation, professional service corporation, or PLLC owned by Illinois-licensed physicians.

How much does Foundry charge for an Illinois med spa MSO-PC?
