Washington Med Spa Regulations
Washington has no med-spa-specific statute; cosmetic injections and laser (LLRP) treatments are the practice of medicine under RCW 18.71 and are governed by Medical Commission rules (WAC 246-919-605/606) that let a responsible MD/DO delegate to trained PAs, RNs and LPNs, while ARNPs practice and prescribe fully independently and non-physicians may own a med spa so long as clinical control stays with licensed providers.

Who can inject Botox and dermal fillers in Washington?
Cosmetic injection of medication or substances is the practice of medicine in Washington. MDs and DOs may inject, ARNPs (nurse practitioners) may prescribe and inject independently, PAs may inject under their Medical-Commission-approved practice agreement, and a physician may delegate the injection to a properly trained registered nurse or licensed practical nurse under WAC 246-919-606. RNs must have an order/prescription from an authorized prescriber and be delegated the task; they cannot self-prescribe the injectable.

Does Washington require a good-faith exam before treatment?
Before authorizing any nonsurgical cosmetic procedure, the physician must take a patient history, perform an appropriate physical examination, make an appropriate diagnosis, recommend treatment, and obtain informed consent (WAC 246-919-606). The parallel laser rule (WAC 246-919-605) imposes the same pre-treatment history/exam/diagnosis/consent duties. The cosmetic rule does not expressly authorize a telehealth exam; Washington's general telemedicine framework permits establishing a provider-patient relationship remotely, but the rule text calls for a physical examination, so a purely remote good-faith exam for injectables is not clearly sanctioned.

Does a med spa in Washington need a medical director?
Washington has no statute that requires a titled 'medical director' for a med spa. However, whenever a med spa offers delegated medical cosmetic procedures (injectables or laser) performed by RNs/LPNs or PAs, a delegating/supervising MD or DO must authorize treatment and remains ultimately responsible for patient safety under WAC 246-919-606 and 246-919-605, and DOH guidance describes a medical director's role in ensuring each person practices within scope. The exception is an ARNP-run practice: because ARNPs are independent prescribers, a physician medical director is not legally required where the NP performs and prescribes the treatments.

Can a non-physician own a med spa in Washington?
Washington does not impose physician-only ownership on med spas or clinics. Under the Professional Service Corporation Act, physicians (RCW 18.71), physician assistants (RCW 18.71A), and advanced registered nurse practitioners (RCW 18.79) are each independently listed among the licensed health professionals who may organize and hold shares in a professional service corporation that renders health care services (RCW 18.100.050). Physician assistants are further and explicitly authorized to own their own practice or clinic under RCW 18.71A.120(8), which states outright that 'nothing in this section shall be construed as prohibiting physician assistants from owning their own practice or clinic.' This reflects ownership flexibility among licensed independent providers (physicians, ARNPs, and PAs) rather than a physician-only rule. It does not establish that unrestricted lay/non-clinician ownership of the clinical practice is settled: Washington DOH guidance to med spa operators cautions that any ownership structure must still navigate prohibitions on fee-splitting, rebating, and the corporate practice of medicine, and that authority over diagnosis, treatment, and prescribing must remain with the licensed provider regardless of who holds the business entity.

A direct, unequivocal statutory statement that a non-physician (PA) may own a clinic., WA DOH -- Med spa/esthetic services guidance. Confirmed via fetch: supports only the caution portion of the prose -- warns that ownership arrangements raise fee-splitting, rebating, and corporate-practice-of-medicine issues, and recommends attorney review; it does not itself state who may or may not own a med spa.
What supervision does Washington require for med-spa procedures?
Supervision intensity depends on the procedure and product. For FDA-approved medications used for approved purposes, the delegating physician need not be on-site but must be reachable by phone and able to respond within 30 minutes to treat complications; for unapproved medications or off-label/unapproved uses, the physician must be on-site for the entire procedure (WAC 246-919-606). For laser/LLRP treatments, the physician must be on the immediate premises during the patient's initial treatment, and for established patients on a treatment plan a backup physician must be reachable by phone and able to see the patient within 60 minutes (WAC 246-919-605). ARNPs require no supervision; PAs work under a practice agreement.

What can an esthetician legally do in Washington?
Estheticians and master estheticians (licensed under RCW 18.16) may perform cosmetic skin-care services independently, but they may not inject and may not use FDA prescription devices on their own authority. Per DOH guidance, if an esthetician uses a device the FDA has designated a prescription device — such as a laser or light-based device — on a person's skin, the esthetician may use it only under the supervision of an MD or DO. Injecting medication or substances is the practice of medicine and is outside the esthetician scope entirely.
Who can operate a cosmetic laser in Washington?
Use of a laser, light, radiofrequency, or plasma (LLRP) device on skin is the practice of medicine in Washington. An MD or DO (or a PA under WAC 246-918-125) may perform it or delegate it, under a written office protocol, to a properly trained and licensed professional whose licensure and scope permit LLRP use — which includes RNs and can include estheticians operating under MD/DO supervision (WAC 246-919-605). The physician must complete the pre-treatment history/exam/diagnosis/consent, be on the immediate premises during the initial treatment, and remains ultimately responsible for patient safety; the device may not be used on the eye globe.

What are the rules for IV therapy and vitamin drips in Washington?
There is no IV-therapy-specific med-spa statute. A competent, appropriately trained registered nurse may insert/remove peripheral and central vascular access devices and administer IV infusion fluids and medications, but these invasive procedures require an order from an authorized health care practitioner (MD, DO, ARNP, or PA), and the infused substances are prescription items requiring a prescriber (WA Board of Nursing infusion/VAD guidance). LPNs may perform limited infusion tasks after documented competency. Because IV vitamin/hydration drips involve prescription medications and invasive access, they must be ordered by an authorized prescriber and administered by qualified licensed staff.
Does a med spa have to register or hold a license in Washington?
Washington does not require a med spa, as a facility, to obtain a separate state registration or med-spa license. DOH guidance frames all requirements around the individual licenses of the people working there (MD/DO, ARNP, PA, RN, esthetician, etc.) and around keeping each person within their legal scope, not around registering the establishment. Operators must instead ensure each service is delivered by an appropriately licensed practitioner and, where medical procedures are delegated, under a responsible supervising physician.
What are the penalties for practicing outside scope in Washington?
Med-spa violations are enforced through the Uniform Disciplinary Act (chapter 18.130 RCW). Practicing a health profession — including performing medical cosmetic procedures — without the required license can draw a cease-and-desist order plus a civil fine up to $1,000 per day; a single violation is a gross misdemeanor and each subsequent violation is a class C felony punishable under chapter 9A.20 RCW (RCW 18.130.190). Licensed practitioners who exceed scope or act negligently face discipline for unprofessional conduct under RCW 18.130.180, including license suspension or revocation and fines, and DOH warns that letting a person exceed scope can result in discipline against the medical director, supervisor, and the individual.
