Who Is Allowed to Inject You in Colorado?

In Colorado, a cosmetic injection is the practice of medicine. Whether it's Botox or filler, everything about who is allowed to inject you follows from that one fact.

Most people book an injectable the way they book a haircut. You find a place, you like the photos, you go. If you've ever wondered who'd be holding the syringe, you don't have to go digging. Colorado writes it down, in public, in more detail than most patients expect.

Why is a cosmetic injection the practice of medicine in Colorado?

The Colorado Medical Board defines medical-aesthetic services to include injecting any substance into the human body, along with Class IIIb or higher lasers, radiofrequency devices and intense pulsed light. Those are medical services. Performing one is practicing medicine, and that takes either a license that covers it or a formal delegation from someone whose license does.

That's also why the product in the syringe is a prescription drug. The Board's rules say prescribing can't be delegated at all, so the person deciding what goes into your face, and how much, has to be licensed to make that call.

Microdermabrasion, superficial exfoliating treatments and the services covered by Colorado's cosmetology rules sit outside the Medical Practice Act. A facial isn't a medical service. An injection is.

Which Colorado licenses allow someone to inject you?

Physicians, meaning an MD or a DO, can inject, and can delegate injecting under the conditions below.

Nurse practitioners practice independently in Colorado. The Board of Nursing states that advanced practice nursing doesn't require supervision, and that Botox injections may fall within advanced practice scope where the nurse has the knowledge, judgment and ability to perform them safely. Prescribing is handled separately: an advanced practice registered nurse holds provisional prescriptive authority until completing 750 hours of documented prescribing mentorship.

Physician assistants haven't been required to practice under physician supervision since August 7, 2023. A PA now works under a written collaborative agreement with a physician, podiatrist or physician group, and that collaborating physician has to be licensed in good standing in Colorado with a regular and reliable physical presence in the state. PAs with fewer than 5,000 practice hours, or fewer than 3,000 hours in a new practice area, work under a supervisory agreement instead. I hold a PA-C license myself, so this is the framework my own injecting sits inside.

Registered nurses inject as what Colorado calls a delegated medical function. The Board of Nursing says Botox injections may be within RN scope on that basis, assuming competence and accepted standards of practice. That function is performed under the responsible direction and supervision of someone licensed to practice medicine, podiatry or dentistry. An RN injector isn't working on their own authority; there's a physician attached to that work, by name.

Licensed practical nurses are a clear line. Botox injections aren't within the LPN scope of practice in Colorado, and the Board of Nursing says so directly.

Can an esthetician inject Botox in Colorado?

The phrase medical aesthetician gets used loosely, and Colorado addresses it head on. Board rules say a delegatee who is an aesthetician may not use the word medical as part of a title when they aren't licensed, registered or certified by the state to perform medical services.

An esthetician license doesn't authorize injecting. Estheticians are good at what their license covers, and that work matters: a great facial leaves your skin smooth and your shoulders down. It's a different category from a medical service.

Colorado does allow a physician to delegate a medical-aesthetic service to someone not licensed to perform it, and that person can be an esthetician. The conditions are detailed. The delegating physician must be qualified to perform the service, must be performing it in their own practice rather than only handing it off, must watch the delegatee do it over the shoulder before letting them work unsupervised, must be reachable within Colorado, and must review the chart of every patient the delegatee treats within fourteen days. Written procedure and emergency protocols are required any time the physician isn't on site, and monitoring happens in person, where the work is done, at least every two weeks.

That's a real structure, not a formality. And when a practice uses it, Colorado now requires it to say so out loud.

What does Colorado law require a practice to tell you?

House Bill 25-1024 was signed on April 7, 2025 and took effect at 12:01 a.m. on August 6, 2025. It added two matching sections to Colorado law, one covering physicians and one covering advanced practice registered nurses. Both require three disclosures when medical-aesthetic services are delegated to someone who isn't a licensed health-care provider.

First, a notice posted in a highly visible manner where the delegated services happen, showing the licensee's name, Colorado license number, contact information, and an online address where a patient can file a complaint with the board.

Second, a notice on the public website and on all advertising materials of the unlicensed individual, stating that medical-aesthetic services are delegated and naming the licensee and license number.

Third, an informed consent form the patient signs, stating that they're receiving medical-aesthetic services delegated to an unlicensed individual by a licensed one, and carrying the same information as the posted notice. The practice keeps each signed form for at least seven years.

The law puts the work on the practice, not on you. The disclosure is built to arrive on its own, in the waiting room, on the website, and on the paperwork in your hand, so nobody has to play investigator to find out who's treating them. The law changed what has to be said, not who is permitted to delegate.

What are Colorado lawmakers considering next?

Two 2026 bills would have gone further, and neither became law.

HB26-1249 would have allowed estheticians, cosmetologists, nurses and physician assistants to hold ownership in a corporation formed solely to provide medical-aesthetic services. Under current law, shareholders of a medical professional service corporation must be physicians, and a physician assistant may hold shares but not a majority. The House Health and Human Services Committee postponed the bill indefinitely on March 25, 2026, on a 13 to 0 vote.

SB26-130, titled the Medical Spa Prescription Drug Consumer Protection Act, would have made it a deceptive trade practice for a med spa to let someone prescribe or administer prescription drugs outside their state credential, or to operate without a licensed provider with prescriptive authority providing clinical oversight. It was introduced on February 25, 2026 and didn't pass before the General Assembly adjourned on May 13, 2026.

Neither bill is in effect. As of September 2026, the rules described above are the ones that apply.

What this looks like at Redbud

Redbud is a small, provider-led practice in Denver, and every injectable visit starts the same way. A licensed provider sits down with you in a warm room, goes through your face, your history and your goals, and gives you a straight read on whether an injectable is the right answer that day. Nothing gets drawn up before that conversation. Plenty of people arrive a little nervous, and that's welcome. You'll know the name and the credential of the person holding the syringe, because they're the one who assessed you. The look we aim for is rested, not different.

Credentials are on our providers page. If you're still comparing places, how to choose a medical spa in Denver covers the wider picture, medical spa vs day spa draws the same line, and what to expect at your first visit walks through the appointment.
