Medical Spa vs Day Spa: What's the Difference?

A day spa provides cosmetic services. A medical spa provides medical services in a spa setting. In Colorado that difference is not marketing language, it is the line between work licensed under the state's cosmetology rules and work that legally counts as the practice of medicine.

Both are real, both are licensed, and they answer different needs. A facial, a wax and a massage are not lesser versions of a med spa treatment. The two can look identical from the sidewalk. But the moment a service goes below the surface of your skin or involves a prescription, Colorado treats it as medicine.

What is a medical spa?

A medical spa is a setting where aesthetic medicine is delivered by a licensed medical professional, or by someone working under a physician's authority in the way state rules require.

Colorado does not license "medical spa" as a facility type. What matters is whether the service you are getting falls inside the practice of medicine, which the law defines to include "prescribing, or administering any form of treatment" for a person's disease, ailment, injury or condition (C.R.S. 12-240-107(1)(b)).

The Colorado Medical Board has a name for the aesthetic version. Rule 1.17, long known as Rule 800, defines "Medical-Aesthetic Services" as cosmetic services that constitute the practice of medicine.

What is a day spa, and what can an esthetician do?

A day spa provides cosmetic and relaxation services performed by licensed estheticians and cosmetologists, and by massage therapists, who hold a separate Colorado license. These are real licenses with real training requirements behind them.

Colorado defines an esthetician as a person who gives facials and skin care, applies makeup, and removes hair by wax or tweezers, "not for the treatment of disease or physical ailments" (C.R.S. 12-105-104(8)). With documented extra training, a cosmetology licensee may also perform superficial chemical peels (24 hours of coursework first) and microdermabrasion (14 hours).

There is one bright line inside that license: the epidermis, the outermost layer of skin, the part that flakes off after a sunburn. State rule bars a licensee from using anything that results in "the removal, destruction, incision, or piercing of a client's skin beyond the epidermis," and calls any such act an invasive procedure (4 CCR 731-1, Rule 1.9(D)(4)).

Cosmetology licensees work on the epidermis and above it. Anything that goes through it is a medical service. A licensee also may not use a peel substance that requires a licensed healthcare provider, which is why your esthetician cannot do the stronger peel. That is about scope, not skill.

Which treatments legally require a medical professional?

Injecting any substance into the body is one. So is using a Class IIIb or higher laser, a radio-frequency device or intense pulsed light to alter tissue or remove hair (3 CCR 713-1, Rule 1.17(D)(2) and (D)(3)). If you are getting either of those, you are getting medical care, whatever the room looks like.

Federal rules point the same way. Botulinum toxin products are prescription drugs. BOTOX Cosmetic is FDA-approved in adults for temporary improvement in the appearance of moderate to severe glabellar lines, lateral canthal lines, forehead lines and platysma bands, and it is not approved as a general anti-aging treatment. The FDA regulates dermal fillers as medical devices, approved for adults 22 and older and supplied by prescription for injection by a licensed health care professional. The FDA's own wording is that having filler injected "should be considered a medical procedure, not a cosmetic treatment."

Colorado is equally clear about what is not medical: microdermabrasion, superficial exfoliation, other superficial skin treatments, and the use of Class I, II and IIIa devices (Rule 1.17(D)(4)(c) and (d)).

That is why one treatment name can mean two things. The FDA says some microneedling products may not be medical devices, generally those that do not penetrate the living skin layers and make only cosmetic claims.

Who is allowed to inject Botox and filler in Colorado?

This is the question most people come in with. There is no separate injector license in Colorado. Because injecting is the practice of medicine, the authority comes through one of four routes.

A physician can do it personally. A physician assistant can do it under a collaborative agreement with a physician or physician group, kept on file at the PA's primary practice location. A nurse can do it as a delegated medical function, which by statute follows a physician's, dentist's or podiatrist's medical plan, under the supervision of a licensed health-care provider. An advanced practice registered nurse on the state registry may be granted prescriptive authority by the Board of Nursing.

An unlicensed person may perform a delegated medical-aesthetic service, but only under a physician's personal and responsible direction and supervision. Prescribing may never be delegated. So the rules land on that physician. They have to be qualified and insured for the service. They have to be actively performing it in their own practice, not only handing it off. They have to be available in the community. Before the delegatee works alone, the physician watches them do the treatment. After that, the physician monitors the work on site every two weeks and reviews every patient's care within fourteen days.

How can you tell which kind of place you are in?

Four things settle the category.

The license of the person treating you is the whole answer. Physician, physician assistant, nurse, esthetician, cosmetologist and massage therapist are six licenses with six different scopes.

Behind any medical service is a named person with the legal authority to perform or delegate it, either the provider treating you or a delegating physician supervising them, not just a business.

The third thing is one you can see for yourself, standing in the lobby. Where unlicensed delegatees perform medical-aesthetic services, state rule requires the delegating physician's name and contact information to be posted in the reception area.

The fourth is a signed disclosure. Colorado requires one before a delegated treatment, not after, naming the treatment and everyone involved.

A visit starts with a conversation rather than a treatment menu, because a prescription-strength treatment is a medical decision first. Sometimes the right answer is a good facial and a steady routine at home, and we will say so. Wanting a med spa and loving your day spa are not in conflict. What to Expect at Your First Visit walks through a first appointment.

Frequently asked questions

Is a med spa the same as a dermatologist's office?

No. A dermatologist is a physician who diagnoses and treats skin disease. A medical spa is a setting where aesthetic medical services are delivered, under a physician, a physician assistant or an advanced practice nurse. Colorado regulates the service and the license behind it, not the sign on the door.

Can an esthetician give me Botox in Colorado?

Not on an esthetician license. Injecting any substance is the practice of medicine here, so it can only happen through a physician, a physician assistant, a nurse performing a delegated medical function, or a properly delegated person working under a physician who meets Rule 1.17.

Do I need a med spa or a day spa?

Match the goal to the category. For relaxation, maintenance, hydration and glow, a day spa does that job well. For softening lines with a neurotoxin, restoring volume, resurfacing scars or treating pigment with a medical laser, you need a medical spa. Our FAQ page covers candidacy and downtime.
