Who can inject Botox in Brazil: what the law allows

Who can inject Botox in Brazil looks like a simple question, and the answer circulates wrong. Some say only physicians can. Others sell weekend courses promising to qualify anyone. Both are false, and the gap between them is expensive.

The correct answer rests on one distinction: injecting botulinum toxin is a healthcare act, not a beauty service. It is an injectable procedure, with a prescription product, in an anatomical region full of vessels and nerves. Who may perform it is defined by the professional council governing each category — not by the practitioner's own judgment, and not by the certificate from whatever course they took.

Which professionals can inject Botox?

In Brazil, injecting botulinum toxin for aesthetic purposes falls within the scope of several university-level health professions, each with its own limits set by its council:

• Physician — no restriction by anatomical region, under Law 12.842/2013, which defines the acts reserved to medicine.
• Dentist — within the head and neck region, with Orofacial Harmonization recognized as a dental specialty by CFO Resolution 198/2019.
• Biomedical scientist, nurse and pharmacist — within the limits each professional council has set for aesthetic practice.

What they all share is a university degree in a health field and licensure from the corresponding council. The injection course is not what qualifies anyone. The degree does, plus registration with the council, plus the specialization that council recognizes.

What changes from one professional to another

Scope. A dermatologist, a dentist specialized in Orofacial Harmonization and a biomedical scientist working in aesthetics can all inject botulinum toxin in the face — but what each of them may do beyond that, and in which region, differs.

For dentists, the limit is explicit. CFO Resolution 230/2020 confines practice to the head and neck and expressly bars surgical procedures such as blepharoplasty, rhinoplasty, otoplasty, rhytidectomy and brow lift. A dentist offering any of those is outside the scope of the profession, whatever course they have taken.

That clarity is an advantage for the person choosing: it can be verified.

Can an esthetician inject Botox?

No.

Law 13.643/2018, which regulates the professions of esthetician and esthetics technician, defines a field of practice that does not include invasive procedures. Botulinum toxin and fillers are injectables — they cross the skin barrier, introduce substance into tissue and carry vascular risk.

This does not diminish the profession. Esthetics and cosmetics have their own field, legitimate and extensive: facial cleansing, superficial peels, protocols with non-invasive devices, long-term skin care. A good esthetics professional is a real part of the result for anyone taking care of their face.

What the law says is that injectables are not in that field.

What about the courses that promise to qualify you?

A course does not confer legal competence. It supplements training that already exists.

A botulinum toxin course is a continuing-education tool for an already licensed professional. Sold to someone with no health degree and no council registration, it creates no authorization at all — it merely teaches a technique that person cannot legally perform.

If a course promises to "qualify" someone with no university degree in a health field, the problem is not its length. It is the premise.

Can a dentist do facial harmonization?

Yes, and the regulatory basis is specific.

CFO Resolution 198/2019 recognized Orofacial Harmonization as a dental specialty. CFO Resolution 230/2020 detailed the limits of that practice, confining it to the head and neck and listing the surgical procedures that are barred.

The logic behind it is anatomical, not commercial. Of all health degrees, dentistry devotes the most time to head and neck anatomy — facial musculature, innervation, vascularization, dissection planes, the relationship between bone structure and soft tissue. It is the profession's daily working territory.

Injecting toxin into the masseter for bruxism, treating a gummy smile, understanding how occlusion and the chewing muscles alter facial contour: these are subjects where dental training is not adjacent to the problem, it is central to it.

What the CFO did in recognizing the specialty was not to expand dentistry beyond its field. It was to formalize a practice already inside it.

What training is required to inject Botox?

Three layers, in this order:

1. A university degree in a health field whose council recognizes the practice.

2. Active registration with the corresponding professional council — CRM (medicine), CRO (dentistry), CRBM (biomedicine), COREN (nursing), CRF (pharmacy).

3. Specialization or specific licensure recognized by that council, when required for the intended practice.

The third layer causes the most confusion, because "specialist" has a legal meaning. Advertising yourself as a specialist in something that is not a title registered with your council is an advertising violation, even if you did take the course.

How to check before you book

This is public information and takes two minutes:

• Ask for the council registration number. CRO, CRM, CRBM, COREN or CRF, with the state abbreviation.
• Look it up on the council's website. All of them keep a public professional search. Confirm the registration is active and under which category.
• Check the registered specialty, not the advertised one. They are different things.
• Confirm who does the injecting. In some clinics, the person who assesses you is not the person who injects. You have a right to know the name and registration of whoever puts a needle in your face.
• Ask what happens if something goes wrong. A prepared professional answers on the spot, with product names and protocols — hyaluronidase available on site, a plan for a vascular event, a contact number outside business hours. Anyone who hesitates on that question has not thought about it before.

When we decline the case

Not every question about "who can inject" comes from the person receiving treatment. Some come from the person wanting to inject — and the same criterion applies.

We do not do the following, and we recommend nobody accept it:

• Treatment outside a clinical setting. Homes, salons, events. A vascular event needs structure and materials available within minutes.
• A procedure with no prior assessment. Consultation and injection in the same breath, with no history taken, is a sale — not an indication.
• A product with no verifiable provenance. Anvisa registration, batch number and expiry date, all checkable. An already-opened or unlabeled vial is reason to stop.
• A procedure outside the scope of the profession of whoever is injecting. That applies to us too: a case requiring treatment outside the head and neck gets referred, not improvised.

Frequently asked questions

Have estheticians been cleared to inject Botox?

No. Law 13.643/2018 does not authorize invasive procedures for estheticians, and nothing has changed that. Claims to the contrary circulate often, usually attached to someone selling a course.

Can someone with an esthetics course inject Botox?

No, if "esthetics course" means technical or vocational training in esthetics and cosmetics. Licensure comes from a health degree plus council registration, not from an injection course.

Can a dentist inject Botox anywhere on the face?

Within the head and neck, yes, under the scope of Orofacial Harmonization. Surgical procedures listed as barred by CFO Resolution 230/2020, and areas outside the head and neck, are out of scope.

Which professional is best for facial harmonization?

The better question is a different one: who has active registration, a matching registered specialty, command of the anatomy of the region, and the structure to handle a complication. That exists in more than one professional category, and it does not exist in every professional in any of them.

How do I know whether a professional is registered?

A public search on the council's website, by name or registration number. It is free and immediate.
