How long do I have to sue a clinic or aesthetic physician?

As a general rule, Brazil's Consumer Protection Code (CDC) sets a 5-year statute of limitations for claims seeking compensation for damages caused by a defective product or service, counted from the moment the victim becomes aware of the damage and who caused it. This period can vary depending on the specific circumstances of the case, so it's best to consult a lawyer as soon as you notice the problem, to assess the deadline that applies to your specific situation.

Do I need a medical report to file a lawsuit?

A medical report or expert opinion is very helpful in proving the causal link between the procedure and the harm suffered, but it isn't the only possible type of evidence. Photos, messages exchanged with the clinic, medical records, prescriptions and witness statements can also form part of the body of evidence. A lawyer can advise on which evidence to gather and, if necessary, request a court-ordered expert examination.

Can I sue even though I signed an informed consent form?

Yes. The informed consent form proves that you were told about the general risks of the procedure, but it does not release the professional or the clinic from liability in the event of technical error, negligence, recklessness, malpractice, or a failure in the provision of the service. The existence of the consent form does not, by itself, prevent a civil liability lawsuit.

Do the aesthetic clinic and the physician answer for damages in the same way?

Not necessarily. The clinic, as a service provider, is generally held strictly liable under Brazil's Consumer Protection Code, regardless of fault. The physician's personal liability, on the other hand, is generally assessed based on fault (negligence, recklessness, or malpractice), except when the case involves an obligation of result, as is often understood to be the case in cosmetic plastic surgery. A lawyer can assess who should be named as a defendant in the lawsuit.

Patient Rights in Cosmetic Procedures: The Complete Guide

Going through a cosmetic procedure — whether a hair transplant, plastic surgery, a filler session, or facial harmonization — usually involves expectation, financial investment, and, often, a degree of vulnerability. When the result deviates from what was agreed or an unexpected complication arises, it’s natural to feel a mix of frustration, insecurity, and uncertainty about what to do next.

The first important thing to understand is that not every unsatisfactory result amounts to an error, but not every unsatisfactory result is simply a “risk of the procedure” that the patient must simply accept. There is a meaningful legal difference between an inherent risk, disclosed in advance and assumed by the patient, and a technical failure, negligence, or a breach of the duty to inform by the professional or the clinic. This guide exists to help you understand that difference — without promising a result, but with clear information for an informed decision.

What may constitute an error or failure in a cosmetic procedure

In general, the civil liability of a healthcare professional or an aesthetic clinic can be discussed when there is:

Technical failure in the execution of the procedure (for example, avoidable asymmetries, necrosis caused by poor technique, or injuries to structures that should not have been affected);
Negligence in pre- or post-operative care (lack of proper guidance, absence of follow-up in the event of a complication);
Failure in the duty to inform, when the patient was not properly advised about actual risks, limitations of the procedure, or existing alternatives;
Infections and complications resulting from asepsis failures or an inadequate environment;
Misleading advertising, when the result promised in the service’s marketing is technically unattainable or distorts what can realistically be delivered.

Each case requires its own analysis, considering documents, photos, medical records, and, often, specialized technical assessment. The presence of a complication, by itself, does not automatically determine who is responsible — but it is the starting point for that investigation.

Physician civil liability: obligation of means or of result?

One of the central points in discussions about errors in cosmetic procedures is the difference between an obligation of means and an obligation of result.

In medicine generally, the prevailing understanding is that the physician assumes an obligation of means: they commit to employing all available care, techniques and diligence to try to achieve the best possible outcome, but they do not guarantee a specific outcome, since the human body responds in a particular way to each treatment.

When it comes to purely cosmetic plastic surgery — that is, surgery with a strictly aesthetic purpose, without a reparative or curative function — a significant part of Brazilian legal scholarship and case law has traditionally treated this relationship as closer to an obligation of result: since the patient is seeking a specific, defined aesthetic effect, the professional assumes, to a greater degree, the commitment to deliver what was promised, which can make it easier to discuss liability when the result is substantially different from what was agreed. In reparative surgeries (such as those resulting from accidents, burns, or post-bariatric procedures), the tendency is to treat the relationship as an obligation of means, given the greater clinical complexity involved.

This distinction is neither automatic nor definitive — it is analyzed case by case, taking into account the purpose of the procedure, what was promised, the documents signed, and the evidence produced. This is precisely why an individualized legal assessment is important before drawing conclusions about your case.

The liability of the aesthetic clinic

Beyond the professional who performs the procedure, the clinic or establishment where it takes place may also be held liable. As a service provider in the consumer market, the clinic is generally held strictly liable — that is, regardless of proof of fault — for defects in the provision of the service, under Brazil’s Consumer Protection Code (CDC). This includes, for example, structural failures, lack of adequate equipment, professionals without the required qualifications, or a breach of the duty to inform in the marketing of its services.

In many cases, the physician and the clinic may be held jointly and severally liable, meaning the patient can direct the lawsuit against both, leaving them to later resolve between themselves any division of responsibility.

The Consumer Protection Code and the consumer relationship

When a cosmetic procedure is contracted as a service — especially at clinics and aesthetic chains — the relationship between patient and provider is generally treated as a consumer relationship, subject to the CDC. This brings important protections for the patient, including:

The duty of clear and adequate information about the service, its risks, limitations and costs;
The prohibition of misleading or abusive advertising that promises results that don’t match the technical reality of the procedure;
The possibility of the strict liability of the supplier for a defect in the provision of the service, without the need to prove the clinic’s fault;
The facilitation of consumer defense in court, including the possibility of shifting the burden of proof under certain conditions.

What is the deadline for suing a clinic or physician?

Brazil’s Consumer Protection Code generally sets a 5 (five) year statute of limitations for claims seeking compensation for damages caused by a defective product or service, counted from the moment the harm and its cause become known. This period, however, can vary depending on the nature of the claim, who is being sued, and the specific circumstances of the case — so it’s important not to wait until the deadline is close before seeking legal guidance.

If you identified a problem recently, but the procedure was performed some time ago, it’s worth talking to a lawyer as soon as possible to precisely assess the deadline that applies to your situation.

How to prove an error in a cosmetic procedure

Evidence is one of the most important points — and one of the most common sources of doubt — in cases like this. Some elements tend to be especially relevant:

Photos and videos from before, during the healing process, and after the procedure;
Medical records and other documents provided by the clinic;
Messages, emails or WhatsApp conversations with the clinic or professional, especially about what was promised;
Reports, medical opinions or expert examinations linking the harm to the procedure performed;
Proof of payment and the contract or signed informed consent form.

It’s also worth remembering that Brazil’s Consumer Protection Code allows, under certain conditions, the burden of proof to be shifted in favor of the consumer, when the plausibility of the allegations or the consumer’s technical disadvantage relative to the clinic is present. This means that, instead of the patient having to prove everything alone, the clinic may be required to demonstrate that it acted correctly.

A signed informed consent form does not, by itself, take away the patient’s right to seek compensation — it only proves that there was disclosure about the general risks of the procedure, but it does not protect the professional in the event of technical error, negligence, or a result far from what was agreed.

Moral damage and aesthetic damage: what’s the difference?

In cases of cosmetic procedure error, it’s common for both moral damage and aesthetic damage to be discussed, which are recognized as distinct categories, even though they can be combined in the same lawsuit:

Aesthetic damage relates to permanent or lasting physical changes that affect a person’s appearance — scars, deformities, asymmetries;
Moral damage relates to emotional distress, psychological suffering, and the impact on self-esteem and on social and professional life caused by the situation.

The amount of any compensation depends on an individualized analysis of each case, taking into account the extent of the harm, the circumstances involved, and the evidence produced. It is not possible — nor correct — to estimate amounts without knowing the specific case, and any promise of a result or a fixed amount before this analysis should be viewed with caution.

What to do if something went wrong with your procedure

Seek medical attention as soon as you notice any sign of a complication, prioritizing your health;
Document everything — photos, symptoms, dates, and conversations with the clinic, from the very first sign that something wasn’t right;
Request your complete medical records and other documents related to the procedure from the clinic;
Avoid rushed verbal settlements proposed by the clinic itself before you understand your rights;
Seek specialized legal guidance to assess your case and the possible paths forward, including a possible complaint to bodies such as the Federal Council of Medicine (CFM) or the Health Surveillance Agency (Vigilância Sanitária), when applicable.
