Quick answer Cosmetic surgery on a minor in Korea requires informed consent from the patient's legal representative, normally a parent, in addition to the clinic's own assessment of whether the procedure is appropriate at all. Korea sets the age of majority at nineteen under its Civil Act, and the Medical Service Act requires that the explanation of a planned operation and its risks be given to the legal representative where the patient cannot consent independently. Many clinics decline certain procedures before skeletal maturity regardless of parental consent.

The age of majority in Korea, and what it changes
Korea's Civil Act sets the age of majority at nineteen, counted in full years, which is lower than in some countries and higher than in others. Below that threshold a patient generally cannot give legally effective consent to a surgical procedure on their own behalf, and the authority to consent sits with the legal representative. This is the structural point families most often misunderstand: the question is not whether a teenager feels ready, nor whether they are close to a birthday, but whether the person signing has legal authority to do so on the day of surgery.
There is no single Korean statute that bans cosmetic surgery on minors outright, which differs from the position proposed or adopted in some neighbouring jurisdictions. What exists instead is a layered framework. The Civil Act determines who may consent. The Medical Service Act governs how the explanation of a procedure and its risks must be given. Professional bodies and individual clinics then apply their own, often stricter, eligibility policies on top. A family can satisfy the legal requirement and still be declined on clinical grounds, and that is a normal and appropriate outcome.
Who counts as a legal representative, and what documents prove it
In the ordinary case the legal representative is a parent exercising parental authority. Where parents are divorced or separated, where one parent has died, or where a guardian has been appointed, the position becomes document-dependent rather than obvious, and a clinic cannot be expected to resolve it from a verbal explanation. The practical consequence for international families is that proof of the relationship, translated and where required apostilled or legalised, should be assembled before travel rather than at the reception desk.
Clinics differ in what they accept, so confirm the list in writing with the specific clinic. The table below sets out what is commonly requested. Where the accompanying adult is not the person with authority to consent, a notarised authorisation from the legal representative is usually required, and some clinics will not accept it for procedures under general anaesthesia at all. Our guide to consent forms and treatment contracts at Korean clinics explains what the consent document itself covers once eligibility is settled.
Document | Why a clinic asks for it | Common complication |
Minor's passport | Identity and date of birth | Age calculated differently from the home country |
Proof of parent-child relationship | Establishes parental authority | Needs certified translation; sometimes apostille |
Both parents' identification | Some clinics require joint consent | One parent unavailable or overseas |
Court order or guardianship papers | Where parental authority is modified | Rarely available on short notice |
Notarised authorisation | Where the accompanying adult is not the parent | May still be refused for general anaesthesia |
Medical history and growth records | Clinical eligibility assessment | Often not brought from the home country |
Procedures clinics commonly decline before skeletal maturity
Consent is only the first gate. The second is whether the procedure makes clinical sense in a body that is still changing. Facial bone surgery is the clearest example: zygoma reduction, mandible contouring and orthognathic jaw surgery depend on the facial skeleton having finished growing, and operating before that point risks a result that drifts as growth continues. Rhinoplasty raises the same issue, because the nasal septum contains growth centres and surgery around them in a growing patient is approached with considerably more caution.
Procedures involving implants or permanent tissue removal also carry a long time horizon that a sixteen-year-old cannot easily evaluate. Breast augmentation, permanent fat removal and anything requiring lifelong maintenance or eventual replacement are commonly deferred. By contrast, reconstructive and functional indications are treated differently: correction of ptosis that impairs vision, repair after trauma, or treatment of a congenital difference are medical rather than cosmetic questions, and the consent framework is the same but the clinical reasoning is not. Our guide to ptosis correction and how it differs from double eyelid surgery illustrates how functional and cosmetic indications diverge.

What a responsible consultation looks like
A consultation involving a minor should look different from an adult consultation, and if it does not, that is information. Expect the surgeon to speak with the young person separately at some point, to ask who initiated the request, to ask what the patient expects the result to change in their life, and to screen for the possibility that the motivation sits outside the appearance itself. Expect a discussion of growth status, not just of technique. Expect at least one clear statement of what the operation cannot do.
Pressure in the other direction is the warning sign. A clinic that offers a same-day surgery slot to a teenager, that discourages the minor from asking questions, that frames a procedure as a corrective to bullying or to a relationship problem, or that presents a result as guaranteed is not following any defensible standard. Korean professional bodies including the Korean Medical Association and the Korean Society of Plastic and Reconstructive Surgeons publish guidance on advertising and informed consent that is worth reading as a benchmark for what you should be hearing.
Important A young person's physical growth, and their judgment about permanent changes to their own body, are both still developing. Deferring an elective cosmetic procedure costs very little; an irreversible operation performed too early can cost a great deal. If a family is uncertain, waiting and seeking a second independent opinion is almost always the lower-risk choice, and no reputable surgeon will object to it. |
Travelling to Korea with a minor patient
International families face a second layer of paperwork on top of the clinical one. Airlines apply their own rules to minors travelling with one parent or with a non-parent adult, and several require a signed parental consent form. Immigration officers in both directions may ask about the relationship. If a Korean medical visa is involved, the minor and the accompanying adult are normally separate applications, and the clinic's treatment plan must name the patient correctly.
Plan the stay around the follow-up schedule, not the flight price. Our procedure-by-procedure day count sets out indicative windows, and recovery accommodation in Seoul covers what to look for when an adult will be providing care in the room. Note also that school absence, examination timetables and sports commitments are genuine clinical inputs, not logistics: a procedure that needs three weeks of restricted activity should not be scheduled a week before a competition.
Records, aftercare and what to keep
Leave Korea with the operation record, the names and lot numbers of anything implanted or injected, the medication list and the consent documents you signed. For a minor this archive matters more than it does for an adult, because a decision made at seventeen may need to be explained to a different doctor at twenty-five, in a different country and a different language. Ask whether records can be released in English, and keep digital copies in more than one place.
Remote follow-up has to be arranged in advance, and for a minor the clinic should be clear about who it will communicate with. Our guide to remote follow-up after returning home covers the mechanics, and the revision policy should be read closely, since a revision in a growing patient may be clinically necessary rather than optional. If something looks wrong, our notes on medical dispute resolution in Korea set out the formal routes available to foreign patients.
Frequently asked questions
At what age can someone consent to cosmetic surgery in Korea without a parent?
Korea's Civil Act sets the age of majority at nineteen in full years, so below that age consent is generally given by the legal representative rather than the patient. Clinics may also apply their own minimum ages above the legal threshold for particular procedures, so confirm the specific clinic's policy in writing.
Is parental consent alone enough to proceed?
No. Consent from the legal representative satisfies the legal requirement, but the clinic still has to decide whether the procedure is clinically appropriate. Many clinics decline facial bone surgery, rhinoplasty and implant-based procedures before skeletal maturity regardless of parental consent, and that refusal is a sign the clinic is applying a standard rather than a problem to work around.
Do both parents have to sign?
Practice varies between clinics, and the answer can also depend on the family's legal situation. Some clinics require both parents, some accept one with documentation, and arrangements after divorce or separation are document-dependent. Ask the clinic for its requirement in writing before travelling, because resolving this at reception on the day is not realistic.
Can a grandparent, aunt or family friend consent instead?
Usually not on their own authority. Where the accompanying adult is not the legal representative, a notarised authorisation from the legal representative is normally required, and some clinics will not accept delegated consent at all for procedures under general anaesthesia. Confirm before booking flights.
What about functional surgery, such as ptosis that affects vision?
Functional and reconstructive indications are treated as medical rather than cosmetic questions, and the clinical reasoning is different even though the consent framework is the same. These cases are often appropriate in younger patients where a purely cosmetic equivalent would not be. An assessment by a specialist is the only way to establish which category a particular case falls into.
