Note №2PATIENT COMPLAINTS
In the Korea Consumer Agency’s analysis of 322 redress applications concerning cosmetic and aesthetic medical services, 163 (50.6%) were contract disputes and 124 (38.5%) concerned adverse effects. The largest single group within the contract cases was refusal to refund a prepayment. Where a clinic justified that refusal with a signed no-refund form, the agency’s position is that the clause is void.
Foreign patients arriving for skin or cosmetic work tend to worry about the same thing: something going wrong on the table. Scarring, asymmetry, a burn from a laser.
Korea’s consumer regulator keeps records of what people actually complain about. Those records say something different. The most common dispute is not medical. It is about money you already paid and cannot get back.
Where these numbers come from
The Korea Consumer Agency (한국소비자원) is a government body that takes consumer redress applications and publishes analyses of them. In May 2021 it published a study of 322 redress applications concerning cosmetic and aesthetic medical services, filed over 2019 and 2020. Over the same two years, its call centre logged 10,213 consultations tagged to plastic surgery or dermatology clinics.
Two limits, stated up front:
- These are complaints filed in Korean by consumers in Korea. The agency does not break the figures out by nationality, so this is not a foreign-patient dataset. It is the closest public record of what goes wrong in these clinics.
- Filed complaints are not a census of outcomes. They tell you what generates disputes, not how often treatment succeeds.
What do patients actually complain about?
| Type of complaint | Cases | Share |
|---|---|---|
| Contract-related | 163 | 50.6% |
| Adverse effects | 124 | 38.5% |
| Insufficient results | 23 | 7.2% |
| Other (misdiagnosis, delay) | 12 | 3.7% |
Contract disputes outnumber every medical category. Within those 163 contract cases, the pattern is narrow:
- Refusal to refund a prepayment — 97 cases (59.5%)
- Excessive deduction from the refund — 66 cases (40.5%)
Sixty-one of those refusals happened before the procedure had even started. The patient paid, changed their mind, and was told no.
Is a no-refund waiver enforceable in Korea? Probably not
This is the part worth carrying with you.
Of the 97 refund refusals, the clinic’s stated reason was:
| Reason given | Cases | Share |
|---|---|---|
| Patient signed a no-refund consent form | 31 | 31.9% |
| Patient was told verbally that refunds weren’t possible | 22 | 22.7% |
| Simple refusal, no reason | 15 | 15.5% |
| Other (refund window expired, event pricing, clinic policy, transfer only) | 29 | 29.9% |
More than half rested on a waiver — signed or spoken.
The Korea Consumer Agency’s position is that this does not hold. Article 689(1) of the Civil Act gives either party to a mandate contract the right to terminate at any time. A clause that removes or restricts that right is treated as void under Article 9(1) or 9(4) of the Act on the Regulation of Terms and Conditions. The Consumer Dispute Settlement Commission has ruled accordingly.
In plain terms: a clinic can hand you a no-refund form, you can sign it, and Korea’s own dispute body may still treat the clause as unenforceable. Signing it does not end the argument. It is the beginning of one you can win.
When it is medical, it is mostly the face
Of the 147 applications involving adverse effects or insufficient results:
| Procedure | Cases | Share |
|---|---|---|
| Eye surgery | 34 | 23.1% |
| Facial laser | 28 | 19.0% |
| Nose surgery | 15 | 10.2% |
| Botox | 13 | 8.8% |
| Filler | 11 | 7.5% |
| Contouring injection | 9 | 6.1% |
And what actually went wrong:
| Problem | Cases | Share |
|---|---|---|
| Scarring | 31 | 21.0% |
| Asymmetry | 21 | 14.3% |
| Inflammation | 21 | 14.3% |
| Insufficient result | 23 | 15.6% |
| Pigmentation | 14 | 9.5% |
| Burns | 5 | 3.4% |
Facial laser sits second on the list. It is also the treatment most often sold to visitors as low-risk and same-day.
The advertising finding that applies directly to you
The Korea Consumer Agency then went back and monitored the online advertising of the clinics these complaints were filed against. Of 226 clinics, 190 were advertising online. Seventy-one of them — 37.4% — were running advertising suspected of breaching Article 56 of the Medical Service Act. Ninety-two such advertisements were identified.
| Suspected breach | Ads | Share |
|---|---|---|
| Patient testimonials creating a false impression of efficacy | 32 | 34.8% |
| Use of awards, certificates, endorsements | 20 | 21.7% |
| Unregistered clinics advertising to attract foreign patients | 19 | 20.7% |
| Exaggerating objective fact | 13 | 14.1% |
| Claiming qualifications with no legal basis | 8 | 8.7% |
That third row is the one aimed at you. Article 56(2)12 of the Medical Service Act prohibits domestic advertising aimed at attracting foreign patients unless the clinic is registered to treat them. Nearly a fifth of the suspect advertising was clinics soliciting foreign patients they were not registered to take.
Registration is checkable before you book. We covered how, and what registration obliges a clinic to carry, in our note on malpractice insurance and the foreign-patient register.
Has the pattern changed since 2021?
The 2021 study is the most recent full analysis we have read in the original. The agency has since issued a consumer alert on prepaid treatment fees reporting a sharper version of the same pattern — roughly 1,198 prepayment-related redress applications between 2022 and the first quarter of 2025, with dermatology the single largest specialty at about 35.8%, and contract termination and penalty disputes accounting for about 83.7% of them.
We have not obtained that alert in its original form, so we present those figures as reported rather than verified. The direction, at least, matches: the argument is about the money.
What this changes about how you book
- Get the refund terms in writing before you pay, and keep the quote. The dispute you are most likely to have is this one.
- A no-refund clause is not the last word. Note the date, keep the paperwork, and know that the Consumer Dispute Settlement Commission has treated such clauses as void. That process is free to use, but it only guarantees you a hearing in three scenarios.
- Check the clinic is on the foreign-patient register before you accept marketing aimed at foreign patients.
- Prepaid packages are the highest-risk structure — most refusals in the data involved package or prepaid arrangements, and 61 refusals came before any treatment was given.
Common questions
Can I get a refund from a Korean clinic if I signed a no-refund form?
Signing one does not settle the question. Article 689(1) of the Civil Act lets either party to a mandate contract terminate at any time, and a clause removing that right is treated as void under Article 9(1) or 9(4) of the Act on the Regulation of Terms and Conditions. The Consumer Dispute Settlement Commission has ruled accordingly. This is the position of Korea’s consumer redress bodies, not legal advice on your own contract.
What is the most common complaint against Korean cosmetic clinics?
Contract disputes, not medical ones. In the Korea Consumer Agency’s analysis of 322 redress applications from 2019–2020, 163 (50.6%) were contract-related against 124 (38.5%) for adverse effects. Within the contract cases, 97 were refusals to refund a prepayment, and 61 of those refusals came before the procedure had even started.
Which procedures generate the most complaints?
Among the 147 applications involving adverse effects or insufficient results, eye surgery led with 34 cases (23.1%), followed by facial laser at 28 (19.0%) and nose surgery at 15 (10.2%). These are counts of filed complaints, not rates of harm — they do not tell you how often a treatment succeeds.
Are Korean clinics allowed to advertise to foreign patients?
Only if they are registered to treat them. Article 56(2)12 of the Medical Service Act prohibits domestic advertising aimed at attracting foreign patients from clinics without that registration. In the agency’s advertising monitoring, 19 of 92 suspect advertisements (20.7%) fell into this category. Registration is checkable before you book.
