Google Maps listing (reference, not scored)
What the clinic's public Google Maps listing showed when we read it: the rating other people gave, the number of their reviews and the hours the clinic itself publishes there. This block is a reference only — it does not enter the score, the rank, the ceilings or the holds, and we have not checked it beyond matching the listing to this record.

Axis by axis
rubric value 1–5 · ? could not verify (no points, not a negative finding) · — not applicable: this country has no register of that class · OFF official register · SEC secondary source
| Axis | Finding (rubric anchor) | Value | Source class | Weight | Checked |
|---|---|---|---|---|---|
| M1 | Specialist certification of the responsible physician Could not verify — this register is closed to machine queries in this country, so the axis is left out of the coverage calculation for every clinic on this site. Not a negative finding. Reason: Register closed to machine queries. Last attempt: kspgrs, 22 September 2026 — class registry_closed in jurisdiction national (state portal login-gated from two egresses); the society listing is shown as a fact Physician found in the national plastic-surgery specialist-society directory; facility register shows 5 of 7 physicians as 성형외과 (plastic surgery) specialists at this address. |

| M2 | Identifiability of the responsible physician Physician(s) named with role and tied to this address. |
SEC | 16 | 2026-08-29 | |
| M3 | Basic medical licence Could not verify — this register is closed to machine queries in this country, so the axis is left out of the coverage calculation for every clinic on this site. Not a negative finding. Reason: Register closed to machine queries. Last attempt: mohw_sanctions, 20 September 2026 — Korea has no anonymous licence search: lic.mohw.go.kr was re-probed on 2026-09-20 and the register function still requires the holder’s own sign-in (see registry-map medical_licence.closedAttempt). Secondary routes run for this record: mohw_sanctions — HTTP 200, both disclosure cycles read row by row; neither the institution nor the physician appears, so that register publishes no 대표자의면허번호 for this physician, and an absence there says nothing about the licence. ksprs_roster and hira_specialists answered but carry no licence number, and the clinic’s own pages (home and footer, re-read 2026-09-20) publish no 의사면허번호, so the M3 = 3 anchor does not apply. |

| M7 | Advertising honesty One or two soft superlatives or non-absolute safety promises. One soft superlative describing in-house facilities ("최고급"); a "first/only" claim on the same page is attributed to a named government certification and is not scored as an unattributed superlative.

Secondary findings (not scored)
What a professional society, an international directory, a hospital page or another jurisdiction’s register says, shown for information where the country’s own register is closed. These facts enter neither the score nor the coverage.
- M1 · Specialist certification of the responsible physician SECListed in the 대한성형외과학회 (KSPRS) certified-specialist finder as a plastic-surgery specialist (society roster, secondary route); the state specialist-qualification register (lic.mohw.go.kr) is login-gated, so the axis is not scored (v1.3 § C, owner ruling 51).[board] [hira-search] [hira-detail]
What we could not verify
- M1 · Specialist certification of the responsible physician — Register closed to machine queries
- M3 · Basic medical licence — Register closed to machine queries
These cells score nothing and are not negative findings. A cell on a register that is closed to machine queries is left out of the coverage calculation; the others count against it. Each one names why it is empty; an attempt that did not complete is re-run in the next collection pass. If you can point to a public source, send it.
