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 Found, status current; the registered specialty is adjacent to what is advertised — a closed list: plastic and reconstructive surgery, dermatology, maxillofacial surgery, facial ENT, oculoplastic ophthalmology, general surgery, aesthetic or cosmetic medicine where it is a recognised specialty. GMC Specialist Register: plastic surgery, entry from 11 Jul 2000, matching the clinic's plastic surgery focus. The GMC record is held as "Ioannis Alexandridis"; the clinic's own site spells the surname "Alexandrides" and the first name as the Greek short form "Yannis" — first name, specialty and registration period are otherwise consistent with the clinic's own biography of its founder.

| M2 | Identifiability of the responsible physician Physician(s) named with role and tied to this address. |
SEC | 16 | 2026-08-31 | |
| M3 | Basic medical licence Matched by name (surname stem and given name or initial; a second identifier where the name is ambiguous). Matched by name (with the spelling variant above); the clinic does not publish a GMC number. [gmc-alexandridis] |
OFF | 8 | 2026-08-31 | |

OFF | 10 | 2026-08-31 | |
| M5 | Legal-entity traceability Only a brand, without a legal form and without a responsible person. Whatever we find ourselves is shown on the profile as a fact and does not raise this cell. |
OFF | 8 | 2026-09-22 | |
| M6 | Self-disclosure of identifiers Logos without numbers. Qualifications and board memberships are named (American Board of Plastic Surgery, UK GMC Specialist Register, European Board of Plastic Surgery); no GMC, CQC or company registration numbers are published. [site] |
SEC | 10 | 2026-08-31 | |
| M7 | Advertising honesty One or two soft superlatives or non-absolute safety promises. One or two soft superlatives (“Award-Winning cosmetic clinic”, “world-renowned”) without an outcome or safety guarantee. [site] |
SEC | 12 | 2026-08-31 | |
| M8 | Cross-locale consistency Could not verify — no points, counts against coverage, not a negative finding. Reason: Single language front. Last attempt: clinic_site, 17 September 2026 — one language front; no hreflang alternates or language links The clinic site publishes one language front; nothing to compare. |
? | ? | 5 | 2026-08-31 |

Score ceilings
No ceiling applies. We never apply one on 'not found' alone.
Holds
No hold on this profile.
Inclusion policy
Four mechanical conditions. The first three decide whether a clinic is listed at all; the fourth decides whether it can be scored.
| Identifiable: live public surface + working in-country contact | verified yes [site] |
|---|---|
| Provides the service itself (not an aggregator, booking site or tour packager) | verified yes [site] |
| In scope: the intervention is performed by a physician | verified yes [site] |
| Names a responsible physician | verified yes [site] |
Who is responsible
Named physicians and the legal entity, as published and as matched in the registers. A missing number is a statement about disclosure, not about licensing.
| Physician | Role | Register ID |

Scope and procedure segments
Clinic focus: specialist (no focus adjustment) [site]
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.
What we could not verify
- M8 · Cross-locale consistency — Single language front
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.
