About Institut Jean-Marc Guichet / Leg Lengthening Clinic
The Institut Jean-Marc Guichet, also branded Leg Lengthening Clinic, is a cosmetic height-increase practice associated with Centre Phocéa at 14 Bd Gustave Ganay in Marseille. Jean-Marc Guichet, Orthopaedic surgeon (>30 yrs) and inventor of the Albizzia Nail (1987) and Guichet Nail (2009), splits his activity between Marseille, Milan (Columbus Clinic) and Princess Grace Hospital in London. Methods on record are the Guichet and Albizzia nails; the Guichet Nail is implanted only at his own clinics.
The public record is limited, and editors note he now practises mainly in London and Milan rather than France. The record flags heavy self-promotion, including a Marquis Who's Who press release and dedicated marketing domains, so treat promotional claims with caution. No official email or phone was found on reviewed pages, no price is published, and no accreditation is listed. Google shows 4.2 from 31 reviews. Consultations are offered in Italian, English and French.
CURRENT and real: confirmed via patient community (limblengtheningforum), biography mirrors, YouTube surgery footage, and multiple third-party references, plus his own sites (supporting only). ADVERSARIAL FLAG: heavily self-promoted (Marquis Who's Who press release, dedicated marketing domains) — the archetypal marketing-forward cosmetic operator this niche is known for; treat promotional claims cautiously. No official email/phone published on reviewed pages — NOT guessed. Price is aggregator-sourced, indicative only.
