Strategy Consultant Internship - Sustainability Advisory - Paris F/H (Sept 2026)

Als Spezialist für Hautbiologie und Hyaluronsäure seit 1978 bieten die FILLMED-Labore Fachärzten für ästhetische Medizin ein umfassendes Sortiment an injizierbaren Produkten und Kosmetika, um das Erscheinungsbild ihrer Patienten zu verbessern.

Als Pionier in der ästhetischen Medizin und Marktführer im Bereich der Hautrevitalisierung verfolgt Fillmed einen ganzheitlichen Ansatz zur Gesichtsverjüngung, insbesondere mit: ART FILLER, ein Hyaluronsäure-Gel zur Korrektur von Falten und zur Wiederherstellung des Volumens, NCTF, eine polyrevitalisierende Lösung zur Verbesserung der Hautqualität, sowie die Kosmetiklinie SKIN PERFUSION, die eine personalisierte und tägliche Ergänzung zu ästhetischen Behandlungen ermöglicht.

Fillmed setzt sich zudem für eine verantwortungsbewusstere Schönheitspflege ein. Indem wir Frauen (und Männer!) dabei begleiten, „gut zu altern“, indem wir respektieren, wer sie sind, was sie werden wollen, und ihnen helfen, wieder zu sich selbst zu finden. Die Einzigartigkeit jedes Einzelnen zu feiern, Selbstvertrauen und Selbstwertgefühl zurückzugewinnen – auch das ist die Aufgabe der ästhetischen Medizin. Dieses Engagement zeigt sich in Europa insbesondere durch die Unterstützung von Vereinigungen, die Frauen helfen, nach schwierigen Ereignissen (Arbeitsverlust, Krebs) wieder auf die Beine zu kommen.

Dank einer nachhaltigen internationalen Expansion verfügt das Labor über 9 Tochtergesellschaften (Frankreich, Spanien, Portugal, Italien, Großbritannien, Polen, Belgien, Türkei und China) und exportiert seine Produkte in mehr als 60 Länder, wobei das Wachstum in Asien besonders stark ist.
