The Smoothline team of doctors
Highly qualified, experienced experts

Smoothline was founded in 2007 by Dr. Snozzi and other founding partners, who established the first clinic in Switzerland to specialise exclusively in wrinkle treatment with fillers and botulinum.

All treatments at Smoothline are performed by a qualified and experienced team of doctors. All our doctors are experts in their field and members of the Swiss Medical Association (FMH) and certified members of the German Association for Aesthetic Botulinum Therapy (DGBT). They have all the important certifications in the latest techniques of botulinum and filler treatment. Regular advanced training at national and international congresses ensures that the knowledge and skills of Smoothline doctors are always up-to-date. Some of our Smoothline doctors are also involved as consultants and instructors in the training of other doctors.

Smoothline is a member of the "Verband Schweizer Zentren für Ästhetische Medizin" (VSZAM).
