The founder
“Our focus: skin that stays good for the long term.”
As a physician, Dr. med. Rosemarie Klotz was looking for skincare for her patients with effective concentrations and without unnecessary fillers. When she could not find it, she developed it herself. Today we make all our products in our own manufactory in Germany.
