Founded by the physician and biologist Dr. Max Hotz and born from a philosophy of curative treatment, SOTHYS has a 70-year history of professional skincare treatment. Trained in the field of medical biology, Dr Hotz was motivated to find a remedy to minimize the suffering of burn victims in the aftermath of World War II.

Today, the third generation of the Mas family – Frédéric and Christian Mas – oversee the company. The administrative headquarters, laboratories and production site are located in Brive-la-Gaillarde in the heart of the Corrèze region, while the prestigious address on the Faubourg Saint-Honoré in Paris still represents the beauty salon, just as it has from the beginning.
