« Since we started using natural plant extracts, we were amazed by the incredible world we discovered » HUBERT D’ORNANO At Sisley, we believe in the extraordinary richness of the plant world. In each plant, from the most humble to the most precious, science and technology allow our researchers to discover and extract the active ingredients that are at the heart of our products. While the effectiveness of our products lies in our intimate understanding of the skin, the genius of our formulas lies in the synergy of plant extracts. This unique know-how carried by founders Hubert and Isabelle d’Ornano is based on a family adventure and over 80 years of experience and research.
