The story
In 1972 perfumer Jean-François Laporte and Roland de Saint-Vincent, created a perfume company. Hubert d'Ornano acquired this company in 1976, re-naming it Sisley in reference to the Impressionist painter.
Hubert d'Ornano reorganized the company and focused Sisley's research in phytocosmetology. He relied on the research of chemist Egmont Desperrois for his products. He came up with the idea to use essential oils and active ingredients extracted from plants in the beauty products.
