He began his career in a pharmacy located in the Gare de l’Est train station in Paris, working in close contact with clients. This experience was the basis
of his determination to better understand the needs of all and to address them differently.

In 1973, he worked alongside Jean-Henri Belin the Managing Director of the PHARMEX pharmaceutical laboratory, which belonged to MERCK and RICKER. He then became the Director of GOUPIL laboratories alongside its founder, Jean-Jacques Goupil. He left due to an ethical disagreement over the formulation of his sun care products.

Jean-Noël Thorel’s pioneering vision naturally led him to entrepreneurship. In 1977, Jean-Noël Thorel founded CEREDAP (Centre d’Etudes et de Recherche en Esthétique et Dermatologie Appliquée) the research center, where he created the first Bioderma and Institut Esthederm products.

Starting from the principle that « When skin is suffering, rather than over-treat it, it must be taught to function properly », he created innovative product concepts
with the support of renowned dermatology and biology researchers and registered
his first patents.

With the creation of new modes of action inspired by the skin and passing trough the skin barrier, he contributed to regulatory changes and changed the paradigm
of traditional cosmetics in the Skincare field.
