Jean-Noël Thorel, founder of NAOS, disrupted the establishment’s understanding of the beauty industry with his vision. He has always seen the skin as a living ecosystem that constantly interacts with its environment and that changes over time.

This dynamic vision gave birth to NAOS scientific approach : Ecobiology, the contraction of “ecosystem” & “biology”. It is the art of preserving the skin’s ecosystem by strengthening its natural mechanisms.

Radically different from traditional cosmetics, Ecobiology is based on respect for the skin and knowledge of its biology.

Rather than over-treating the skin, it must be taught how to function properly…


Born from and rooted in this ecobiological approach, Bioderma, Institut Esthederm and Etat Pur are 3 brands inspired by NAOS philosophy and all share the same scientific and human requirements.


For over 40 years, we have launched disruptive innovations and have registered more than 70 patents. The relationships we have built with different communities (healthcare, beauty and well-being professionals as well as our users) help feed our capacity for innovation.
Here are some of the world-known innovations created by NAOS
