Etat Pur

Unique Ecobiological approach

“Instead of treating the skin, we need to teach it how to live.”
Jean-Noël THOREL, pharmacist and founder of NAOS (Bioderma, Institut Esthederm & Etat Pur)

A science. A philosophy. A revolution.  

 

Pioneered by NAOS, Ecobiology views the skin as an intelligent, self-regulating ECOsystem. Rather than simply correcting visible signs or overtreating, we work in harmony with skin BIOLOGY to support its natural mechanisms and address root causes for long-lasting, respectful efficacy. This is what we call Ecobiology - conscious, respectful science inspired by skin itself - and it has been guiding every NAOS formula for over 40 years.

Say no to over treatment

At Etat Pur, we believe the biggest threat to skin is overtreatment: too many ingredients, promises and pressure. 
We do things differently: we give skin only what it truly needs to function at its best. Nothing more. Nothing less.

 

 

Etat Pur: Skin diversity truly respected

 

Each skin is unique: type, age, tone, origin...

Our ecobiological approach respects this diversity with tailored solutions that avoid overtreatment and support skin’s natural balance.
We offer Pure Biomimetic Skincare with different textures and hydration levels, and Pure Actives each targeting a different concern, to answer every skin needs.

 

Science, with a conscience

 

Ecobiology means conscious formulation with deep skin respect. At Etat Pur, we choose ingredients for their biological relevance, not trends.
We have rigorously selected 150 ingredients - less than 0.5% of cosmetic ones - for their purity, safety, proven efficacy and usefulness. Hence our fragrance-free formulas, since your skin doesn’t need it. We ensure full transparency to build trust and support skin health, lastingly.
