HomeOur Approach


A brand inspired by ecobiology

Etat Pur embodies perfectly the ecobiological approach principles developed by NAOS (the origin of the Bioderma and the Institut Esthederm brands) for more than 40 years: better preserve your skin’s ecosystem and strengthen its natural mechanisms.

Ultimate respect for the skin and its functioning is our founding principle, reflected both in our concept (two distinct product lines – Pure Care and Pure Active Care) and in our formulation approach.

Respectful, ultra-safe formulation

Our extremely rigorous approach to product formulation goes well beyond common practice in cosmetics – even organic cosmetics. Our formulation charter only includes 300 (just 1%) of the 30,000 ingredients generally used in cosmetics.

Selection of these ingredients takes into account the very latest independent scientific research and publications, to ensure an in-depth knowledge and mastery of their modes of action.

Our positive formulation approach is based on 3 key principles:


We focus on ingredients that are strictly essential for the desired benefit. No unnecessary or useless ingredients to overburden the skin.


Our ingredients are chosen from amongst the purest available (pollutant free). One of the most important selection criteria is to check for potential formol, phthalate, solvent, pesticide or heavy metal residue.


We only use the safest components in order to ensure that our products are safe for all skin types. Above all, we do not use anything that might be harmful or controversial: amongst other things, silicon, mineral oils and synthetic colourants have all been banned from our formulas.

Everyday routine: Pure Skincare

Biomimetic Pure Skincare products contain no active ingredients, giving the skin just what it needs without over-treating it. They are specially designed to get back to basics: cleansing, moisturising and protecting the skin, day in, day out.

Because the skin is better at assimilating the things that most resemble it, we formulate our Pure Skincare using as many biomimetic ingredients as possible, to ensure perfect affinity with the skin. Biomimetic ingredients are either the same as or very similar to the skin’s natural components, resulting in optimum tolerance and efficacy for our products.

Over 98% of the ingredients in our skincare products respect the 4 classes defined in our biomimetic technology, depending on their degree of affinity with the skin.

The index on the front of the packaging rates the level of nutrition (fat) that the product provides. For example, our Light Moisturising Cream has a low index of 2 out of 5, providing the perfect balance of moisture and nutrition for normal to oily skin. This rating will help you make the best choice to match your skin type and its changing needs.

Treating problems when necessary: Pure Actives

Complementing Pure Skincare, the Pure Actives range treats occasional, localised skin problems. Each active is a specific solution to a specific problem.

The molecules in our Pure Actives are selected and dosed based on independent scientific literature to ensure that they are fully effective in treating the problem at hand, without being harsh to the skin.

Our patented IN-SKINTM technology ensures targeted action. This patent improves the skin’s permeability, helping the active ingredient penetrate the skin and work exactly where it’s most needed.

To maintain the efficacy of Pure Actives, we package them in small, anti-UV containers suited to occasional, short-term use. Their unique, one drop at a time system delivers exactly the right dose: 1 pump = 1 x 45 mg (+/-5 mg) drop. It also reduces the risk of microbial contamination.
