The integration of essential oils, powerful natural ingredients, involves strict formulation control, incorporated from the earliest stages of development.

Safety is a fundamental pillar of the performance of Decléor skincare products.

Before being marketed, Decléor skincare products undergo:

• a comprehensive safety assessment of the finished product,
• dermatological tests conducted on volunteers.

Some products are also tested on sensitive skin, depending on their formula and cosmetic use.

Tests are carried out on the final formulas, as they are used by the consumer.

Essential oils are powerful active ingredients that require precise and controlled dosing.

At Decléor:

• they are never used pure,
• their concentration is defined based on their biochemical profile and cosmetic use,
• their integration into the formula aims for an optimal balance between efficacy and tolerance.

Effectiveness depends on the right dose, not on overconcentration.

Certain naturally occurring molecules in essential oils must be listed in the INCI list when their concentration exceeds thresholds defined by European regulations.

At Decléor:

• these mentions guarantee clear and transparent information,
• formulas are evaluated as a whole, on the finished product,
• skin tolerance is systematically taken into account during development.

The presence of allergens listed in the INCI is a regulatory requirement and does not in itself indicate a hazard.

To date, essential oils are not classified as endocrine disruptors under European regulations.

As with any cosmetic ingredient, the assessment is based on:

• the nature of the molecules,
• their concentration,
• the route and frequency of exposure.

Each Decléor formula undergoes a comprehensive safety assessment in accordance with European cosmetic regulations.

Decléor products are designed for safe and controlled cosmetic use under normal conditions.

Some experimental studies or isolated clinical observations have explored the hormonal activity of certain essential oils under conditions far removed from regulated cosmetic use.

These data are taken into account in the safety assessment, which is based on the consumer’s actual exposure.

Decléor is committed to a dynamic of continuous improvement of its formulas.

While some current formulas follow a historical continuity, the brand continues in-depth work on its formulation standards to support the evolution of:

• scientific knowledge,
• regulatory requirements,
• and consumer expectations.

Safety, tolerance, and effectiveness remain the absolute priorities of this approach.

Decléor applies the cosmetovigilance obligations provided by European regulations.

In case of a reaction or discomfort with a product, it is recommended to:

• stop using it,
• rinse the affected area,
• contact the Decléor consumer service for appropriate support.

Safety extends beyond formulation, through attentive listening and follow-up.

Decléor skincare safety is based on:

• a rigorous cosmetic formulation,
• dermatological tests on volunteers,
• a precise mastery of essential oils,
• complete regulatory transparency,
• a responsible approach, constantly evolving.
