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

Safety is a fundamental pillar of Decléor's healthcare performance.

Before being launched on the market, Decléor skincare products undergo:

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

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

The tests are carried out on the final formulas , as used by the consumer.

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

At Decléor:

• They are never used in their pure form .
• Their concentration is defined according to their biochemical profile and their cosmetic use.
• Their integration into the formula aims for an optimal balance between efficacy and tolerance .

Effectiveness depends on the correct dose, not on overconcentration.

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

At Decléor:

• These statements guarantee clear and transparent information .
• The formulas are evaluated as a whole, based 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 constitute an indicator of danger.

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

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

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

Each Decléor formula undergoes a complete safety assessment , in accordance with the European Cosmetics Regulation.

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

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

This data is taken into account in the safety assessment, which is based on the actual exposure of the consumer.

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

While some current formulas are part of a historical continuity, the brand continues to work extensively on its formulation standards, in order to keep pace with evolution:

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

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

Decléor applies the cosmetovigilance obligations stipulated by European regulations.

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

• discontinue use,
• rinse the affected area,
• Contact Decléor customer service for tailored support.

Security extends beyond mere wording, through careful listening and follow-up.

Decléor's patient 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.
