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

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

Before their market launch, Decléor 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.

The tests are conducted on the final formulas, as they are used by the consumer.

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

At Decléor:

• they are never used pure,
• their concentration is defined based on 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 right 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 mentions guarantee clear and transparent information,
• the formulas are evaluated in their entirety, on the finished product,
• skin tolerance is systematically taken into account during development.

The presence of allergens listed in the INCI meets 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 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 the European Cosmetic Regulation.

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

Some experimental studies or isolated clinical observations have explored the hormonal activity of certain essential oils, in conditions very different 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 dynamic of continuous improvement of its formulas.

If some current formulas are part of a historical continuity, the brand continues to work on its formulation standards to support evolution:

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

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

Decléor applies the obligations of cosmetic vigilance as required 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 the formulation, through attentive listening and follow-up.

The safety of Decléor treatments 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.
