Endocrine disruptor

An endocrine disruptor is a substance capable of interfering with the hormonal system by mimicking, blocking or modifying the action of natural hormones. This disruption can have effects on growth, reproduction, metabolism or even the immune system.

The European Cosmetic Regulation prohibits the use of substances classified as confirmed endocrine disruptors, unless a scientifically justified derogation applies. The EU is progressively evaluating suspected ingredients, but some remain authorised pending more robust evidence.

An established endocrine disruptor has been clearly identified through human or animal studies. A presumed endocrine disruptor is supported by robust yet incomplete evidence. A suspected endocrine disruptor presents warning signals, but the available data are insufficient.

Not necessarily. Some natural ingredients, such as certain essential oils or plant extracts, can also have a hormonal effect. The “natural” label is therefore not a guarantee of endocrine safety.

Indirectly, yes. By disrupting hormones, they can worsen hormonally driven skin conditions, such as acne, or certain imbalances in the skin barrier. However, their precise role in skin diseases remains poorly documented.

Certain families, such as parabens or phthalates, are suspected of being endocrine disruptors.

This claim has no formal regulatory definition. It is often based on the exclusion of certain controversial ingredients.

Indeed, children are considered more susceptible to endocrine disruption, emphasising the need for heightened vigilance.

Opting for concise formulations and avoiding the simultaneous use of multiple products helps to limit exposure to endocrine-disrupting substances in cosmetics.
