Endocrine disruptor

An endocrine disruptor is a substance that can interfere with the hormonal system by mimicking, blocking, or modifying the action of natural hormones. This disruption can affect growth, reproduction, metabolism, or the immune system.

The European Cosmetics Regulation prohibits the use of substances classified as proven endocrine disruptors, except where a scientifically justified exemption is granted. The EU is gradually assessing suspected ingredients, but some remain permitted pending stronger evidence.

A proven endocrine disruptor has been clearly identified by human or animal studies. A presumed endocrine disruptor is based on strong but still 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 hormonal effects. Thus, the “natural” label is 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 disorders remains poorly documented.

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

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

Indeed, children are regarded as more susceptible to hormonal disturbances, which underscores the need for heightened vigilance.

Prioritize short formulations and avoid using multiple products to limit exposure to cosmetic endocrine disruptors.
