Endocrine disruptors and allergens: two invisible but very different threats

In the world of beauty, some threats lurk in our bottles with surprising subtlety. Endocrine disruptors and allergens are among these invisible intruders, capable of disrupting our hormonal balance or triggering our immune system. Their names often come up in discussions about health and cosmetics, but their mechanisms, impacts, and ways to protect ourselves from them remain unclear to many of us.

How can we tell the difference between these two silent enemies? What dangers do they pose to our bodies, and how can we avoid them without sacrificing our beauty routines? Let's explore this world together, where vigilance and harmony intertwine.

What is an endocrine disruptor?

According to the WHO (World Health Organization), an endocrine disruptor is a substance foreign to the body, or a mixture of substances, capable of disrupting one or more functions of our hormonal system. They have numerous harmful effects on health, sometimes even on future generations. They are found everywhere: furniture, textiles, paint, food, certain medications, perfumes, beauty products… In cosmetics, these intruders are found in various compounds: pesticides, plasticizers, industrial pollutants… so many sources that infiltrate our daily lives without our knowledge, and accumulate.

Faced with these risks, regulations concerning endocrine disruptors have been strengthened. However, in our view, they remain insufficient because they do not take sufficient proactive measures regarding substances of concern or those strongly suspected of affecting our hormonal balance.

To learn more, check out our article on the most demanding labels regarding endocrine disruptors, which go beyond regulations.

What is an allergen?

An allergen is a substance capable of triggering a disproportionate immune system reaction in some people. Reactions to cosmetic products often result in eczema, redness, hives, or itching, and can even lead to respiratory problems such as asthma.

No product is completely risk-free, regardless of its origin: pharmacy, organic store, or supermarket. Even natural formulas can contain allergens, because the absence of chemicals does not mean the absence of a possible reaction.

Ingredients often implicated include preservatives, emulsifiers, certain perfumes and their fixatives, as well as formaldehyde present in nail polishes.

In perfumery, natural molecules such as lavender, cinnamon, and thyme, as well as their synthetic equivalents (citronellol, benzyl salicylate), are among the most common allergens. In sensitive skin, simple contact is sometimes enough to trigger a skin reaction, which is exacerbated in some cases by sun exposure.

Endocrine disruptors vs. allergens: the key differences to remember

Endocrine disruptors and allergens are often confused because they are found in the same products. However, their effects, mechanisms, and onset of action are completely different.

Endocrine disruptors Allergens
Targeted system Hormonal system Immune system
Mode of action Mimics, blocks, or disrupts the action of hormones Triggers an excessive immune response
Effects Long-term impact on: fertility, growth, puberty, hormone-dependent risks Immediate side effects: eczema, redness, itching, asthma
Vulnerable populations Pregnant women, babies, children People with allergies or sensitivities
Presence in cosmetics Preservatives, UV filters, plasticizers Essential oils, perfumes, fixatives

Why are they confused?

Because they coexist in the same universes: creams, perfumes, shampoos… A product can contain both allergenic molecules (from essential oils) and endocrine disruptors (like certain preservatives).

Are they present in the same products?

Yes, but not for the same reasons. Endocrine disruptors mainly come from chemical substances used for stabilization, filtering, or preservation. Allergens, on the other hand, are primarily linked to perfumes and aromatic compounds, whether natural or synthetic.

How to spot them and protect yourself from them?

1. Learn to read labels

To avoid these unwanted ingredients, you must first learn to decipher the INCI list , the international nomenclature that reveals the true composition of cosmetics. It becomes your best ally for identifying risky ingredients. Certain names should raise red flags: parabens, benzophenone, and triclosan for endocrine disruptors; limonene, geraniol, and linalool for allergens.

2. Use decryption apps

Tools like Yuka or INCI Beauty let you scan your products and quickly identify potentially harmful ingredients. It's a simple way to make better choices without spending hours deciphering labels. These apps also provide clear explanations, rate products, and sometimes suggest healthier alternatives.

While using these apps has become a very useful daily habit, maintain a critical eye on the components they sometimes highlight. Indeed, although they prove particularly useful for detecting harmful chemicals, they don't differentiate between the origin of certain substances, whether natural or petrochemical.

For example, a 100% natural perfume might receive a lower rating due to the presence of naturally occurring allergens in the essential oils used in its creation. Indeed, some of these essential oils are classified as "labelable allergens," such as limonene or geraniol. They lower the rating, but not the quality!

Our advice:

Don't rely solely on the rating, but rather look at the type of products being promoted.

You can do this by clicking on the small ℹ️ icon next to the component name to learn more about the issue it represents.

If the product contains endocrine disruptors (even if they are potential), pollutants, or even potential carcinogens, put it back.

On the other hand, if you only detect allergens, you can delve deeper into the product and brand to discover the origin of these allergens and reassure yourself - or not! - about the safe use of this product.

3. Opt for transparent brands

Opt for brands that create natural skincare products without endocrine disruptors , designed with ingredients chosen for their safety and purity.

At Aimée de Mars, every fragrance and every skincare product reflects a deep respect for the body and the planet, because the effects of endocrine disruptors on the environment are as concerning as their impact on our health.

4. Trust your skin and your feelings

While endocrine disruptors have long-term effects on our body and therefore do not cause immediate effects upon contact, allergens provide clues that should not be ignored.

Irritation after applying a product? Recurring itching? Your body is trying to tell you something. Even natural ingredients can trigger allergic reactions. Always test a new product on a small area before using it permanently. Also, observe the reactions over time: some effects appear after several uses. If a product causes persistent discomfort, stop using it immediately and opt for minimalist formulas specifically designed for sensitive skin.

Your comfort is the best indication of what truly suits you.

Responsible beauty to enhance the body and preserve nature

When beauty is accompanied by healthy and transparent formulas, it regains its essential role: to offer us pleasure and serenity.

Every conscious choice transforms our routines into balanced rituals, where respect for the body and the planet go hand in hand. Because responsible beauty can be elegant, kind, and deeply soothing.
