81 allergens that must now be listed in your cosmetics

Since August 1st, the list of fragrance allergens that the law requires to be individually named on a cosmetic label has increased from 24 to 81. What used to be hidden under the word "parfum" must now be explicitly named when it exceeds a minimum threshold. This directly affects the perfumes, creams, gels, and shampoos you use every morning.

The measure stems from Regulation (EU) 2023/1545, which amends the 2009 European cosmetics regulation. It was approved in July 2023 with a three-year margin for adaptation. That deadline has just passed: on August 1, 2026, the obligation began for all new products placed on the market. Existing stock manufactured before this date can continue to be sold until July 31, 2028. During this time, you will see both types of labels coexisting on the same shelf, and that's perfectly fine: both are legal.

What really changes on the label

The change isn't that these ingredients are new or more dangerous than yesterday. They were already in your perfume. What changes is that you now have the right to know they are there. A fragrance allergen is only declared by its name when it exceeds a very low concentration: 0.001% in products that remain on the skin, such as a cream or perfume, and 0.01% in rinse-off products, such as a gel or shampoo. Below that, "parfum" is still sufficient.

You'll notice the practical consequence when you read the back of the bottle. Names like limonene, linalool, citronellol, geraniol, or coumarin, which you already knew, will now be accompanied by many others. The ingredient list will get longer. According to the AEMPS, the goal is for an allergic person to quickly identify what bothers them, without playing lottery with every new product.

And another thing that needs to be clear: the regulation does not prohibit a single ingredient. It only requires it to be named. Nothing is removed; everything is named. Among the new names you will start seeing are vanillin, menthol, carvone, methyl salicylate, or anethole, as well as entire essential oils such as geranium (Pelargonium graveolens) and patchouli (Pogostemon cablin).

Why this shakes up natural cosmetics

Here's the nuance that hardly anyone mentions. Many of these 81 allergens are not strange laboratory chemicals: they are molecules that naturally occur in essential oils. Limonene is found in orange and lemon peel. Linalool and geraniol are in lavender, rose, or ylang-ylang. Coumarin, in tonka bean. A well-formulated natural cosmetic, loaded with authentic essential oils, will suddenly show a longer list of allergens than a cheap synthetic product.

And that's where the misunderstanding, I fear, will arise. Someone looks at two labels, sees that the natural cosmetic declares twelve allergens and the conventional one only three, and concludes that the natural one is "more aggressive." It's just the opposite. That long list is usually proof that there's real essential oil inside, not a synthetic fragrance designed to dodge the fine print. Transparency seemingly punishes those who have nothing to hide.

Therefore, don't trust the word "hypoallergenic" stamped on the bottle: it's not a regulated term and tells you nothing about your specific allergens. Just because something comes from a plant doesn't make it harmless; citral or eugenol, two of the most common skin sensitizers, are 100% plant-derived. A long label doesn't mean a worse product, but a more honest product. I'd much rather have an INCI that names its twelve fragrance components than one that covers everything with "natural aroma" and leaves you in the dark.

What to do if your skin reacts

If your skin is usually calm and has never given you trouble, this is little more than a label curiosity: carry on as usual. The real change is for those who experience tightness, itching, or redness with certain products. For these people, reading the exact name of what bothers them saves them months of trial and error.

The plan is simple. If you already know you react, identify your two or three specific allergens (a dermatologist can confirm them with a patch test) and memorize them. From there, the label works for you: you look for those names in the INCI and simply discard the product. Forget the claims on the front of the packaging; the truth is in the fine print on the back.

My verdict: transparency yes, fear no

As a pharmacist, I welcome the regulation. That a person with reactive skin can read the exact name of what irritates them is a real improvement, not just a formality. But I ask you one thing: don't read a long list of allergens as an alarm. Read it as information. A declared ingredient is not a dangerous ingredient; it's an ingredient that, in very few people and at high doses, can cause a reaction. If your skin tolerates lavender or citrus well, you don't have to avoid them just because they're now listed.

What I do foresee is marketing hype. As soon as a regulation talks about "allergens," a brand always emerges that claims the "free from" medal and tells you that its fragrance-free formula is purer. It's not. Removing all essential oils to shorten the list doesn't make a product better; it makes it more boring and, sometimes, with more synthetic preservatives to compensate. Mistrust anyone who uses this law to scare you instead of to inform you.

On the Costa del Sol, the issue has an extra edge. Here, skin spends the summer between sun, pool chlorine, and salt water, and by August it's thinner and more reactive than usual. That's precisely when a reaction to a fragrance is more noticeable. So, this is a good time to do what almost no one does: turn the bottle over before buying it and read what's in it. Now, finally, the label tells you everything.
