The EU Allergenic Substances List

When it comes to skincare and cosmetics, knowing about potential allergenic substances is crucial for consumers who may have sensitive or reactive skin. The European Union (EU) has identified 26 specific allergenic substances that require special attention due to their potential to cause allergic reactions.

It is REALLY IMPORTANT to note that you can be allergic to things outside of this list and you may not be allergic to any of the things in this list, but it is a good starting point if you are reacting to products and you don’t yet know why.

In this blog, we will outline these 26 EU allergenic substances, shedding light on common triggers and helping readers make informed choices about the products they use.

Throughout our store, we identify these allergens in product ingredients lists by marking them in italics.

Common Uses and Prevalence

These allergenic substances are often used in fragrance compositions, essential oils, preservatives, and other ingredients commonly found in skincare and cosmetic products. Fragrances are particularly likely to contain some of these substances, as they contribute to the scent of the product. It's important to note that some products may contain more than one allergenic substance, increasing the risk of an allergic reaction.

Allergic Reactions and Precautions

Allergic contact dermatitis is a delayed hypersensitivity reaction that occurs when the skin comes into contact with allergenic substances. Common symptoms include redness, itching, swelling, and the formation of rashes or blisters. Individuals with a history of skin allergies or sensitive skin should be cautious when using products containing these substances.

If you have any kind of reaction to a product, stop using it immediately. We recommend that you patch test products before applying more fully.

Reading Product Labels

To make informed choices and minimise the risk of allergies, consumers should carefully read product labels. Manufacturers are required to list allergenic substances on the product packaging, allowing consumers to identify potentially problematic ingredients.

Being aware of the 26 EU allergenic substances empowers consumers to make informed choices about their skincare and cosmetic products. By checking product labels and being cautious when using products containing these allergenic substances, individuals can reduce the risk of allergic reactions and enjoy a more comfortable and enjoyable skincare routine.
