Hypoallergenic – meaning, labeling & skin compatibility

What does "hypoallergenic" mean?

The term hypoallergenic refers to products designed to pose a lower risk of allergic reactions. Literally translated, it means "less allergenic." In skincare, this label refers to formulations developed without known allergenic ingredients—such as certain fragrances, preservatives, or dyes. ^¹

Not a legally protected designation

In the European Union, “hypoallergenic” is not a legally defined term . This means that manufacturers may use it if they can demonstrate, through appropriate testing methods, that the product is well tolerated and does not contain common allergens. ^{^2,3}

However, the EU Cosmetics Regulation (Regulation (EC) No 1223/2009) stipulates that cosmetic advertising claims must be true, verifiable, and not misleading . Therefore, the term "hypoallergenic" is also subject to the burden of proof on the manufacturer. ⁴

How are hypoallergenic products tested?

To demonstrate skin compatibility, dermatological tests are carried out, usually under medical supervision. Common procedures include:

• Patch tests: Checking whether ingredients trigger contact allergies.
• Repeated Insult Patch Test (RIPT): Long-term test to determine the cumulative skin reaction.
• In-use tests: Application under everyday conditions with volunteer subjects, often also under the supervision of a dermatologist. ⁵

Typical allergens in cosmetics

Certain ingredients are known to trigger allergic reactions. Hypoallergenic formulations specifically avoid these:

• Fragrances: e.g., Limonene, Linalool, Citral.
• Preservatives: e.g., methylisothiazolinone (MI) or formaldehyde releasers.
• Dyes: Some azo dyes and metal oxides.
• Animal proteins: potentially sensitizing in some natural products.

The EU cosmetics regulation currently lists 26 fragrance ingredients that must be declared, as they are considered common allergens and must be listed on the packaging. ⁶

For whom are hypoallergenic products beneficial?

• For allergy sufferers: especially those with a known allergy to fragrances or preservatives.
• People with atopic dermatitis (eczema): their skin barrier is more sensitive and reacts more strongly to irritants.
• People with sensitive skin: who frequently experience tightness, redness, or burning. ⁷

What “hypoallergenic” does not mean

Even hypoallergenic products cannot completely rule out the possibility of an allergic reaction. Everyone reacts individually, and even mild ingredients can cause irritation in certain people. Therefore ^, a patch test on a small area of ​​skin is always recommended before first use.

Hypoallergenic in natural cosmetics

In modern natural cosmetics, such as those from NATURFACTOR, hypoallergenic formulations are increasingly supported by scientific analyses. This involves avoiding the use of fragrances requiring declaration, while carefully testing natural ingredients for purity and tolerability.

Tips for buying hypoallergenic products

• Look for "dermatologically tested" and "without declarable fragrances" .
• Check the INCI list: the shorter and clearer it is, the easier it is to understand.
• For known allergies, choose products with allergy certificates or seals (e.g. DAAB seal).
• Always test new products on a small scale first.

Conclusion

"Hypoallergenic" does not mean "allergy-free," but rather describes carefully formulated products with low irritant potential. People with sensitive or reactive skin especially benefit from this formulation. It remains important to pay attention to individual tolerance, avoid ingredients requiring declaration, and consult a dermatologist if you have any concerns.
