Ingredients with a documented concern, from official datasets and our reviewed database.

- Hormone disruption:Classified as toxic to reproduction (CMR 1B); banned in the EU since March 2022.
- Allergy risk:Well-documented fragrance sensitizer.
The lily-of-the-valley scent 'Lilial', banned in EU cosmetics in 2022 after being classified as presumed toxic to human reproduction. Still legal in some other markets — check older or imported products.
Sensitive skin: High cautionEczema-prone: Best avoided
- Allergy risk:Among the most potent of the EU-declarable fragrance allergens.
A carnation-type scent chemical and one of the strongest sensitizers among declared fragrance allergens; industry limits its use concentration.

- Allergy risk:Fragrance is the single most common cause of cosmetic contact allergy.
- Irritation:Frequent trigger of stinging and redness on reactive skin.
Caredermis curated dermatological review
An umbrella term that can hide dozens of undisclosed scent chemicals. Fragrance is the leading cause of allergic contact dermatitis from cosmetics, and dermatologists routinely advise fragrance-free products for eczema, babies and sensitive skin.
Sensitive skin: Use with cautionEczema-prone: High caution
- Allergy risk:EU-declarable allergen; oxidized linalool is a common patch-test positive.
A floral scent molecule found in lavender and many essential oils. It oxidizes on air exposure into strongly sensitizing compounds, which is why it must be declared on EU labels.
Sensitive skin: Use with cautionEczema-prone: High caution
- Allergy risk:EU-declarable allergen; oxidation products are potent sensitizers.
The citrus-peel scent molecule. Like linalool, it becomes allergenic mainly after oxidizing in opened products.
Sensitive skin: Use with cautionEczema-prone: High caution
- Allergy risk:American Contact Dermatitis Society Allergen of the Year 2018.
- Irritation:Can irritate compromised skin at higher concentrations.
A workhorse humectant and penetration enhancer that is fine for most, but a recurring culprit in eczema patients' patch tests.
Babies & kids: Use with caution
- Irritation:Occasional stinging and irritation, mostly around eyes and on damaged skin.
Today's most common preservative, considered safe by the SCCS up to 1%. French authorities advise avoiding it in wipes and diaper-area products for children under 3 as a precaution.
Oily & acne-prone: Use with caution
- Pore-clogging:Cosmetic grade is minimally comedogenic despite its reputation.
Highly refined mineral oil is an inert, non-sensitizing emollient. Its bad reputation comes from industrial-grade oils that are never permitted in cosmetics.
Pregnancy: Use with cautionBabies & kids: Use with caution
A longer-chain paraben with measurable (though weak) estrogenic activity, prompting the EU to reduce its allowed concentration and Denmark to ban it in products for children under 3.
Pregnancy: Use with cautionBabies & kids: Use with caution
The paraben with the strongest endocrine signal in laboratory studies; the EU restricts it and bans it in leave-on diaper-area products for young children.
- Irritation:Above ~10% it becomes keratolytic and can sting on broken skin.
A natural moisturizing factor: hydrating below 10%, callus-softening above. Valuable in eczema care despite stinging on open skin.
- Environmental impact:Classified vPvB (very persistent, very bioaccumulative); EU restricts it in cosmetics from 2027.
Caredermis curated dermatological review
A volatile silicone giving that silky slip, now being phased down in the EU because it persists and accumulates in aquatic ecosystems.
- Environmental impact:Not biodegradable; accumulates in the environment via wash-off.
The workhorse silicone — inert and non-sensitizing on skin (even FDA-approved as a skin protectant), with persistence in the environment as its main criticism.
- Environmental impact:Persistent silicone, like dimethicone.
A silicone gum for silky slip; skin-inert with the family's usual environmental-persistence criticism.
- Environmental impact:Poorly biodegradable; can remobilize heavy metals in waterways.
A metal-binding stabilizer that is safe on skin at the tiny amounts used; its criticism is environmental persistence.
