- 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: High cautionEczema-prone: Best avoided
- Allergy risk:Potent EU-declarable allergen; the cinnamon scent molecule.
- Irritation:Can cause immediate stinging and flushing.
The cinnamon scent molecule, a strong sensitizer and irritant that appears in fragrance blends and lip products.
Sensitive skin: Use with cautionDry skin: Use with cautionEczema-prone: High caution
- Irritation:Drying when high on the ingredient list; negligible in trace amounts.
Plain ethanol — position on the label matters: near the top it is drying; near the bottom it is a harmless solvent trace.
Sensitive skin: Use with cautionEczema-prone: High caution
- Allergy risk:EU-declarable allergen; lemon-scented sensitizer.
The lemon-scent molecule in lemongrass and citrus oils, a recognized contact allergen requiring EU label declaration.
Sensitive skin: Use with cautionEczema-prone: High caution
- Allergy risk:EU-declarable allergen with well-documented sensitization.
A rose/geranium scent molecule and one of the more frequently positive fragrance allergens in patch testing.
Sensitive skin: Use with cautionEczema-prone: High caution
- Allergy risk:EU-declarable allergen; use concentrations limited by industry standards.
A synthetic lily-of-the-valley scent and well-documented contact allergen.
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: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 caution
- Allergy risk:EU-declarable fragrance allergen.
A violet-type scent chemical requiring EU allergen declaration.
Sensitive skin: Use with cautionEczema-prone: Use with caution
- Allergy risk:EU-declarable fragrance allergen.
A rose-type scent component on the EU's mandatory-declaration allergen list.
Sensitive skin: Use with cautionEczema-prone: Use with caution
- Allergy risk:EU-declarable allergen found in tonka bean and many perfumes.
A sweet hay-scented molecule requiring EU allergen declaration; a regular positive in fragrance patch-test series.
- 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.

Severity 7/10Editorial- Environmental impact:Classic microplastic; plastic microbeads banned in many countries; EU microplastics restriction phasing it out.
Caredermis curated dermatological review
The plastic behind the microbead scandal — banned as a rinse-off scrub ingredient across many jurisdictions and being phased out of cosmetics under the EU microplastics restriction.
- 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.
