- 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
- Irritation:A strong 'sulfate-free' cleanser that can be as stripping as sulfates.
A common 'sulfate-free' marketing substitute that cleans — and can strip — just as aggressively as the sulfates it replaces.
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: Use with caution
- Allergy risk:Named Allergen of the Year 2004; impurities (amidoamine) drive most reactions.
A mild coconut-derived surfactant in countless 'gentle' cleansers. Most allergy is caused by manufacturing impurities, so quality varies by brand.
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.
Sensitive skin: Use with caution
- Allergy risk:EU-declarable fragrance allergen.
A common jasmine-scented ingredient in fine fragrance and skincare, declared as an allergen on EU labels.
- Environmental impact:Synthetic polymer counted as a microplastic under the EU restriction when in particle form.
A common film-forming polymer scrutinized under the EU's microplastics restriction; skin safety itself is well established.
preservative booster · skin conditioning
- Irritation:Documented occasional contact allergy and eye irritation.
A preservative booster often paired with phenoxyethanol; low-risk overall with rare reports of contact allergy.
- Irritation:Can cause transient, non-allergic flushing/stinging on reactive skin.
A food-grade preservative generally regarded as one of the gentler options; occasional non-immune stinging is its main drawback.
