Ingredients with a documented concern, from official datasets and our reviewed database.
Sensitive skin: Best avoidedPregnancy: Use with cautionBabies & kids: Best avoidedEczema-prone: Best avoided
- 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.
Oily & acne-prone: High caution
- Pore-clogging:High comedogenicity rating in classic testing.
A close relative of isopropyl myristate with a similar pore-clogging reputation for acne-prone skin.
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.
preservative booster · skin conditioning
Severity 2/10- Irritation:Documented occasional contact allergy and eye irritation.
A preservative booster often paired with phenoxyethanol; low-risk overall with rare reports of contact allergy.
- 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: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.
occlusive · skin protectant
Severity 2/10Editorial- Cancer concern:Concern applies only to unrefined grades containing PAHs; cosmetic grade is highly refined (EU-mandated).
The most effective occlusive known and a staple of eczema care. The cancer concern belongs to unrefined industrial grades — pharmaceutical-grade petrolatum in cosmetics is rigorously purified.
