Ingredients with a documented concern, from official datasets and our reviewed database.
Babies & kids: Best avoided
- Cancer concern:IARC reclassified talc as probably carcinogenic (2A) in 2024; historic asbestos contamination drives concern.
A mineral powder at the center of major litigation and a 2024 IARC upgrade to 'probably carcinogenic'. Regulators specifically warn against powder use on babies (inhalation risk); cornstarch is the standard substitute.
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: 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.
- 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:Skin-safe; the ingredient's controversy is ethical (mining labor), not toxicological.
The shimmer mineral in highlighters and glowy creams; safe on skin, with sourcing ethics being its real controversy.
