Stick lèvres Nacré — ingredient safety report

• Allergy risk:Fragrance is the single most common cause of cosmetic contact allergy.
• Irritation:Frequent trigger of stinging and redness on reactive skin.

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.

• 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.

• Cancer concern:IARC 2B by inhalation only — relevant to loose powders and sprays, not creams.

A mineral UV filter and pigment that is one of the safest sunscreen choices in cream form; the inhalation-based cancer classification only matters for powder and spray formats.

• Environmental impact:Classic microplastic; plastic microbeads banned in many countries; EU microplastics restriction phasing it out.

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: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.
