Concerns raised online typically relate to unrefined/poorly refined mineral oils and dietary mineral oil hydrocarbons, not regulated cosmetic-grade topical use.

Mineral ingredient used as a UV filter and skin protectant in many creams and mineral sunscreens. For typical topical use, systemic absorption is very low and it is generally considered acceptable in pregnancy and breastfeeding. If you prefer a cautious approach, avoid inhaling loose powders or spray formats.

The risk band is the primary conclusion. The score adds detail within that band and should not be used to compare products as if a one-point difference were clinically meaningful.
MamaSkin provides pregnancy-focused information, not medical advice. Your midwife, GP, pharmacist or dermatologist should take priority when your circumstances differ from typical cosmetic use.
