Pregnancy · Ingredient check
Paste any product's ingredient list. We flag what dermatology guidance says to avoid or use with caution during pregnancy, what's generally considered fine — and we cite every call. This is an educational screen, not medical advice.
We match each ingredient on your label against a small, hand-curated rule set drawn from peer-reviewed reviews and dermatology-authority guidance (ACOG-aligned MotherToBaby fact sheets, Canadian Family Physician, and journal reviews — every flag links its source). Matching is literal substring matching on ingredient names, so a rule fires only when a known token is present. We grade each flag's evidence honestly: 'strong' means human/regulatory consensus, 'limited' means the basis is mechanistic or simply an absence of a safety signal.
This tool is conservative but imperfect. It can miss ingredients we don't have a rule for (an unflagged ingredient is NOT a guarantee of safety — it may just be unstudied), and it cannot see concentration, which changes the answer for dose-dependent ingredients like salicylic acid and AHAs. Much of the 'safe' evidence is reassurance-by-absence, not a dedicated pregnancy trial. It does not account for your medical history, trimester, or a product's full formulation.
