Ingredient ratings refreshed 1 October 2026. Formulas vary by market and can change. Always compare with your packaging.
No higher-risk ingredient flags are shown in the assessed entries. Ingredients without a matched rating are marked Not assessed, not No known risks. The product score is a stored assessment, not a clinical safety guarantee.
No. This recorded formula contains Panthenol or Madecassoside, but a barrier-care claim does not establish the assessment of all its other ingredients. Read the individual ingredient evidence and any manual-review explanation, and compare the recorded list with your packaging.
26 of 26 ingredient entries on this page have a recorded score, evidence summary and source text. That describes documentation coverage, not proof that the finished formula has been clinically tested during pregnancy.
Only if the ingredient list on your packaging matches the recorded formula shown here. Formulas can differ by market and change over time. Compare the full list, not just the product name; report a mismatch if it differs.
No. This page presents a pregnancy-focused product assessment. Do not infer a breastfeeding conclusion from its score or label; breastfeeding requires a separate assessment of the formula and how it is used.
