How we assess productsThe recorded formula, with evidence behind each rating. Unmatched ingredients are marked Not assessed in grey.
An animal-derived protein, peptide or secretion filtrate used for hydration and skin conditioning. These large components are expected to have low systemic absorption through intact skin. No pregnancy-specific hazard signal was identified for normal topical cosmetic use. Cosmetic-grade materials should be processed to control microorganisms, infectious agents and source-derived impurities, and protein allergy remains possible.

A sugar, starch, inulin or cellulose derivative used for emulsification, film formation, absorbency or formula texture. These carbohydrate-based materials are not expected to produce meaningful systemic exposure through intact skin, and related cosmetic safety assessments do not identify a reproductive or developmental hazard for normal use. Fine dry powder should not be deliberately inhaled.

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. Niacinamide appears in the recorded formula, but its individual rating applies to that ingredient, not automatically to the whole product. Check the other ingredient ratings, any grey Not assessed entries and the stored product assessment. A niacinamide percentage or a product name is not a substitute for checking the full list.

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.
