MamaSkin currently classifies La Roche-Posay Serozinc as No known risks, with a stored score of 100/100. This is MamaSkin’s screening classification for the recorded formula, not a guarantee that the finished product is safe for every pregnancy.
No higher-risk ingredient flags are shown in this recorded breakdown. An ingredient without a matched assessment can still display the default No known risks label; that default is not evidence of a completed safety review.
3 of 3 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.
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.
