Questions about this assessment
Why does Mustela Stretch Marks Cream have a No known risks rating?
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.
Has every ingredient in Mustela Stretch Marks Cream been assessed?
25 of 25 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.
Does this assessment apply to my Mustela Stretch Marks Cream?
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.
Does this pregnancy assessment also establish breastfeeding suitability?
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.
