MamaSkin currently classifies BYOMA Phyto Mucin Glow Serum as Low risk, with a stored score of 79/100. This is a precautionary classification, not an unqualified pregnancy-safe recommendation. Read the ingredient context and any manual-review explanation below.
The recorded formula includes 1 ingredient entry with a risk flag: Lactic Acid (Low risk). These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail.
38 of 38 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.

Formulations can change without notice. For the most accurate result, compare this list with your packaging and scan the exact ingredient label in MamaSkin when you repurchase.
38 of 38 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.
