MamaSkin currently classifies COSRX Advanced Snail 96 Mucin Power Essence as Low risk, with a stored score of 76/100. 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 2 ingredient entries with risk flags: Phenoxyethanol (Low risk), Ethyl Hexanediol (Low risk). These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail.
12 of 12 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.

Phenoxyethanol is a preservative permitted in EU cosmetics up to 1.0%. The SCCS concluded it is safe for cosmetic use at that level, including when considering higher cosmetic exposure scenarios in infants and young children. Main practical concern is irritation/stinging on very sensitive or compromised skin rather than a pregnancy- or breastfeeding-specific risk.

Ethyl Hexanediol is an aliphatic alcohol used mainly as a cosmetic solvent. It can be absorbed through skin. Animal studies reported developmental effects after high oral and dermal doses, but those effects occurred at doses that also caused substantial maternal toxicity. CIR concluded that the ingredient is safe as cosmetically used and later reaffirmed that conclusion. MamaSkin nevertheless classifies it as low risk under its precautionary pregnancy-screening policy; this is not a known human pregnancy contraindication at normal cosmetic exposure.

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.

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.
12 of 12 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.
