Dipotassium Glycyrrhizate

Low risk

A purified glycyrrhizic-acid salt used as a soothing and skin-conditioning ingredient. Cosmetic safety reviewers concluded that dipotassium glycyrrhizate is safe in current cosmetic use and noted poor dermal absorption. MamaSkin nevertheless applies a cautious low-risk classification for consistency with the existing licorice family because high oral glycyrrhizin exposure has pregnancy-related concerns; this is not a topical contraindication.

Melaleuca Alternifolia Leaf Oil

Low risk

An exact label variant for tea tree essential oil. The SCCS concluded that tea tree oil is safe only in specific defended adult dermal product types and concentrations, excluded aerosolised and sprayable formats, and identified it as a moderate skin sensitiser. MamaSkin therefore classifies it as low risk because safety is formulation- and route-dependent, not because it is a pregnancy contraindication.

Questions about this assessment

Why does COSRX Advanced Snail Mucin Power Sheet Mask have a Low risk rating?

Manual review 2026-07-13: The recorded formula was manually reviewed. This formula contains Dipotassium Glycyrrhizate, Melaleuca Alternifolia Leaf Oil, classified as low risk under MamaSkin's pregnancy-screening policy. This is a cautious classification, not a known pregnancy contraindication; see the highlighted ingredient entry for its rationale and sources. The product score is a stored assessment, not a clinical safety guarantee.

Is the licorice-derived ingredient the same as drinking licorice tea?

No. The recorded formula lists a licorice-derived cosmetic ingredient, not an oral licorice product. Different ingredients and routes of exposure should not be treated as interchangeable. Use the exact ingredient's rating and evidence below, together with any manual-review note; this score does not assess teas, supplements or other licorice formulas.

Has every ingredient in COSRX Advanced Snail Mucin Power Sheet Mask been assessed?

19 of 19 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 COSRX Advanced Snail Mucin Power Sheet Mask?

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.
