Is it suitable during pregnancy?
MamaSkin rates the recorded formula for Laneige Water Sleeping Mask as Low risk (75/100). Review the ingredient context and any manual-review explanation before deciding.
Why this rating?
The recorded formula includes 3 ingredient entries with risk flags: Methyl Trimethicone (Low risk), PCA Dimethicone (Low risk), Parfum (Low risk). These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail.
33 of 34 ingredient entries on this page have a recorded score, evidence summary and source text. 1 entry does not have all of those fields. Unmatched or unrated entries are marked Not assessed in grey; missing evidence does not establish safety.

Ingredient ratings and evidence
Higher-risk flags first. Open an ingredient for evidence.
Parfum
Low risk
Umbrella term for an undisclosed fragrance blend. It’s not usually a pregnancy-specific concern at normal cosmetic use levels, but the exact components and concentrations aren’t fully disclosed on the label, so we score it more conservatively. If you prefer maximum transparency (or you’re sensitive to fragrance compounds), choose fragrance-free/unscented products.

Methyl Trimethicone
Low risk
A lightweight volatile linear silicone used as a solvent and texture ingredient. Related linear methicone ingredients have reassuring cosmetic safety assessments, but an exact final Cosmetic Ingredient Review finding for Methyl Trimethicone was not located. MamaSkin classifies it as low risk because exact-ingredient pregnancy and inhalation data are limited, while no specific pregnancy contraindication has been identified for normal topical cosmetic use.

PCA Dimethicone
Low risk
This ingredient is a silicone polymer documented within CIR's broader dimethicone and substituted-methicone family assessment. CIR concluded the reviewed ingredients safe as used when formulated to be non-irritating to skin and eyes. This is family-level cosmetic evidence, not ingredient-specific human pregnancy evidence for every derivative. MamaSkin therefore retains Low Risk without claiming negligible absorption for this individual ingredient.

Inulin Lauryl Carbamate
No known risks
A sugar, starch, inulin or cellulose derivative used for emulsification, film formation, absorbency or formula texture. These carbohydrate-based materials are not expected to produce meaningful systemic exposure through intact skin, and related cosmetic safety assessments do not identify a reproductive or developmental hazard for normal use. Fine dry powder should not be deliberately inhaled.

Hydroxypropyl Bispalmitamide Mea
No known risks
A complex long-chain MEA amide used as a lipid-like hair- or skin-conditioning ingredient. These exact materials are included in CIR's newer ethanolamine and ethanolamide review work, but the older final assessment of simpler MEA ethanolamides did not establish a separate ingredient-specific pregnancy dataset for them. Their long fatty chains and amide structure support low expected systemic exposure from intact skin, and no reproductive or pregnancy-specific hazard signal was identified in the available cosmetic-use information. This no-known-risks classification is therefore evidence-limited and assumes appropriate impurity control.

Sources: CIR: Safety Assessment of Microbial Polysaccharide Gums as Used in Cosmetics; EU CosIng / cosmetics regulatory inventory
Limonene
No known risks
Limonene is a common fragrance component used at low levels in cosmetics; it is not a pregnancy-specific concern in topical use, but it is a recognised fragrance allergen and may trigger irritation or sensitisation in some people, especially if the product oxidises over time.

Direct human gestational studies and finished-product constituent levels are limited; oral, medicinal, and concentrated preparations are not covered.
Linalool
No known risks
Linalool is a common fragrance component used at low levels in cosmetics; it is not a pregnancy-specific concern in topical use, but it is a recognised fragrance allergen and may trigger irritation or sensitisation in some people, especially if the product oxidises over time.

Questions about this assessment
Why does Laneige Water Sleeping Mask have a Low risk rating?
The recorded formula includes 3 ingredient entries with risk flags: Methyl Trimethicone (Low risk), PCA Dimethicone (Low risk), Parfum (Low risk). These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail. Incomplete ingredient documentation does not establish safety; see the coverage answer and grey entries below.
Does the niacinamide rating cover every ingredient in this product?
No. Niacinamide appears in the recorded formula, but its individual rating applies to that ingredient, not automatically to the whole product. Check the other ingredient ratings, any grey Not assessed entries and the stored product assessment. A niacinamide percentage or a product name is not a substitute for checking the full list.
Has every ingredient in Laneige Water Sleeping Mask been assessed?
33 of 34 ingredient entries on this page have a recorded score, evidence summary and source text. 1 entry does not have all of those fields. Unmatched or unrated entries are marked Not assessed in grey; missing evidence does not establish safety.
Does this assessment apply to my Laneige Water Sleeping 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.
