Laneige Water Sleeping Mask

Water (aqua) is the purified solvent used as the base of many cosmetics. MamaSkin classifies plain water as No known risks for normal topical use. Cosmetic water quality must be controlled to prevent contamination; this entry does not cover botanical waters or establish the safety of the finished formula.

Solvent and humectant commonly used in leave-on products. Not associated with pregnancy-specific concerns at cosmetic exposure levels.

Glycerin is a widely used humectant that supports hydration and the skin barrier, with a long safety record and no known pregnancy or breastfeeding concerns in topical cosmetic use.

Skin-identical barrier lipid used to support barrier function and reduce dryness. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific topical signal identified in the material reviewed.

1,2-Hexanediol is commonly used as a solvent and preservative booster; topical exposure is low and it has no known pregnancy or breastfeeding concerns at cosmetic concentrations, though very sensitive skin may occasionally react.

Lightweight emollient used to support the skin barrier. Not associated with pregnancy-specific concerns at cosmetic exposure levels.

Silicone emollient used to improve slip, gloss, and water resistance. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific topical signal identified in the material reviewed.

Volatile/low-residue silicone emollient used to improve spreadability and sensory feel. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific topical signal identified in the material reviewed.

Polymer thickener used to stabilise emulsions. Large-molecule ingredient with low systemic absorption.

A lysate produced from Lactobacillus fermentation and used for skin conditioning. Cosmetic safety reviewers concluded that Lactobacillus ferment lysate is safe in current practices of use and concentration.

Polymer thickener used to create gel textures. Large-molecule ingredient with negligible systemic absorption.

Solvent and humectant used to improve texture and ingredient solubility. Low systemic exposure expected from topical cosmetic use.

pH adjuster and buffer used to stabilise formulations. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific topical signal identified in the material reviewed.

Polymer thickener and stabiliser used in creams and sunscreens. Low systemic exposure expected.

Emollient, co-emulsifier and preservative-support ingredient used in topical cosmetics. Reviewed cosmetic ingredient references do not identify a pregnancy- or breastfeeding-specific concern for normal topical use.

Preservative booster and skin-conditioning agent. Considered safe for cosmetic use with low systemic exposure when used as intended.

Disodium EDTA is a chelating agent used to improve formula stability and performance; it is considered low concern in topical cosmetic use, with no known pregnancy or breastfeeding risks at typical concentrations.

raffinose is a sugar-derived humectant, polysaccharide or gum used for hydration and texture. Relevant cosmetic assessments and low expected dermal absorption did not identify a pregnancy-specific concern for normal topical use. Cosmetic-grade purity and ordinary sensitivity precautions remain applicable.

stearyl behenate is a cosmetic formulation, mineral, sugar-derived or organic-acid ingredient. Available identity, use and related safety evidence did not identify a pregnancy-specific concern for normal topical cosmetic exposure. Cosmetic-grade purity and ordinary irritation precautions remain applicable.

A mineral-derived cosmetic material used for colour, absorbency or conditioning. Dermal absorption is expected to be limited and no reproductive or developmental concern was identified for normal compliant topical use.

An emulsifier built from polyglycerin, methyl glucose and stearic-acid components, used to stabilise creams and improve texture. Exact pregnancy-specific data are limited. Cosmetic safety reviewers concluded that related methyl glucose esters and polyglyceryl fatty-acid esters are safe in current cosmetic use when formulated to be non-irritating. No pregnancy-specific topical concern was identified by applying those related-group assessments to ordinary cosmetic exposure.

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.

Niacinamide (vitamin B3) is widely used for barrier support and tone/texture benefits, and is generally considered safe in pregnancy and breastfeeding when used topically at cosmetic concentrations.

An amino acid or amino-acid mixture used for hydration and conditioning. No pregnancy-specific hazard was identified for normal topical exposure.

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.

Film-forming polysaccharide used for soothing and hydration support. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific topical signal identified in the material reviewed.

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.

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.
