Polyhydroxy acid (PHA) used as a gentle exfoliant/humectant; generally less irritating than AHAs due to lower penetration. Considered safe as used in cosmetics, with no pregnancy-specific contraindications identified at topical cosmetic concentrations.

Blue tansy is Tanacetum annuum, not the thujone-rich common tansy Tanacetum vulgare. Available composition studies describe a variable concentrated essential oil but do not establish a reproductive or developmental hazard from normal topical cosmetic exposure. MamaSkin applies Low Risk for limited pregnancy data and essential-oil sensitisation or composition uncertainty, not as a contraindication.

Endogenous alpha-hydroxy acid and humectant; at modest cosmetic concentrations (≈5% and below, and generally <10%) topical lactic acid is considered compatible with pregnancy. Main risks are local irritation and increased photosensitivity rather than systemic toxicity or fetal effects.

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.

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.
Sources: CIR; EU/UK Cosmetics Regulation
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.
Sources: CIR; EU/UK Cosmetics Regulation
Polyglycerin fatty-acid ester used as an emulsifier and solubilizer. Reviewed cosmetic safety references do not identify a pregnancy- or breastfeeding-specific concern for normal topical cosmetic use.

Skin-identical barrier lipid used to support the stratum corneum and reduce dryness. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific topical signal identified in the material reviewed.
Sources: CIR: Safety Assessment of Ceramides as Used in Cosmetics; EU CosIng / cosmetics regulatory inventory
Skin-conditioning lipid used in barrier-support formulas, often alongside ceramides and fatty acids. Normal topical cosmetic use has no known pregnancy- or breastfeeding-specific concern identified in reviewed cosmetic references.

Common emollient derived from fatty acids and glycerin. Used to soften skin and improve texture without pregnancy-specific concerns.
Sources: Cosmetic Ingredient Review (US); Scientific Committee on Consumer Safety (EU)
Skin-conditioning lipid used in barrier-support formulas, commonly alongside ceramides and cholesterol. Reviewed cosmetic ingredient references do not identify a pregnancy- or breastfeeding-specific concern for normal topical use.

Stearic acid is a fatty acid used to stabilise emulsions and improve texture; it is considered low concern in topical cosmetics with no known pregnancy or breastfeeding risks at typical concentrations.
Sources: CIR; EU/UK Cosmetics Regulation
This naturally occurring fatty acid is used for emolliency, cleansing support or texture. The Cosmetic Ingredient Review concluded that assessed fatty acids are safe in current cosmetic use when formulated to be non-irritating and non-sensitizing; some can increase penetration of other formula ingredients.

Hydrogenated emulsifier used to support skin barrier feel. Not associated with pregnancy-specific concerns.
Sources: Cosmetic Ingredient Review (US)
Preservative booster and skin-conditioning agent. Considered safe for cosmetic use with low systemic exposure when used as intended.
Sources: Scientific Committee on Consumer Safety (EU); Cosmetic Ingredient Review (US)
Sodium hyaluronate (hyaluronic acid salt) is used for hydration and cushioning, with very low systemic absorption from topical use and no known pregnancy or breastfeeding concerns at cosmetic concentrations.
Sources: CIR; EU/UK Cosmetics Regulation
Cellulose-derived thickener used to build viscosity and improve texture. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific topical signal identified in the material reviewed.
Sources: CIR Quick Reference Table / ingredient status (Hydroxyethylcellulose, Final Report 03/2009); EU CosIng / cosmetics regulatory inventory
Polymer thickener used to stabilise emulsions. Large-molecule ingredient with low systemic absorption.
Sources: Cosmetic Ingredient Review (US); Scientific Committee on Consumer Safety (EU)
A high-molecular-weight polymer used to hold water and stabilise texture. Cosmetic safety reviewers concluded that glyceryl acrylate/acrylic acid copolymer is safe in current cosmetic practices. Dermal absorption of the finished polymer is expected to be limited; residual monomers should be controlled by cosmetic manufacturing standards.

Humectant and preservative booster used to support product stability. Low systemic exposure expected from topical cosmetic use.
Sources: Scientific Committee on Consumer Safety (EU); Cosmetic Ingredient Review (US)
A chelating ingredient commonly used to support cosmetic preservation. Cosmetic safety reviewers concluded that caprylhydroxamic acid is safe in current cosmetic use; sensitisation and enhanced penetration are formulation considerations, especially on damaged skin, but no pregnancy-specific contraindication is identified for normal topical use.

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.
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.
