Willow bark is a salicin-containing botanical material. Its composition and delivered salicylate exposure vary by species, plant part, extraction method and concentration, so a cosmetic extract should not be treated as dose-equivalent to a stated concentration of salicylic acid. MamaSkin retains Low Risk as a conservative family policy for ordinary topical cosmetic use; this does not cover oral willow-bark medicines, concentrated preparations, large-area use or salicylate allergy.

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.

Aromatic alpha-hydroxy acid with larger molecular size than glycolic; penetrates more slowly and is less irritating. Topical use in cosmetic-strength peels and serums is generally regarded as low risk in pregnancy, with irritation and photosensitivity as the main concerns when overused.

Humectant and buffer that also forms part of the skin's natural moisturising factor. Reviewed cosmetic safety sources support topical cosmetic use; irritation and sun-sensitivity considerations relate more to formula context than to pregnancy-specific risk.

Dipropylene glycol is used as a solvent and carrier in cosmetics; topical exposure is low and it has no known pregnancy or breastfeeding concerns at cosmetic concentrations.

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.
Sources: CIR; EU/UK Cosmetics Regulation
A glycerin dimer used to attract moisture and improve skin feel. Cosmetic safety reviewers assessed diglycerin with related polyglycerins and concluded that they are safe in current practices of use and concentration. No pregnancy-specific concern was identified for normal topical cosmetic exposure.

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
A naturally occurring component of skin moisturizing factors, used in cosmetics as a humectant and at higher concentrations as a keratolytic. Ordinary cosmetic use does not identify a pregnancy-specific concern. Higher-strength products may sting or irritate damaged skin. Urea itself is distinct from formaldehyde-releasing preservatives such as imidazolidinyl urea and diazolidinyl urea.

A botanical extract, plant water or plant juice used for conditioning, soothing or antioxidant support. Direct pregnancy studies of this exact cosmetic material were not identified, but no reproductive or developmental hazard was identified for normal topical exposure. Oral herbal or medicinal use is outside this classification.
Sources: European Commission CosIng ingredient inventory; CIR botanical safety framework and relevant plant-derived ingredient assessments; no ingredient-specific human pregnancy study of normal topical cosmetic use was identified.
A fragrance or aroma material used at low concentrations in finished cosmetics. Irritation or contact sensitisation can occur in susceptible users, but no reproductive or developmental hazard was identified for normal topical cosmetic exposure.

Preservative acid used to help control microbial growth and support formula stability. Reviewed cosmetic safety sources support current cosmetic use, with no pregnancy- or breastfeeding-specific topical concern identified in the material reviewed; some users may still notice local irritation or stinging, especially on compromised skin.

A family of long-chain skin lipids used to condition skin and support barrier formulations. Related sphingolipids and ceramide components occur naturally in human skin. Systemic exposure from topical cosmetic use is expected to be low, and no pregnancy-specific hazard signal was identified. Source purity and local tolerability remain relevant.
