Tatcha The Dewy Skin Cream

A crosslinked silicone elastomer used for texture and oil absorption. Cosmetic safety reviewers concluded that dimethicone crosspolymers are safe in current cosmetic use. MamaSkin classifies the exact polymer as low risk for consistency with the existing dimethicone-family policy and because manufacturing controls are needed for residual monomers, rather than because of a known pregnancy-specific contraindication.

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.

A fermentation-derived cosmetic ingredient used for conditioning or formula support. Composition depends on the organism, substrate and manufacturing controls. No pregnancy-specific reproductive or developmental hazard was identified for normal topical exposure; ingestion is outside this classification.

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.

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

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

Emollient ester commonly used in lip, makeup and skin-care formulas for cushion and gloss. Reviewed cosmetic ingredient references do not identify a pregnancy- or breastfeeding-specific concern for normal topical cosmetic use.

Long-chain fatty alcohol used as an emollient and thickener. This is not the same concern profile as simple drying alcohols; reviewed cosmetic safety sources support normal topical use.

A fatty-acid ester used mainly for emollience, slip and formula texture. Cosmetic safety reviewers concluded that the assessed alkyl esters are safe in current practices when formulated to be non-irritating. No pregnancy-specific concern was identified for normal topical cosmetic exposure.

Emollient ester used in lip, makeup and skin-care formulas for cushion, gloss and barrier feel. Reviewed cosmetic ingredient references do not identify a pregnancy- or breastfeeding-specific concern for normal topical use.

A high-molecular-weight ester used as an emollient and film-forming texture agent. Cosmetic safety reviewers concluded that trialkyl trimellitates, including tridecyl trimellitate, are safe in current practices when formulated to be non-irritating. Dermal absorption is expected to be limited.

A naturally occurring sugar alcohol used for conditioning and hydration. Cosmetic safety reviewers concluded that inositol is safe in current practices of use and concentration. No pregnancy-specific concern was identified for normal topical cosmetic exposure.

A fatty ester, lipid-derived emulsifier or emollient used for texture and skin conditioning. These materials have low expected systemic exposure, and no pregnancy-specific reproductive or developmental hazard was identified for normal topical cosmetic use.

Camellia sinensis (green tea) leaf extract is used as an antioxidant botanical; topical cosmetic use is considered low concern with no known pregnancy or breastfeeding risks, though rare sensitivities are possible.

A red-algae-derived extract used for skin conditioning, hydration or formula texture. Cosmetic safety reviewers concluded that the assessed red algae ingredients, including this extract, are safe in current practices of use and concentration. Cosmetic manufacturers should control naturally occurring contaminants such as heavy metals and arsenic.

A rice-derived extract or wax used for skin conditioning, absorbency or texture. Cosmetic safety reviewers concluded that the assessed Oryza sativa-derived ingredients are safe in current cosmetic practices. Rice allergy remains possible in a susceptible person.

A botanical root extract used as a skin-conditioning and antioxidant ingredient. Cosmetic safety reviewers concluded that Panax root-derived ingredients are safe in current practices of use and concentration. The assessment considered the biological activity of ginsenosides and available reproductive and developmental information; ordinary topical cosmetic exposure was not identified as a pregnancy-specific concern. Botanical irritation or allergy remains possible.

malva sylvestris flower extract is a botanical-derived cosmetic conditioning ingredient. The reviewed identity is not an essential oil or an oral herbal preparation. Available cosmetic evidence and expected topical exposure did not identify a pregnancy-specific contraindication, although botanical irritation or allergy remains possible.

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.

An insoluble mineral or elemental particle used for optical effects, absorbency or cosmetic texture. Meaningful systemic exposure through intact skin is expected to be low. No pregnancy- or reproductive-toxicity signal was identified for normal topical cosmetic use. Particle size, source purity, metal impurities and inhalation of airborne powder remain formulation-specific considerations, and local contact allergy is possible with gold.

sericin is a cosmetic protein, amino-acid mixture or peptide used for conditioning. Expected systemic exposure from normal topical use is low. Manufacturing quality should minimise residual allergenic proteins where relevant; no pregnancy-specific concern was identified for normal cosmetic exposure.

A plant-derived wax, sterol fraction or oil unsaponifiable used for emollience and formula structure. Related source oils, waxes and phytosterols are established cosmetic ingredients, and no reproductive or developmental hazard signal was identified for normal topical exposure. Botanical source purity and individual contact allergy remain formulation-specific considerations.

Vitamin E antioxidant used to protect oils and support the skin barrier. Not associated with pregnancy-specific concerns at cosmetic exposure.

Large polymer thickener, stabilizer and texture ingredient used in gels, creams and sunscreens. Systemic exposure from topical cosmetic use is expected to be low, with no pregnancy- or breastfeeding-specific concern identified in reviewed cosmetic references.

Emulsifier used to help oil and water phases remain mixed. Reviewed cosmetic safety sources support topical use in cosmetics; the main practical issue is irritation potential in some formulas rather than a pregnancy-specific concern.

Nonionic emulsifier and solubilizer used to help oil and water phases mix. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific topical signal identified.

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

Preservative widely used in foods and cosmetics. Considered safe at regulated concentrations with low systemic exposure from topical use.

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

Volatile solvent used in some toners, sprays, and lightweight formulas. Reviewed cosmetic safety sources support current cosmetic use, with no pregnancy- or breastfeeding-specific topical concern identified in the material reviewed; the main practical issue is dryness, stinging, or barrier disruption in some users.

A lemon-scented mixture of the aldehydes geranial and neral used in fragrance. Citral is a recognised skin sensitiser, but current cosmetic concerns relate to allergy and concentration rather than a pregnancy-specific hazard from normal topical use.

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.

Mineral platelet used to add shimmer and improve texture in makeup and skincare. Very low dermal absorption in typical topical use and generally considered acceptable in pregnancy and breastfeeding. If you prefer a cautious approach, avoid inhaling loose powders or sprays.

Mineral ingredient used in some cosmetics to enhance shimmer/opacity. For typical topical use, dermal absorption is very low and it is generally considered acceptable in pregnancy and breastfeeding. If you prefer a cautious approach, avoid inhaling loose powders or sprays.

Colour Index name for titanium dioxide. Used as a pigment and (in some products) a mineral UV filter. For typical topical use in creams, lotions and makeup, systemic absorption is expected to be very low. Most concerns discussed in the literature relate to ingestion (E171) or inhalation from fine powders/sprays, and to nanoparticle characterisation. For routine topical cosmetic use, it is generally considered acceptable in pregnancy and breastfeeding; if you prefer a cautious approach, avoid inhaling loose powders or sprays.
