Water (Aqua) is the standard purified water used as a cosmetic solvent. It has no pregnancy-specific risk in normal topical use.

An aqueous distillate obtained by steam-distilling sea-buckthorn fruit, not plain water, seed oil or a concentrated fruit extract. No pregnancy-specific harm has been identified from ordinary topical cosmetic use; direct studies of this exact distillate in pregnancy are limited. The assessment relies on its dilute distillate preparation and topical exposure, not a claim of clinical pregnancy testing. Cosmetic purity, preservation and source-allergy controls remain important. Oral supplements and medicinal dosing are excluded.

Solvent and humectant used to improve texture and ingredient solubility. Low systemic exposure expected from topical cosmetic use.
Sources: Cosmetic Ingredient Review (US); Scientific Committee on Consumer Safety (EU)
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.

Natural polysaccharide thickener used for stability and texture. Not associated with pregnancy-specific concerns.
Sources: European cosmetics regulatory framework
A stable ether derivative of vitamin C used as an antioxidant and brightening ingredient. Pregnancy-specific topical studies are limited, but no pregnancy-specific contraindication was identified in the reviewed literature. Published case reports describe allergic contact dermatitis, so local sensitivity remains possible and this classification should not be read as proof that irritation cannot occur.

Ingredient ratings refreshed 1 October 2026. Formulas vary by market and can change. Always compare with your packaging.
No higher-risk ingredient flags are shown in the assessed entries. Ingredients without a matched rating are marked Not assessed, not No known risks. The product score is a stored assessment, not a clinical safety guarantee.
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.
20 of 20 ingredient entries on this page have a recorded score, evidence summary and source text. That describes documentation coverage, not proof that the finished formula has been clinically tested during pregnancy.
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.
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.
