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
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)
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.
Sources: CIR; EU/UK Cosmetics Regulation
The cosmetic manufacturer identifies uniform rice-hull particles for wet exfoliating formulations. Superficial fiber/mineral particle exposure in non-injurious intact-skin use supplies the ordinary-route rationale; no pregnancy-specific concern is identified for this controlled cosmetic preparation. Rice and synthetic amorphous-silica assessments offer only constituent/particle context and do not directly assess every natural hull grade. Crystalline-silica/contaminant controls remain important. This excludes calcined hull ash, inhalable loose dust, engineered nanoparticles, extracts and damaged-skin delivery; stated use levels are not pregnancy-safe ceilings.

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.

Rice bran is a specifically assessed rice-derived cosmetic ingredient. The published amended review supports the named rice preparations at current uses. No pregnancy-specific harm has been identified from ordinary topical cosmetic exposure; direct human pregnancy studies are limited. This does not clear rice hull powder, every rice water or fermentation product, oral concentrates or raw material with uncontrolled impurities.
oryza sativa lees extract is a botanical-derived cosmetic conditioning ingredient. The reviewed identity is not a concentrated 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.

35 of 35 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.
