Ingredients

Ingredients with a higher risk flag appear first, followed by the rest of the formula.

Alpha-Arbutin

Medium Risk

Alpha-arbutin is a skin-brightening ingredient that inhibits tyrosinase and can be viewed as a glycosylated hydroquinone. The central safety signal is potential hydroquinone release/contamination plus systemic exposure from dermal absorption and aggregate exposure across multiple product types. Pregnancy-specific human outcome data for topical cosmetic exposure are limited; the medium-risk signal is hydroquinone-related concern and uncertainty rather than a robust pregnancy-specific safety dataset.

Tranexamic Acid

Low Risk

Synthetic lysine analogue used topically for melasma and hyperpigmentation; inhibits plasmin activity and downstream melanogenesis. Topical formulations (≈2–5%) show low systemic absorption and no reported teratogenic effects, but pregnancy-specific data remain limited. Many sources regard it as pregnancy-safe or acceptable, while some advise cautious use or deferral until after pregnancy due to limited evidence.

Hippophae Rhamnoides Water

No Known Risks

hippophae rhamnoides water 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.

How to use this assessment

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.
