Is it suitable during pregnancy?

MamaSkin rates the recorded formula for BYOMA Hydrating Milky Toner as Medium risk (58/100). Discuss the flagged ingredients with a qualified healthcare professional before using this formula during pregnancy.

Why this rating? Manual-review explanation

Newly reviewed ingredient guidance: this product is now Medium Risk as a precaution because its comfrey root extract may contain pyrrolizidine alkaloids and the ingredient list does not establish their levels. This does not mean that ordinary cosmetic use has been shown to harm a pregnancy. Newly assessed ingredient: symphytum officinale root extract.

29 of 29 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.

Ingredient ratings and evidence

Higher-risk flags first. Open an ingredient for evidence.

Symphytum Officinale Root Extract

Medium risk

Comfrey root extract can contain unsaturated pyrrolizidine alkaloids associated with liver toxicity and genotoxicity. EMA's 2024 root monograph also describes fetal liver toxicity after high-dose oral exposure to an isolated alkaloid in animals; this is not evidence that an ordinary cosmetic causes the same exposure or outcome. Specified adult topical medicines require measured alkaloid limits and short-term use, and are not recommended during pregnancy or breastfeeding. The INCI name alone does not establish alkaloid removal or a controlled dose. MamaSkin applies precautionary Medium Risk, consistently with comfrey leaf extract, rather than assuming a purified grade. This is not proof of harm from every finished cosmetic. A documented alkaloid-controlled product would require a separate composition-and-exposure assessment; there is no validated cosmetic pregnancy-safe percentage for this extract.

Gluconolactone

Low risk

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.

Questions about this assessment

Why does BYOMA Hydrating Milky Toner have a Medium risk rating?

Newly reviewed ingredient guidance: this product is now Medium Risk as a precaution because its comfrey root extract may contain pyrrolizidine alkaloids and the ingredient list does not establish their levels. This does not mean that ordinary cosmetic use has been shown to harm a pregnancy. Newly assessed ingredient: symphytum officinale root extract. The product score is a stored assessment, not a clinical safety guarantee.

Does a barrier-care product name establish pregnancy suitability?

No. This recorded formula contains Panthenol or Madecassoside, but a barrier-care claim does not establish the assessment of all its other ingredients. Read the individual ingredient evidence and any manual-review explanation, and compare the recorded list with your packaging.

Has every ingredient in BYOMA Hydrating Milky Toner been assessed?

29 of 29 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.

Does this assessment apply to my BYOMA Hydrating Milky Toner?

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.

Does this pregnancy assessment also establish breastfeeding suitability?

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.
