Ingredient ratings and evidence
Higher-risk flags first. Open an ingredient for evidence.
Arbutin
Medium risk
Arbutin (beta-arbutin) is a skin-brightening ingredient and a glycosylated hydroquinone. Key concerns are potential hydroquinone release/contamination, dermal absorption, and combined exposure when multiple hydroquinone-releasing substances are used across products. Pregnancy-specific human outcome data for topical cosmetic exposure are limited; the medium-risk signal is hydroquinone-related concern plus limited pregnancy-specific evidence.

Glycyrrhiza Glabra Root Extract
Low risk
Pregnancy concerns around licorice are based mainly on high oral glycyrrhizin intake, which has been linked to shorter gestation and cortisol-related effects in offspring; by contrast, licorice root extracts have been assessed as safe as used in cosmetics, so routine topical skincare exposure fits a cautious low-risk classification.

1,2-Hexanediol
No known risks
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.
Sources: CIR; EU/UK Cosmetics Regulation
Propanediol
No known risks
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)
Betaine
No known risks
Betaine is a humectant/osmolyte used to support hydration and reduce irritation potential in formulas; it is considered low concern with no known pregnancy or breastfeeding risks in topical cosmetic use.
Sources: CIR; EU/UK Cosmetics Regulation
3-O-Ethyl Ascorbic Acid
No known risks
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.

Sources: Cosmetic Ingredient Review (US); Scientific Committee on Consumer Safety (EU)
Tromethamine
No known risks
pH adjuster and buffer used to stabilise formulations. Reviewed cosmetic safety sources support normal topical use, with no pregnancy- or breastfeeding-specific topical signal identified in the material reviewed.

Trisodium Ethylenediamine Disuccinate
No known risks
Chelating ingredient used to improve formula stability by binding trace metals. Reviewed cosmetic ingredient references do not identify a pregnancy- or breastfeeding-specific concern for normal topical use.
Sources: CIR cosmetic ingredient safety references for chelating agents; EU CosIng / cosmetics regulatory inventory
Theobroma Cacao Seed Extract
No known risks
A cosmetic extract from an edible fruit, seed, grain, root or mushroom used for conditioning or antioxidant support. Normal topical cosmetic exposure is much lower than ordinary dietary exposure to the source material, and no pregnancy-specific hazard signal was identified. Exact extract composition varies, so source quality and individual food or plant allergy remain relevant.

Questions about this assessment
Why does Good Molecules Niacinamide Brightening Toner have a Medium risk rating?
The recorded formula includes 2 ingredient entries with risk flags: Arbutin (Medium risk), Glycyrrhiza Glabra Root Extract (Low risk). These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail. The product score is a stored assessment, not a clinical safety guarantee.
Does the niacinamide rating cover every ingredient in this product?
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.
Has every ingredient in Good Molecules Niacinamide Brightening Toner been assessed?
17 of 17 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 Good Molecules Niacinamide Brightening 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.
