Alpha-Arbutin 2%
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.

Coptis Japonica Root Extract
Low risk
Coptis japonica root contains isoquinoline alkaloids including berberine. Oral berberine has limited pregnancy data and precautionary concerns involving uterine activity and bilirubin displacement, while breastfeeding exposure is also discouraged. A cosmetic extract is used topically at much lower exposure and may vary in composition, so MamaSkin applies a precautionary Low Risk classification rather than an oral-supplement-level warning.

Questions about this assessment
Why does Beauty of Joseon Glow Deep Serum: Rice + Arbutin have a Medium risk rating?
The recorded formula includes 2 ingredient entries with risk flags: Alpha-Arbutin 2% (Medium risk), Coptis Japonica 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 Beauty of Joseon Glow Deep Serum: Rice + Arbutin been assessed?
32 of 32 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 Beauty of Joseon Glow Deep Serum: Rice + Arbutin?
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.
