MamaSkin rates the recorded formula for Round Lab Birch Juice Moisturizing Tone Up Sunscreen SPF 50+ PA++++ as Low risk (79/100). Review the ingredient context and any manual-review explanation before deciding.
The recorded formula includes 2 ingredient entries with risk flags: Dipotassium Glycyrrhizate (Low risk), Dimethicone/Vinyl Dimethicone Crosspolymer (Low risk). These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail.
49 of 49 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.

A purified glycyrrhizic-acid salt used as a soothing and skin-conditioning ingredient. Cosmetic safety reviewers concluded that dipotassium glycyrrhizate is safe in current cosmetic use and noted poor dermal absorption. MamaSkin nevertheless applies a cautious low-risk classification for consistency with the existing licorice family because high oral glycyrrhizin exposure has pregnancy-related concerns; this is not a topical contraindication.

A crosslinked silicone elastomer used for texture and oil absorption. Cosmetic safety reviewers concluded that dimethicone crosspolymers are safe in current cosmetic use. MamaSkin classifies the exact polymer as low risk for consistency with the existing dimethicone-family policy and because manufacturing controls are needed for residual monomers, rather than because of a known pregnancy-specific contraindication.

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)
Inorganic mineral pigment and, in some products, a mineral UV filter. For typical topical use in creams, lotions and makeup, systemic absorption is expected to be very low. Most concerns discussed in the literature relate to ingestion (food additive E171) or inhalation exposure from fine powders/sprays, and to specific nanoparticle characterisation. For routine topical cosmetic use, it is generally considered acceptable in pregnancy and breastfeeding; if you prefer a cautious approach, avoid inhaling loose powders or sprays.

Alkyl benzoate emollient used in cosmetics; available cosmetic safety assessments do not indicate pregnancy-specific concerns with routine topical use.
Sources: CIR Safety Assessment of Alkyl Benzoates (2012); CIR alkyl benzoates dossier / C12-15 alkyl benzoate data.
Modern UVA filter (often called Uvinul A+ or DHHB). Regulatory assessments have repeatedly evaluated this filter as safe in cosmetic products at concentrations up to 10%. The most recent SCCS advice focuses on controlling a manufacturing impurity (DnHexP) rather than on new toxicity of DHHB itself. Human biomonitoring data indicate low systemic exposure from normal sunscreen use, and current reviews do not identify specific reproductive or developmental toxicity signals at approved concentrations.
Sources: SCCP opinion referenced in Directive 2008/123/EC: concludes that Diethylamino Hydroxybenzoyl Hexyl Benzoate used at a maximum of 10% in cosmetic (including sunscreen) products does not pose a risk to the consumer. Regulatory summaries (e.g. CosLaw and CIRS Group updates, 2025) reviewing the SCCS DHHB opinion and reiterating that DHHB remains permitted up to 10% in EU cosmetics when impurity limits are respected.

The recorded formula includes 2 ingredient entries with risk flags: Dipotassium Glycyrrhizate (Low risk), Dimethicone/Vinyl Dimethicone Crosspolymer (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.
No. The score and risk band describe MamaSkin's pregnancy-focused ingredient screening of this recorded formula. They do not measure SPF, UVA protection, water resistance or whether you have applied enough sunscreen. Use the protection and application instructions on your exact packaging, and review the ingredient flags separately.
49 of 49 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.
