Is it suitable during pregnancy?

MamaSkin rates the recorded formula for Round Lab Birch Juice Moisturizing Sun Serum 50ml as Low risk (78/100). Review the ingredient context and any manual-review explanation before deciding.

Why this rating?

The recorded formula includes 4 ingredient entries with risk flags: Dimethicone (Low risk), Methyl Trimethicone (Low risk), Dimethicone/Vinyl Dimethicone Crosspolymer (Low risk), plus others listed in the breakdown. These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail.

62 of 63 ingredient entries on this page have a recorded score, evidence summary and source text. 1 entry does not have all of those fields. Unmatched or unrated entries are marked Not assessed in grey; missing evidence does not establish safety.

Dimethicone

Low risk

Dimethicone is a silicone polymer used as a skin protectant and slip/conditioning agent. It is considered inert with minimal dermal absorption; the main practical issues are cosmetic (feel) and occasional irritation in very sensitive users. It is not a pregnancy-specific concern in topical cosmetic use.

Methyl Trimethicone

Low risk

A lightweight volatile linear silicone used as a solvent and texture ingredient. Related linear methicone ingredients have reassuring cosmetic safety assessments, but an exact final Cosmetic Ingredient Review finding for Methyl Trimethicone was not located. MamaSkin classifies it as low risk because exact-ingredient pregnancy and inhalation data are limited, while no specific pregnancy contraindication has been identified for normal topical cosmetic use.

Dimethicone/Vinyl Dimethicone Crosspolymer

Low risk

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.

Sources: CIR: Safety Assessment of Dimethicone Crosspolymers as Used in Cosmetics https://www.cir-safety.org/sites/default/files/dimethcross_blue_092012.pdf

Sodium DNA

Low risk

DNA-derived cosmetic ingredient/label term used in topical PDRN or polynucleotide-style skincare. Topical cosmetic use is not currently treated as a known pregnancy-restricted concern, but pregnancy-specific clinical data remain limited. MamaSkin scores this conservatively as low risk to reflect the evidence gap. This assessment applies to topical cosmetic products only and does not apply to injectable or in-clinic PDRN/polynucleotide treatments. Always review co-ingredients such as retinoids, hydroquinone, high-strength acids or other pregnancy-restricted actives separately.

Diethylamino Hydroxybenzoyl Hexyl Benzoate

No known risks

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.

Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine

No known risks

Modern broad-spectrum UV filter (often known as Tinosorb S). It has a high molecular weight and is formulated to remain mainly in the outer skin layers, with very low systemic absorption at cosmetic use levels. EU regulatory assessments and independent risk–benefit reviews have evaluated this filter as safe up to 10% in sunscreens, with no specific reproductive or developmental toxicity signals identified in animals or humans at permitted concentrations.

Sources: European Union Cosmetic Products Regulation (Annex VI): Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine listed as an approved UV filter up to 10% in cosmetic products. Mikkelsen SH et al. “Survey and health assessment of UV filters” – Danish EPA, 2015: includes Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine and notes low systemic exposure at approved use levels.

Questions about this assessment

Why does Round Lab Birch Juice Moisturizing Sun Serum 50ml have a Low risk rating?

The recorded formula includes 4 ingredient entries with risk flags: Dimethicone (Low risk), Methyl Trimethicone (Low risk), Dimethicone/Vinyl Dimethicone Crosspolymer (Low risk), plus others listed in the breakdown. These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail. Incomplete ingredient documentation does not establish safety; see the coverage answer and grey entries below.

Does this assessment cover injectable PDRN treatments?

No. The recorded ingredient list includes a DNA ingredient used in a topical cosmetic. This page assesses that recorded cosmetic formula, not injections, a clinic procedure or every product sold as PDRN. Check the individual ingredient entry below for its available rating and evidence.

Has every ingredient in Round Lab Birch Juice Moisturizing Sun Serum 50ml been assessed?

62 of 63 ingredient entries on this page have a recorded score, evidence summary and source text. 1 entry does not have all of those fields. Unmatched or unrated entries are marked Not assessed in grey; missing evidence does not establish safety.

Does this assessment apply to my Round Lab Birch Juice Moisturizing Sun Serum 50ml?

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.
