Round Lab Birch Juice Moisturizing Sun Serum 50ml

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.

A botanical extract, juice or water used primarily for skin conditioning, moisturising, soothing or antioxidant support. Direct pregnancy studies of the named cosmetic material were not identified. No reproductive or developmental hazard was identified for normal topical exposure to a compliant finished cosmetic; oral herbal or medicinal use is outside this classification.

Glycerin is a widely used humectant that supports hydration and the skin barrier, with a long safety record and no known pregnancy or breastfeeding concerns in topical cosmetic use.

A diester used as an emollient, solvent and plasticizer. After reviewing additional dermal, reproductive, developmental and genotoxicity data, cosmetic safety reviewers concluded that dibutyl adipate is safe in current cosmetic use and concentration. No pregnancy-specific concern is identified for normal topical cosmetic exposure.

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.

Silicone-based organic UVB filter used in sunscreens and UV-protective cosmetics. SCCS reviewed Polysilicone-15 for cosmetic use, and no pregnancy- or breastfeeding-specific topical concern was identified in the sources reviewed.

Humectant and preservative booster. Considered safe for cosmetic use with low systemic exposure.

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.
