MamaSkin rates the recorded formula for La Roche-Posay Hyalu B5 Face Serum with Hyaluronic Acid as Low risk (74/100). Review the ingredient context and any manual-review explanation before deciding.
The recorded formula includes 3 ingredient entries with risk flags: Dimethicone (Low risk), Phenoxyethanol (Low risk), Parfum (Low risk). These are ingredient-level flags; they do not replace the stored product assessment or account for every formulation detail.
22 of 22 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.

Phenoxyethanol is a preservative permitted in EU cosmetics up to 1.0%. The SCCS concluded it is safe for cosmetic use at that level, including when considering higher cosmetic exposure scenarios in infants and young children. Main practical concern is irritation/stinging on very sensitive or compromised skin rather than a pregnancy- or breastfeeding-specific risk.

Umbrella term for an undisclosed fragrance blend. It’s not usually a pregnancy-specific concern at normal cosmetic use levels, but the exact components and concentrations aren’t fully disclosed on the label, so we score it more conservatively. If you prefer maximum transparency (or you’re sensitive to fragrance compounds), choose fragrance-free/unscented products.

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.

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.
Sources: CIR; EU/UK Cosmetics Regulation
Volatile solvent used to improve texture, drying time, and penetration in some formulas. Reviewed cosmetic safety sources support current cosmetic use, with no pregnancy- or breastfeeding-specific topical concern identified in the material reviewed; the main practical issue is dryness, stinging, or barrier disruption in some users.

Propylene glycol is a common solvent and humectant with a long history of use; it is not considered a pregnancy or breastfeeding concern in topical cosmetics, though some individuals may experience irritation in leave-on products.
Sources: CIR; EU/UK Cosmetics Regulation
Panthenol (pro-vitamin B5) is used for soothing and barrier support and is generally well tolerated, with no known pregnancy or breastfeeding concerns in topical cosmetic use.
Sources: CIR; EU/UK Cosmetics Regulation
Humectant and preservative booster. Considered safe for cosmetic use with low systemic exposure.

An ethoxylated glyceride used as a surfactant, solubiliser or emollient. Cosmetic safety reviewers concluded that PEG-6 caprylic/capric glycerides are safe in current practices when formulated to be non-irritating. Manufacturing should control ethylene oxide and 1,4-dioxane residues.

ppg-6-decyltetradeceth-30 is a cosmetic surfactant, emulsifier or conditioning agent. Relevant CIR family assessments support use when formulated to be non-irritating and with appropriate impurity controls. Local skin or eye irritation is possible, but no pregnancy-specific concern was identified for normal topical or rinse-off use.

A fatty ester, lipid-derived emulsifier or emollient used for texture and skin conditioning. These materials have low expected systemic exposure, and no pregnancy-specific reproductive or developmental hazard was identified for normal topical cosmetic use.

A triterpene glycoside associated with Centella asiatica and used in soothing and skin-conditioning formulas. Pregnancy-specific evidence for isolated topical madecassoside is limited. Cosmetic safety reviewers considered Centella-derived ingredients acceptable at current cosmetic exposure but noted that madecassoside and related triterpenes may contribute to sensitisation, so products should be formulated to avoid sensitising concentrations. No pregnancy-specific topical contraindication was identified in the reviewed material.

Sodium hyaluronate (hyaluronic acid salt) is used for hydration and cushioning, with very low systemic absorption from topical use and no known pregnancy or breastfeeding concerns at cosmetic concentrations.
Sources: CIR; EU/UK Cosmetics Regulation
A high-molecular-weight polymer used to thicken and stabilise formulas. Cosmetic safety reviewers concluded that acryloyldimethyltaurate polymers are safe in current cosmetic practices. Absorption of the finished polymer is expected to be limited, with residual monomers controlled during manufacture.

The recorded formula includes 3 ingredient entries with risk flags: Dimethicone (Low risk), Phenoxyethanol (Low risk), Parfum (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. This recorded formula contains Panthenol or Madecassoside, but a barrier-care claim does not establish the assessment of all its other ingredients. Read the individual ingredient evidence and any manual-review explanation, and compare the recorded list with your packaging.
22 of 22 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.
