Benzyl salicylate is a fragrance ingredient that is also evaluated for potential endocrine activity and sensitisation. SCCS notes some indications for endocrine mode of action, and fragrance allergens are relevant for contact allergy risk; pregnancy-specific human outcome data for topical exposure are limited. The medium-risk signal is endocrine-related uncertainty and sensitisation potential rather than a defined pregnancy-specific toxicity dataset.

Sodium laureth sulfate (SLES) is a cleansing surfactant used mainly in rinse-off products. CIR concluded sodium and ammonium laureth sulfate safe in current cosmetics when formulations are non-irritating; skin and eye irritation is the main identified concern. The review does not identify a pregnancy-specific restriction for normal cosmetic use. MamaSkin retains Low Risk, with extra care for sensitive or damaged skin.

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.

Salicylic acid is a beta-hydroxy acid (BHA) used for acne, exfoliation and preservation. Common over-the-counter acne strengths are 0.5-2%, including 0.5%, 1% and 2%; the FDA lists this acne-treatment range. Pregnancy guidance distinguishes these topical products from oral salicylates and strong peels. MotherToBaby reports that ACOG allows over-the-counter topical salicylic acid during pregnancy when needed. Only a small amount of topical acne treatment usually reaches the bloodstream through intact skin; exposure can increase with damaged skin, frequent use or treatment of large areas. Direct salicylic-acid-specific pregnancy data remain limited. MamaSkin's Low Risk rating is a dose-and-use precaution, not evidence that ordinary low-strength skincare causes fetal harm or a recommendation to avoid every BHA product. Use as directed on limited areas of intact skin. Discuss strengths above 2%, chemical peels, wart/corn removers, large-area treatment or use under occlusion with your clinician before use during pregnancy. The American Academy of Dermatology specifically advises discussing and limiting higher-strength salicylic acid above 2%. Percentage alone does not establish safety: formulation, area, frequency and skin condition also matter. General cosmetic-use limits are not pregnancy-specific safety thresholds.
