VeriMomIs ascorbic acid safe during pregnancy?
Ascorbic acid (vitamin C, CAS 50-81-7) is not assigned a harmonised reproductive hazard (no H360/H361 in ECHA Annex VI) and has been assessed as safe for cosmetic topical use by expert panels (CIR). Mechanistically it is an antioxidant/vitamin with no established reproductive endocrine mode of action. Topical exposure can result in low but measurable systemic absorption for a small, water‑soluble molecule, so exposure is scored low (e=1). Sources: CIR safety assessment, ECHA Annex VI (no harmonised repro classification), PubChem, PubMed literature on topical vitamin C.

Frequently asked questions
- Is ascorbic acid safe during pregnancy?
- Ascorbic acid (vitamin C, CAS 50-81-7) is not assigned a harmonised reproductive hazard (no H360/H361 in ECHA Annex VI) and has been assessed as safe for cosmetic topical use by expert panels (CIR). Mechanistically it is an antioxidant/vitamin with no established reproductive endocrine mode of action. Topical exposure can result in low but measurable systemic absorption for a small, water‑soluble molecule, so exposure is scored low (e=1). Sources: CIR safety assessment, ECHA Annex VI (no harmonised repro classification), PubChem, PubMed literature on topical vitamin C.
- Is ascorbic acid safe while breastfeeding?
- No evidence of reproductive or lactation-specific hazard; no harmonised classification. Ascorbic acid is transferred into plasma when systemically present and can be present in milk if maternal systemic levels are elevated, but topical cosmetic use results in low measurable systemic exposure, so exposure is scored low (e=1). Sources: CIR, PubMed, PubChem.
- Is ascorbic acid safe for baby skin?
- No infant-specific evidence of reproductive or developmental toxicity from topical ascorbic acid; mechanism remains non‑endocrine. Because infant skin has higher surface-area-to-weight and an immature barrier, topical measurable absorption leads to an increased exposure score (+1 vs adult), giving e=2. No data justify increasing hazard or mechanism scores for infants. Sources: CIR, PubMed, CosIng, general dermal absorption principles.
- How does VeriMom score ascorbic acid?
- VeriMom scores ascorbic acid at 93/100 (no known risks) based on EU CosIng status, ECHA hazard classifications, and peer-reviewed PubMed studies. Our scoring pipeline is fully transparent.
