Frequently asked questions

Is lactobacillus safe during pregnancy?
No harmonised CLP reproductive classifications for Lactobacillus (ECHA Annex VI) and no CIR or SCCS safety findings indicating reproductive toxicity. Clinical/peer-reviewed literature on probiotic Lactobacillus use in pregnancy (oral administration) generally reports no teratogenic or reproductive hazards, and topical cosmetic use gives negligible systemic exposure (PubMed, CosIng; see sources).
Is lactobacillus safe while breastfeeding?
No evidence of reproductive or lactation-specific hazard from Lactobacillus in regulatory databases. Maternal probiotic use may alter milk microbiota in some studies but has not been shown to cause harm to breastfed infants; topical cosmetic application has negligible systemic exposure (PubMed, CosIng, EWG).
Is lactobacillus safe for baby skin?
No evidence of reproductive or developmental toxicity specific to topical Lactobacillus. Mechanistic reproductive concerns are not identified. Exposure rating increased to 1 for infants (0–3 yr) because infant skin has a less mature barrier and higher surface-area-to-weight ratio, so any ingredient with potential for measurable percutaneous uptake is assigned higher exposure even though topical bacteria themselves are not typically systemically absorbed (PubMed, CosIng, EWG). Note: rare risk of infection from live microorganisms in severely immunocompromised infants is described in clinical literature but not a reproductive/toxicological classification.
How does VeriMom score lactobacillus?
VeriMom scores lactobacillus at 100/100 (no known risks) based on EU CosIng status, ECHA hazard classifications, and peer-reviewed PubMed studies. Our scoring pipeline is fully transparent.
