Frequently asked questions
- Is streptococcus thermophilus ferment safe for baby skin?
- No evidence of developmental or reproductive toxicity specific to infants. Adult dermal absorption from a high‑molecular‑weight proteinaceous ferment is expected to be negligible (adult e=0), but per guidance immature infant skin may permit modestly higher exposure, so exposure score increased to 1 for 0–3 yr. No mechanistic or hazard data indicate infant‑specific reproductive risk.
