Frequently asked questions

Is lac safe for baby skin?
Hazard and mechanism: no data suggesting reproductive/teratogenic hazard to infants from topical LAC. Exposure: adult topical absorption is negligible for intact milk proteins/polymers (adult e=0), but per instruction a +1 exposure score is applied for baby skin because infants have higher surface‑area‑to‑weight and immature barrier and LAC is not completely non‑absorbable (so baby e=1). Topical milk is commonly used on infant skin; main concern would be allergenicity if proteins contact broken skin, not reproductive toxicity.
