Niacinamide is a mild form of vitamin B3 that is usually low risk. For newborns and babies (0–6 months) we recommend being careful because their skin soaks up things more easily.
If you want to use a product with niacinamide on a baby: choose a gentle, fragrance-free baby moisturizer that lists niacinamide low on the ingredient list or in a low concentration; avoid adult serums or strong treatments; do a small patch test on one area and wait 24–48 hours; and check with your pediatrician before using it regularly on a newborn.
Do not put high-strength niacinamide serums or active treatments on an infant’s skin. Stop use and call your pediatrician if you see redness, swelling, stinging, or any allergic reaction. The caution comes from animal studies that showed effects only at very high doses (Role of nicotinamide in DNA damage, mutagenesis, and DNA repair, 2010) and from industry safety reviews that recommend limits on concentration and product types (Cosmetic Ingredient Review). Also note some product-verification programs require extra documentation before allowing niacinamide in certified baby products.
