Niacinamide is generally considered safe for use during pregnancy and breastfeeding when applied topically in skincare products. However, it is always best to:

• Consult your healthcare provider before starting any new skincare ingredient during pregnancy or while breastfeeding.
• Use products with niacinamide in recommended amounts, avoiding high-dose supplements unless prescribed.
• Monitor for any skin irritation or allergic reactions.

Topical niacinamide is known for its benefits in improving skin barrier function and reducing inflammation, and it does not typically pose risks to the baby. Oral niacinamide supplements should be used cautiously and only under medical advice.

If you have any concerns or specific health conditions, discussing them with your doctor or dermatologist will ensure the safest approach for you and your baby.
