Can niacinamide be used during breastfeeding?
Generally, niacinamide is not recommended during breastfeeding. The specific analysis is as follows:
The safety of using niacinamide during lactation has not yet been fully established. Although niacinamide is commonly found in cosmetics and skincare products—primarily used for skin whitening, anti-aging, and similar benefits—it may be absorbed through the skin into the bloodstream. Since a breastfeeding mother's physical condition directly affects the quality of breast milk and consequently the health of her baby, extra caution should be taken with any substance that might enter the body. Niacinamide may also cause adverse reactions such as redness, itching, or stinging of the skin. If a nursing mother experiences these side effects after using niacinamide, it could affect her physical well-being and emotional state, indirectly impacting her ability to care for her baby. Moreover, if a mother experiences severe reactions such as an allergic reaction, she may require medication, which could further increase risks to the infant.
To ensure the health and safety of the baby, breastfeeding mothers are advised to avoid using products containing niacinamide. If skincare is needed, consider choosing products with relatively safe and gentle ingredients, and consult a doctor or other healthcare professional before use.
