Do you need to wash off lanolin before breastfeeding?

Whether lanolin needs to be washed off before breastfeeding depends on the product type. Food-grade or edible-labeled lanolin does not require washing; however, regular skincare-grade lanolin or products containing fragrances and preservatives should be thoroughly cleaned off before nursing. The details are as follows:

Food-grade lanolin has high purity, meets safety standards, and contains no harmful additives. Even if small amounts are accidentally ingested by the baby, it will not cause harm. These products are specifically designed for breastfeeding mothers. After application, they help moisturize nipples and relieve dryness or cracking. Babies can nurse directly without the need for additional cleaning.

Regular skincare-grade lanolin may contain impurities, fragrances, preservatives, and other ingredients that are generally safe for adults but could cause discomfort in infants, whose digestive and immune systems are not yet fully developed. Additionally, after application, the nipple surface may collect dust or bacteria, increasing the risk of infection for the baby if nursing occurs without prior cleansing.

When using lanolin during breastfeeding, always prioritize food-grade products from reputable brands, and apply in moderation to avoid excessive buildup. If using regular skincare-grade lanolin, gently wash the nipple and surrounding skin with warm water before nursing, then pat dry before feeding.
