Lansinoh HPA® Lanolin is an ultra purified grade of lanolin, refined using a unique process to make it the world's safest, purest lanolin. Lansinoh HPA® Lanolin has been specially developed to help soothe and protect sore, cracked nipples in breastfeeding mothers. Sore nipples can often be a result of uncomfortable positioning of your baby at the breast. It is therefore important to address the cause (with the help of a health professional if necessary) - and in the meantime Lansinoh HPA® Lanolin can help to soothe and protect your nipples. Lansinoh HPA® Lanolin is the safest, purest nipple cream and completely hypoallergenic. Lansinoh HPA® Lanolin is the only lanolin product to have received the British Allergy Foundation Seal of Approval.
