Lansinoh Lanolin Lansinoh's HPA Lanolin has been developed for breastfeeding mothers to soothe and protect sore and cracked nipples. Sore nipples are very common during breastfeeding and can often be a result of the uncomfortable positioning of your baby at the breast. Lansinoh HPA Lanolin is composed of an ultra-purified grade of lanolin which has been refined using a unique process, making it safe for both mum and baby, with no need to remove before breastfeeding. 100 per cent natural without any preservatives or additives, it is naturally hypoallergenic. It is also the only lanolin product to have received the British Allergy Foundation Seal of Approval.
