Lanolin is used as a cream to soothe skin, as it is hypoallergenic and bacteriostatic. In this form it is used by some breastfeeding mothers on sore and cracked nipples. This grade of lanolin can also be used to treat chapped lips, diaper rash, dry skin, itchy skin, rough feet, minor cuts, minor burns and skin abrasions. Many varieties of shaving cream contain lanolin. As an ointment base, it is readily absorbed through skin, facilitating absorption of the medicinal chemicals it carries. Using cosmetic products which contain impure lanolin can cause an allergic reaction in some people.
