Also called wool fat, lanolin is a greasy wax that has moisturizing properties and high water-absorption capabilities. It comes from the secretion of wool-bearing animals. Considered hypoallergenic and to limit the growth of bacteria, lanolin can be used as a cream to soothe skin. Lanolin cream can be used by breastfeeding mothers, to treat chapped lips, diaper rash, dry or itchy skin, rough feet, and minor cuts and burns.
