The lanolin alcohol used in Eucerin is a highly refined emollient that has been proven to effectively protect and moisturize the skin. It is not related to other alcohols that are drying and can irritate the skin. The Eucerin brand has been recognized by dermatologists and pediatricians for its excellent safety and effectiveness for more than 50 years. Many individuals who are sensitive to the lanolin found in other products, can safely use Eucerin without a reaction since the lanolin in Eucerin must pass high purity and quality standards. However, if a reaction occurs, please discontinue use immediately. Back to top .
