Your baby has sensitive skin because it has fewer glands to secrete oil, therefore it is dryer than adult skin. Daily bathing and wiping with moist towelettes actually dry out the natural protection your baby's skin needs. The result is your baby can't produce enough oils to protect its skin, making your baby susceptible to diaper rash and infant eczema. Formula II contains mineral oil which helps to moisturize your baby's skin. It is also formulated with three waxes which hold moisture in and provide a protective barrier which is very effective in helping to heal Infant Eczema. Benefits of Formula II: Contains mineral oil which replaces the oil that your baby's skin needs Formulated with three waxes which help hold in your baby's natural moisture Acts as a barrier to help protect your baby's skin Usage: For Diaper Rash, apply after each diaper change.
