Emulsifying ointment is a mixture of paraffin oils. It is a greasy moisturiser that provides a layer of oil on the surface of the skin to prevent water evaporating from the skin surface. Moisturisers such as emulsifying ointment are helpful for very dry skin conditions, particularly eczema & dermatitis, which get worse when the skin is allowed to dry out. Used regularly they help restore the skin's smoothness, softness & flexibility by helping the skin retain moisture. They should be applied frequently to prevent the skin drying out. Emulsifying ointment can also be used in place of soap when washing to prevent drying the skin. In conditions such as eczema, using a moisturiser regularly, even once the skin has enhanced, can help prevent flare-ups of this condition.
