Cetraben Emollient Cream works by providing a layer of oil on the surface of the skin to prevent water evaporating from the skin surface. Moisturisers are helpful for all dry skin conditions, particularly eczema & dermatitis, which get worse when the skin is allowed to dry out. Use regularly to help restore the skins smoothness, softness & flexibility by helping the skin retain moisture. Apply frequently to prevent the skin drying out. In conditions such as eczema, using a moisturiser regularly, even once the skin has enhanced, can help prevent flareups of this condition.
