Liquid Paraffin + White Soft Paraffin is a combination of liquid paraffin and white soft paraffin. Liquid paraffin is an emollient (substance that soothes or softens the skin). It prevents water loss from the outer layer of skin. This relieves dryness and leaves the skin hydrated and soft. White soft paraffin provides a layer of oil on the outer layer of the skin to prevent water evaporating from the skin surface.
