Oilatum Bath Formula. Bath emollients are formulated to work with water to rehydrate and moisturise the skin. The water penetrates the skin and is then sealed in by the emollient, which creates a protective barrier. A bath emollient is convenient to use, and is the ideal choice for all-over dry skin treatment. OILATUM disperses in the bath water (unlike ordinary bath oils which can form a film on the surface) to give you an inviting, milky bath. It rehydrates the skin, helps protect against further drying, and soothes irritation. It also cleanses the skin, so you do not need to use soap. OILATUM Bath Formula is also suitable for eczema.
