Balneum Medicinal Bath Oil is a bath additive used for the treatment of dry skin disorders such as Eczema and Dermatitis. Balneum relieves symptoms associated with dry skin whilst also cleansing, and helping to protect against further drying. It contains Soya Oil, which is an emollient (moisturiser) which soothes and softens dry skin by helping to replace lost oils. The oil forms tiny droplets in the water which leave a thin film on your skin. This film helps to stop your skin drying out and so makes it soft.
