Benefits of taking a Salt Bath. On a purely visual level-Espom salt can greatly improve the appearance of skin. Taking a warm bath opens the pores, allowing the minerals in the bath to thoroughly cleanse the skin. Bathing in a solution of warm water and bath salts will work to draw out impurities, pollution, oil and dirt from the skin. Bath salts can even be an effective anti aging tool! Regular salt baths can decrease the appearance of fine lines by plumping the skin and balancing moisture.
