Aurora Sea Salt is salt produced from the evaporation of seawater, rather than by being extracted from sedimentary deposits. It is used in cooking and cosmetics. It is also called bay salt or solar salt. Sea salts that have a high magnesium content may be the best type to add to baths for those with skin issues. Getting enough sodium, regardless of the type of salt it's from, is important for hydration and blood pressure. Some research suggests it may also aid digestion and improve skin issues when added to baths. Sea Salt has a briny mineral taste and a chunky texture. Aurora Fine Sea Salt is not iodized.
