What is the main difference between Epsom Salt and Dead Sea Salt?
Epsom salt is composed of pure Magnesium Sulfate. It is a single-ingredient mineral salt ideal for your classic bath relaxation. Dead Sea salt is a complex ocean mineral salt containing natural minerals, including high concentrations of magnesium chloride, potassium chloride, and calcium chloride, that are known to alter water density to condition and hydrate dry skin barriers.
Why is ingredient purity important in bath soaks?
High-purity minerals—such as USP Grade Magnesium Sulfate—ensure that your bathwater is completely free of anti-caking agents, heavy metals, synthetic fillers, or artificial dyes. Pure minerals dissolve cleanly, protecting both sensitive skin barriers and commercial bath/float filtration systems.
