The warm desert sun evaporates the Dead Sea water, so the salts and minerals get absorbed into the mud at the bottom of the sea. This makes the natural black mud a mixture of Dead Sea salts and minerals, rich in natural tar, and silicon compounds. Dead Sea Mud is very useful for cleansing and softening skin while stimulating blood circulation to keep your skin looking younger and healthier. In addition, Dead Sea mud pulls out all toxins and impurities from the skin, resulting in a wonderful glow. Dead Sea Mud also firms and tightens the skin, making it an exceptional anti-aging therapy.
