The Dead Sea is a multi-tasker when it comes to beauty benefits. The water's incredible salt content (33%) is packed with minerals and is said to slough off dead skin and even relieve arthritis and psoriasis. Pair this with the nutrient-rich mud that lines the shores and you have a potent recipe for glowing skin. After emerging from the buoyant salt water, bathers often slather themselves with mud, wait for it to dry, then rinse, and repeat. Don't forget to pack your favorite T'zikal products.
