The Dead Sea has long been a place of pilgrimage for people with skin conditions such as psoriasis. The beneficial effect of the Dead Sea area in psoriasis is attributed in part to the Dead Sea water, which has a high content of minerals. The Dead Sea water is rich in many minerals such as magnesium, sodium, calcium, potassium, chloride and bromide etc. While other seas contain these minerals, they do not have the same high concentrations as Dead Sea water.
Studies show that the Dead Sea water has moisturising properties, especially because of the high concentration of magnesium which helps the skin retain water1.
Furthermore, a study showed that treatment with Dead Sea salt reduced water loss from the outer layers of the skin significantly after 5 and 6 weeks of treatment in patients with atopic dry skin. The study also demonstrated that bathing in the salt solution was well tolerated, improved skin barrier function, enhanced stratum corneum hydration, and reduced skin roughness and inflammation2.
The concentration of an ingredient is important for its efficacy, and therefore products containing the same ingredient may not necessarily have the same effect as in the studies mentioned above.
