The benefits of bathing in magnesium-enriched water Magnesium has been recognised by medical professionals and consumers all over the world for its ability to alleviate a variety of ailments relating to the skin, muscles and nervous system.

A large body of mainly anecdotal evidence has shown that magnesium salts, the main mineral in the Dead Sea and naturally occurring in the human body, markedly improves skin hydration, soothes common skin conditions such as dermatitis, eczema and Psoriasis. Magnesium-enriched water also provides temporary relief from muscular inflammation and fatigue.

Research undertaken by a number of medical establishments, including Germany’s University of Kiel’s Department of Dermatology¹,  attributes the Dead Sea’s skin soothing and strengthening properties to its high magnesium salt content:

Skin roughness and redness of the skin as a marker for inflammation were significantly reduced after bathing in the salt solution. This  demonstrates that bathing in the salt solution was well tolerated, improved skin barrier function, enhanced stratum corneum hydration, and reduced skin roughness and inflammation. 

We suggest that the favorable effects of bathing in the Dead Sea salt solution are most likely related to the high magnesium content.

Magnesium salts are known to bind water, influence epidermal proliferation and differentiation, and enhance permeability barrier repair.


Improved water clarity:

Mineral Crystals are also known for its mild flocking abilities, which helps to filter out fine material such as dust and dirt. Reducing the need for additional chemicals like clarifiers and algaecides, delivering pool owners further cost savings.
