Short answer: Dead Sea skincare products from Israel rest on a genuine foundation. The Dead Sea, on Israel's eastern border, is the lowest point on Earth's surface and among the most mineral-rich bodies of water anywhere, unusually high in magnesium, calcium, potassium, and bromide. The strongest clinical evidence comes from a 2005 dermatology study in which bathing dry, sensitive skin in a magnesium-rich Dead Sea salt solution improved the skin barrier, raised hydration, and reduced roughness and redness (Proksch et al., Int J Dermatol 2005). The minerals genuinely support the skin barrier, though it helps to separate marketing language from what studies actually show.
The lowest point on Earth, exceptionally mineral-rich water
The Dead Sea sits about 439.78 meters below sea level (as of 2025), the lowest land elevation anywhere on the planet, bordered by Israel to the southwest and west (the West Bank) and Jordan to the east (Wikipedia). Its water is roughly 34.2 percent salt, nearly ten times saltier than the ocean, which is why you float so effortlessly on its surface and why it counts as one of the world's saltiest bodies of water.
What makes it special for skin is not the saltiness alone but the mineral profile, which is very different from ordinary sea salt. By weight the dissolved salts are about 50.8 percent magnesium chloride, 14.4 percent calcium chloride, and 4.4 percent potassium chloride, with the highest bromide concentration of any water on Earth and unusually low sulfate (Wikipedia). Magnesium is the standout, and it is the mineral cosmetic makers point to most. That bromide dominance and the magnesium-heavy makeup are what set Dead Sea salt apart from the table salt or ordinary sea salt found in most bath products. It is a fundamentally different mineral cocktail, formed over millennia as this landlocked sea evaporated and concentrated.
What the science actually shows
The landmark study is Proksch et al., published in the International Journal of Dermatology in February 2005. Volunteers with dry, atopic skin bathed one forearm in a 5 percent Dead Sea salt solution and the other in plain tap water. The salt-treated skin showed improved barrier function, higher stratum corneum hydration, and reduced roughness and redness, and the authors credited magnesium's ability to bind water and support barrier repair (Proksch et al., Int J Dermatol 2005). Magnesium is naturally hygroscopic, meaning it draws and holds water, and that water-binding property is the mechanism the study points to for the improved hydration and calmer, less inflamed skin the volunteers experienced.
The Dead Sea region has also served as a psoriasis-treatment destination for decades, a practice known as climatotherapy. Because it sits at the lowest point on Earth, an extra layer of atmosphere filters some ultraviolet radiation, letting patients take longer, safer sun exposure alongside mineral bathing (Wikipedia).
A fair caveat keeps this grounded: broad reviews of balneotherapy (mineral-water and mud bathing) note that many studies have methodological weaknesses, and the strongest skin evidence is for salt bathing combined with UVB light rather than mineral soaking alone (Wikipedia, Balneotherapy). So the measured position is this: well-run studies support hydration, barrier support, and soothing, while sweeping healing claims go beyond the evidence.
An ancient resource, a modern Israeli industry
People have valued these waters for a very long time. The Dead Sea was one of the world's first health resorts, drawing visitors from around the Mediterranean for thousands of years, and its shoreline even supplied asphalt used in Egyptian mummification (Wikipedia). Today that heritage anchors a real industry: Israeli companies generate around US$3 billion annually from Dead Sea minerals, chiefly potash and bromine, and several supply Dead Sea salts as raw material for body and skin care (Wikipedia).
Bringing the Dead Sea into your routine
You do not need a plane ticket to Israel to put these minerals to work. Dead Sea minerals reach your bathroom in several familiar forms: coarse bath salts you dissolve in warm water, spreadable mineral mud masks, lightweight face serums, and richer night creams and moisturizers. If you want to try the magnesium-rich salts, muds, and mineral creams for yourself, our Dead Sea collection gathers authentic body care, face serums, and mineral mud drawn from the same waters described above. Keep your expectations aligned with the evidence: reach for these products for hydration, barrier support, and soothing dry or rough skin, rather than as a cure, and you will be using them exactly the way the research supports.
