Short answer: The Dead Sea, bordered by Israel, the West Bank, and Jordan, is the lowest point on Earth (about 439.78 meters, or 1,443 feet, below sea level) and one of the saltiest bodies of water anywhere, roughly 34% salinity, about 9.6 times saltier than the ocean, according to Wikipedia. Its water is unusually rich in magnesium, calcium, potassium, and bromide. The strongest evidence for its skincare reputation comes from a controlled 2005 dermatology study: bathing dry, atopic skin in a magnesium-rich Dead Sea salt solution improved skin-barrier function, boosted hydration, and reduced roughness and redness (Proksch et al., 2005). So the accurate headline for 2026 is hydration and barrier support, and a good routine pairs Dead Sea minerals with a vitamin C serum for antioxidant brightness.
What makes Dead Sea minerals different
The Dead Sea is a hypersaline lake, and its chemistry is genuinely distinct from ordinary seawater. By share of dissolved mineral salts, it is dominated by magnesium chloride (about 50.8%), followed by sodium chloride (30.4%), calcium chloride (14.4%), and potassium chloride (4.4%), and it holds the highest bromide concentration of any water on Earth (Wikipedia). That is why "magnesium-rich" is the precise description, rather than a vague "mineral-rich" claim. Sitting about 439.78 meters below sea level, the shore also has an unusual UV profile, and that filtered sunlight is the basis for photoclimatherapy used on skin conditions such as psoriasis (Wikipedia).
What the science actually supports
The most citable result is still the 2005 study by Proksch and colleagues in the International Journal of Dermatology. Researchers had people with dry, atopic skin soak one forearm in a 5% magnesium-rich Dead Sea salt solution and the other in tap water. The salt-treated skin showed significantly better barrier function, higher hydration, and less roughness and redness, with the benefit credited to magnesium (Proksch et al., 2005). Magnesium salts bind water and play a role in how skin cells grow and repair the barrier, which fits the observed calming, hydrating effect.
It is worth keeping the claims measured beyond that one result. A Cochrane review found only low-quality evidence that salt bathing combined with UVB light helps psoriasis, and reviewers note that many balneotherapy studies have methodological weaknesses (Wikipedia). Dead Sea mud is best understood as a gentle cleanser and mild exfoliant, not a "detox." And if your real goal is a brighter, more radiant glow, the best-evidenced active is topical vitamin C, an antioxidant that neutralizes free radicals and serves as an essential cofactor in collagen synthesis (Wikipedia). The smart move is to let Dead Sea minerals handle hydration and barrier support, and add a vitamin C serum for brightness.
Made in Israel, sourced from the Dead Sea
The category has a clear Israeli anchor. AHAVA (AHAVA Dead Sea Laboratories) was founded in 1988, starting as a single stand selling Dead Sea body scrub to tourists, and it is headquartered in Lod. As of 2010, it was the only cosmetics company licensed by the Israeli government to mine raw materials at the Dead Sea, extracting minerals such as calcium, magnesium, and potassium from its water (Wikipedia). A couple of details are worth knowing so you can shop with clear eyes: Israel has imported some raw materials for Dead Sea mud cosmetics from Jordan since 1994, and AHAVA came under controlling ownership by China's Fosun International in 2015 (Wikipedia). The Dead Sea minerals themselves, though, remain an Israeli natural resource, and buying from Israeli makers keeps that story intact.
