Everything You Need to Know

Does a magnesium bath actually work?

There isn’t strong evidence just yet that magnesium improves muscle recovery, though bathing in warm water can certainly help. That said, a recent study published in JAAD Reviews found that magnesium can potentially offer better wound healing and improve conditions like eczema, acne, and psoriasis. “We are only just beginning to understand the role of magnesium in the skin,” says Shari Lipner, M.D., a board-certified dermatologist at Weill Cornell Medicine in New York, NY and co-author of the study. “Topical magnesium may be beneficial as an anti-inflammatory and may reduce water loss through the skin.”

The Benefits of A Magnesium Bath Soak

The benefits of magnesium are plenty. Many report that magnesium soaks can help ease muscle soreness, relieve tension, and generally help relax the body. As for the skin, the advantages are even more clear. “There is some evidence showing that people with atopic dermatitis or eczema could benefit from magnesium in their baths in terms of repairing the skin barrier and reducing itch,” says Dr. Lipner.

What is the best type of magnesium to soak in?

For a hot bath, it’s hard to go wrong with magnesium chloride—which, fortunately, tends to be a common magnesium in bath soaks. “Magnesium chloride is slightly preferred over magnesium sulfate for baths because it dissolves more easily in water—and both magnesium chloride and sulfate are much preferred over magnesium oxide, which is insoluble and not helpful for the skin,” says Dr. Lipner.
