Q: Do sea water and Dead Sea salt help with eczema?

Short answer: Sometimes yes, but not for everyone. The only way to know for sure is to try it yourself.

Some data suggests that sea water reduces eczema symptoms, but high-quality research is scarce. In 2005, scientists concluded that Dead Sea salt water strengthens the skin’s barrier function (compared to regular tap water, which does nothing). And in 2010, it was found that bathing in Dead Sea salt water combined with ultraviolet therapy is more effective than UV therapy alone.

The National Eczema Association notes that the effect of salty water on the skin can vary: for some, it’s soothing, while for others, it’s irritating. Also, it’s important to consider that when we travel to the sea, we’re exposed to a different climate – which can also affect the condition of our skin.

Sea Water Acts as an Antiseptic

Unlike river water, sea water contains more minerals, including sodium, chloride, sulfate, magnesium, and calcium. Thanks to magnesium, salty water improves the skin’s barrier function – affecting moisture retention. Additionally, sea water acts as a mild antiseptic: it helps heal small cuts and scrapes, and prevents the risk of secondary infection.

But Salty Water Doesn’t Help Everyone

Unfortunately, the only way to find out how salty water will affect your skin is to take a dip in the sea or use bath salts. You don’t need to swim for long – 10-15 minutes is enough. The main thing is to rinse off the salty water and apply moisturizer within three minutes after bathing.
