Could cutting salt soothe your skin? new study investigates
NCT ID NCT07487831
First seen Jun 27, 2026 · Last updated Sep 10, 2026 · Updated 2 times
Summary
This study looks at whether changing how much salt you eat can affect skin sodium levels and the severity of eczema or psoriasis. Fifty adults will follow a low-salt diet and take either sodium tablets or a placebo for several weeks. The goal is to see if this approach is practical and to gather early data on the link between salt and skin inflammation.
