Eli5: As somebody with eczema, why can’t dry skin just be rehydrated by water, why does water make it worse, especially hot water I’ve been told

448 viewsBiologyOther

I get really bad eczema on my hands, and the doctors tell me I wash my hands too much, never knew that was a thing but I work in a restaurant so don’t really have a choice. But I just don’t understand why we need lotion or prescribed ointment, why can’t I just skin my hand in a tub of water for an hour and bam hydrated.

Because water evaporates. Your skin is supposed to be a barrier to water going in or out. Water isn’t supposed to go past the top layer of skin. Your body produces oil to help it keep the inside water in, and the outside out. Soap gets rid of it, so now your skin is dry.
