Eczema plaques can be magnets for infection. It's hard to clean the skin well enough to prevent infection without irritating/inflaming it.
I used to have severe eczema, but I grew out of it. Back then, I usually used Oil of Olay or Dove sensitive skin bar soap, but if it was really bad, I could only wash some areas with Alpha Keri Oil. I always used Keri sensitive skin lotion. They didn't have dye free laundry detergents back then so, I would run my clothes a second time without any soap.
I hope that they find out what works out well for Harmony soon. They'll get some good tips, but it's really trial and error.
I'm glad you had a great Valentine's Day dinner!
