EpiCeram
"I think some folks may be confused about what this is supposed to do and the days it takes to do it. It restores your skin's own barrier to help heal and prevent a "break" = eczema and atopic dermatitis. You put it on first, then your prescription a few minutes later, if you need one. You use it for at least 2-4 weeks to strengthen your own skin from the damaged outer layer so it stops and prevents an active break(out). Almost nothing worked on me, including "shielding lotions." From their  instructions: Should EpiCeram® be prescribed along with corticosteroids or a topical immunomodulator, it is recommended to apply EpiCeram® just a few minutes before applying steroids or topical immunomodulator to allow proper penetration."
