What is the best superpotent cream for atopic eczema?

Many. Every patient responds differently...Aquaphor, jojoba oil, calendula are a few. I found one called "good on ya"...You can google it...May work. Arbonne makes some great creams. A company called si jin bao has one called schmoove that is amazing as well. Diet changes, cod liver oil, probiotics may help. Seeing a homeopath or chinese medicine practitioner can help it heal from the inside out as well.
Cream for ezcema. Cobetasol is the strongest steriod cream but has limitations on where it can be used and how long it can be used. Nonsteroidal creams such as Elidel (pimecrolimus) or Protopic can give relief as well.
