Can you suggest any remedies or treatment for atopic dermatitis that you know to be effective?

Moisturizer/steroid: If you look at eczema as a problem with inflammation and dryness, you define what you are treating more easily. Whether it's mild or severe, you should always use topical moisturizers (eucerin, aveeno, (oatmeal) even vaseline). Topical steroids will take care of the inflammation. The severity of the rash generally determines how strong it needs to be.
