What are the best diet and skincare products for eczema(skin disorder)?

None: Eczema may be caused by many reasons. If you use allergic contact eczema as example: diet would not help; skincare product might have been the "cause"!

Many: Avoid things that make you break out, soaps & wetness. Wash your hands only when necessary. Wear gloves when needed. Wear clothes made of cotton. Bathe only with a small amount of mild unscented soap, such as dove. Keep the water temperature cool or warm, not hot! use the medicine your doctor gave you. Use a plain moisturizer daily. Avoid scratching or rubbing the itchy area. Manage stress.

Food elim diet: A food elimination diet removes the top 10 food allergens from your diet. Since the skin is a direct reflection of the gut and immune system, being on this diet calms the immune system reaction and decreases the symptoms. Topically, i recommend eucerin cream.
