Eczema, or atopic dermatitis, is a condition in which the skin becomes inflamed, according to the American Academy of Dermatology. In psoriasis, silvery plaques build up on the skin because the skin cells grow too quickly and do not slough off the way they should.
Eczema is a very common skin disorder in young children, and many children get it before they are a year old, claims the American Academy of Dermatology. The disease presents as itchy, warm, red patches on the child's scalp, cheeks and face. The itching is sometimes so intense that the child causes a skin infection by scratching herself.
One treatment for eczema is a bleach bath. In this therapy, 1/2 cup of 6 percent strength bleach is added to a full bathtub. For a baby still using a baby's bathtub, a teaspoon of bleach is added for every gallon of water. The child soaks for about five to 10 minutes, and then her skin is patted dry, and eczema medication and moisturizer are applied.
In psoriasis, the immune system sends faulty signals to the skin cells, states the American Academy of Dermatology. There are several kinds of psoriasis, and there are some patients who contract more than one kind. As of 2015, psoriasis has no cure.
