Signs and related symptoms of eczema are different in infants, children, and adults. Infants Eczema can appear when a child is 2 to 3 months old. It appears as a rash, turning the skin scaly, dry, and itchy. While it can appear on any part of the body, it often forms on the face, scalp, and cheeks. Itching can come and go, and areas can bubble up to ooze and weep fluid. Parents mistakenly believe that diaper areas are vulnerable to eczema. However, it rarely appears there since that area of the skin is too moist for it. Children Eczema will begin to appear on children after they turn two up until they reach puberty. A rash will develop on the knees, neck, elbows, ankles, wrists, or the crease between their legs and buttock. Their skin will often appear scaly, itchy, and can either be lighter or darker. In some cases, skin can thicken and turn leathery. Adults It is very rare for adults to develop eczema and they often have milder symptoms. It usually appears in the crease of the elbows or the nape of the neck. It isn’t uncommon for it to cover the entire body. It can be especially bad around the eyes and cause dehydrated and scaly skin. Skin infections are also more likely.
