Allergic eczema occurs in infants and children who have allergies or a family history of allergies. The first stage usually occurs when the child is 2 to 6 months old, when symptoms usually appear as itchy, red blisters on the cheeks, forehead or scalp. Later, these rashes may appear on the arms or torso. Many children with the disease may have the rash disappear completely or improve by the time they are 2 to 3 years old. The second stage, most common in children between the ages of 4 and 10, is characterized by round, puckered, itchy lesions that appear on the face or torso slightly above the surface of the skin. They rarely exude fluid but are more likely to crust and the skin somehow thickens. The most common sites of rash are the elbow and popliteal fossae (the bend behind the knee) and the ankle. All types of eczema are uncomfortably itchy and the skin can be very dry. The third stage usually presents with areas of skin that are markedly raised above the body surface and are extraordinarily dry and flaky. It is more likely to occur in children around 12 years of age and may sometimes persist into young adulthood. Causes Occurs due to repeated exposure to irritants such as citrus juices, bubble baths, harsh soaps, certain foods and medications, and wool or coarse woven fabrics. Also, one of the most common irritants that cause this skin problem is the baby’s own saliva. Another type of contact dermatitis occurs when a child is exposed to an allergenic substance. When dealing with eczema, the following are important: 1. Trim nails:Cut your baby’s nails as short as possible, as this will reduce the damage caused by scratching. To prevent your baby from scratching, wrap your baby’s hands in a pair of socks or gloves while he sleeps. 2, shorten the time of bathing: long exposure to soap and water will encourage dry skin and aggravate eczema. Do not bathe your baby for more than 10 or 15 minutes, and do not let your baby soak in soapy water. 3, the use of lubricants: after the bath, while the skin still remains moist, you can use some moisturizer with little stimulation according to the baby doctor’s recommendations. But do not use emollient oil or petroleum jelly. 4, control the environment: too hot, too cold or dry air can aggravate eczema, so avoid taking your baby out in extreme environments; prevent the room from getting too hot or too cold, and use a humidifier to keep the air humid. 5, the use of cotton fabrics: sweat can aggravate eczema, so do not give your baby to wear chemical fiber, silk clothes, and do not wear too much. Also avoid using cloth items that can trigger itching and clothing with rough seams, which can aggravate symptoms. Soft cotton clothes with loose inner layers are a better choice to reduce irritation. 6.Control your diet: Under the guidance of your doctor, reduce any food that can trigger the disease or aggravate eczema. 7. Undergo medication: Eczema that recurs and heals in infancy usually has no side effects. However, if the condition persists into childhood, the infected skin can become thickened, discolored and cracked. Therefore, treatment is important – usually a steroid cream or ointment applied to the infected area, antihistamines to reduce itching, and antibiotics if it becomes a secondary infection.
