Around one month after birth, small red rashes and red spots may appear on the cheeks, scalp, extremities, or even on the whole body. In some cases, small blisters, oozing, yellowish-white scales and scabs can be seen. If improper care will also cause local vesicles and even secondary infections, this is often referred to as “infant eczema”. The reason for the onset of infant eczema] 1, infant internal physiological factors: infant intestinal wall is thin, its permeability is high, some food particles can easily enter the blood directly through the intestinal wall, the formation of the corresponding antibodies, once this type of food re-enter the body, antigen and antibody reaction will cause allergies. 2, external factors: mechanical friction (such as saliva and spilled milk for a long time to stimulate the local skin), or the use of strong alkaline detergents, and the consumption of too high nutrition. 3.Family genetic: there is a family history of allergy. Encounter with sunlight, ultraviolet light, cold, heat and humidity, contact with chemical fiber clothing, food and the use of improper baby skin care products. The following three types of eczema are mostly seen clinically] 1. seborrheic type; 2. exudative type; 3. dry type; The above three types of eczema can exist alone or at the same time. The skin of infants has a thin stratum corneum, a rich capillary network, and a high water content in the epidermis of the skin, which is prone to metamorphosis because of the characteristics of the skin structure. 1. It is not easy to use strong alkaline detergents in life. Pay attention to moisturizing, use warm water to wash after the whole body can be applied to the baby moisturizing oil or moisturizing cream. 2, pay attention to a reasonable diet, timely addition of complementary foods, has added complementary foods to reduce the intake of animal fat and sugar, increase protein, give the right amount of fruits and vegetables. 3, try to avoid contact with artificial fiber, silk and other chemical fiber clothing. The temperature in the house is not easy to be too high. 4, for chronic children can use hormone-containing ointment, or oral anti-allergy drugs. Hormone creams should not be used for a long time (preferably no more than 2 weeks for the face) to prevent dependence or adverse reactions, such as skin atrophy. Generally strong or most potent hormonal medications are not recommended for the face, and the use of hormones is contraindicated in the case of co-infected eczema. Therefore, infants should be seen promptly at a regular hospital when they are ill. It is important to take the advice of a physician in the use of medication and strive to use it appropriately.
