Pediatric eczema is usually caused by several factors. First, genetic factors are serious; second, it is due to immune function. Children with weaker immune systems are particularly prone to eczema; third, it is due to environmental conditions, specifically the humidity of the environment. For example, the area around a child's diaper or the indoor air might be humid, and these conditions can lead to the development of eczema in children. Typically, due to weaker immunity in children, once they contract eczema, it tends to recur and persist. Therefore, in addition to symptomatic treatment with eczema creams or traditional Chinese medicine washes, it is best to avoid using hormonal medications. At the same time, it is important to keep the skin of the affected area dry and avoid damp conditions as much as possible to prevent recurrence.
