If childhood eczema is not improving, then it is crucial to actively search for the cause, rather than merely treating the symptoms. The care for childhood eczema mainly involves moisturizing and applying eczema ointment, but treating the primary cause is most important. The causes of eczema are varied, with common factors including genetics. If a child's parents have allergic rhinitis, eczema, or asthma, it suggests that the baby might have an allergic constitution, which can lead to recurrent episodes of eczema. Additionally, diet plays a role; consuming foods that are allergens can also trigger eczema flare-ups, especially foods containing proteins such as dairy products, eggs, and seafood products. Furthermore, contact with allergenic substances like animal dander and plant pollen can also induce eczema. Moreover, certain specific pathogens colonize on the surface of eczema-affected skin, leading to repeated outbreaks. These factors make the treatment of eczema less than ideal, so it is essential to understand the specific reasons behind the baby's eczema to tailor the treatment effectively.
