The medical term for "奶癣" is infantile eczema, an allergic skin disorder often associated with genetic factors. It may result from inheriting an allergic predisposition from parents and can be triggered by environmental and dietary factors. Infantile eczema commonly occurs on the face and head, typically presenting as red patches, papules, and other lesions accompanied by itching.
