Infant eczema, also known as atopic dermatitis, is a chronic recurrent inflammatory skin condition that generally occurs during infancy. The main causes are likely related to genetic factors, environment, immunity, biological factors, and more. The rash typically features chronic recurrent dermatitis in areas such as the face, neck, antecubital fossa, and popliteal fossa. Occasionally, the eczema may also involve the chest, abdomen, back, and limbs, although this is less common.
