What is the difference between baby heat rash and eczema?

Baby heat rash and eczema are two different skin conditions, with the main differences as follows: 1. Affected areas: Heat rash commonly occurs in skin folds of infants, such as the neck, armpits, and elbow creases, while eczema can appear on any part of the body, especially the face, limbs, and trunk. 2. Symptoms: Heat rash typically presents as red papules or small blisters, accompanied by itching; eczema may exhibit various forms including erythema, papules, and blisters, often with a tendency to exude, making the skin appear rough and thickened. 3. Causes: Heat rash is primarily caused by blocked sweat glands due to poor sweat excretion in hot and humid environments; eczema may be related to multiple factors such as genetics, environment, and immunity. 4. Treatment: Management of heat rash mainly involves maintaining clean and dry skin and avoiding hot, humid environments; eczema requires individualized treatment based on severity and underlying causes, such as using anti-inflammatory and antiallergic medications.
