Appearance, history, and selective tests & Retaining moisture and reducing irritation

Appearance, history, and selective tests

Diagnosis primarily uses skin appearance and personal and family history. Biopsy can help confirm a diagnosis or investigate other causes. Allergy tests may be useful with difficult-to-treat disease, other allergic symptoms, or a specific exposure-related eruption. Cultures can investigate infection. Tests therefore address particular questions, not a rule that all eczema is an allergy or that every person needs the same testing. Moisturizers help retain water, especially when applied while skin is still damp.

Retaining moisture and reducing irritation

Moisturizers help retain water, especially when applied while skin is still damp. Gentle cleansers and brief cool bathing are preferred to harsh rubbing or prolonged hot bathing. Fragrances and other irritating ingredients can worsen symptoms. Prescribed topical corticosteroids or other topical treatments may control inflammation; harder-to-control disease may need additional therapy. Infected skin may need antibiotics. Avoiding irritants and reducing scratching support the care plan.
