Eczema stems from a weaker skin barrier and an overactive immune response, so daily barrier care is the real foundation.

Key takeaways

• Eczema stems from a genetically weaker skin barrier combined with an overactive, allergy-prone immune response.
• Daily moisturising with a thick, fragrance-free emollient is the single most important management step.
• Topical corticosteroids and calcineurin inhibitors treat active flares when matched correctly to severity and body area.
• Newer biologic and JAK inhibitor treatments have expanded options for moderate to severe, treatment-resistant cases.
