Atopic dermatitis (AD) is a chronic disease driven by persistent underlying inflammation even in nonlesional or normal looking skin2–4

An imbalanced immune system, together with epidermal abnormalities, drive Type 2 inflammation2–4

IL-4 and IL-13 are key Th2 cytokines involved in AD2–4

These cytokines modulate the immune response, drive persistent inflammation and contribute to worsening barrier dysfunction2–4
