For decades, conversations about topical therapy have centered on familiar questions: How well does it work? How long can it be used? Where can it be applied safely? As new nonsteroidal therapies continue to expand the treatment landscape, another question has emerged: does understanding a therapy's mechanism change the way we think about inflammatory skin disease? 

The aryl hydrocarbon receptor (AhR) pathway has introduced a distinct way of approaching immune regulation, skin barrier function, and oxidative stress. As clinicians gain more experience with AhR agonism in psoriasis and atopic dermatitis, understanding the biology behind the pathway offers more than scientific context—it helps explain the clinical effects observed in practice and informs how these therapies fit into long-term disease management. 

Drawing on insights from an expert consensus panel, this educational experience brings together leading clinicians to explore the science, practical application, and evolving role of AhR agonism in inflammatory skin disease. Through discussions, case-based perspectives, and conversations that connect mechanism to patient care, the series examines what makes this therapeutic pathway different, and why that difference matters in everyday practice.
