Classifying Vitiligo Severity Beyond Body Surface Area
ByRyan Haumschild, PharmD, MBA,David Rosmarin, MD,Seemal R. Desai, MD, FAAD,Jason Fehr, MA,Karan Lal, DO, MS, FAAD A recent JAMA Dermatology analysis refines mild-moderate-severe cutoffs for vitiligo, but Dr. Desai and Dr. Lal argue that psychosocial burden, anatomic site, and cultural context can make even limited disease profoundly severe for patients.

Payer Barriers and Anatomic Urgency in Vitiligo Treatment
ByRyan Haumschild, PharmD, MBA,David Rosmarin, MD,Seemal R. Desai, MD, FAAD,Jason Fehr, MA,Karan Lal, DO, MS, FAAD Halting progression early is more achievable than reversing it. Dr. Rosmarin details how oral steroids control active disease while payer barriers persist for later-line options, and Jason explains how benefit design and step therapy shape access.

Why Body Surface Area Alone Doesn't Capture Vitiligo Severity
ByRyan Haumschild, PharmD, MBA,David Rosmarin, MD,Seemal R. Desai, MD, FAAD,Jason Fehr, MA,Karan Lal, DO, MS, FAAD Body surface area offers a simple starting point for gauging vitiligo severity, but the panel argues that phenotype markers, anatomic location, and disease activity carry more weight in shaping treatment urgency than surface area alone.

Vitiligo Types, Progression, and What Patients Fear Most
ByRyan Haumschild, PharmD, MBA,David Rosmarin, MD,Seemal R. Desai, MD, FAAD,Jason Fehr, MA,Karan Lal, DO, MS, FAAD Vitiligo's clinical course splits into segmental and non-segmental presentations, each carrying a distinct prognosis. Dr. Rosmarin explains how disease activity, not just extent, determines whether a patient needs urgent intervention or watchful monitoring.
