Abstract: 【Abstract】 Vitiligo is a chronic skin disease with a prolonged course and slow repigmentation, and ultraviolet phototherapy is widely recommended as a first-line treatment in Chinese and international guidelines. However, hospital-based phototherapy is limited by frequent visits and poor adherence, highlighting the growing need for home phototherapy. This article interprets the Specifications for the Management of Vitiligo Patients Undergoing Home Phototherapy. Developed by a multidisciplinary expert panel and effectively aligned with current national industry standards and group standards, the specifications adopt a physician-led, patient-centered core principle and establish a full-cycle management framework encompassing assessment and screening, dose management, efficacy monitoring, and follow-up. Its key contents include definitions of indications and contraindications based on disease staging, individualized starting dose protocols determined according to lesion sites and wavelengths with erythema reaction-guided dynamic adjustment strategies, differentiated management for special populations and sensitive anatomical sites, plateau identification and intermittent therapy regimens, combination therapy principles, and gradual tapering maintenance strategies following repigmentation. The specifications fill a gap in Chinese standards for home phototherapy in vitiligo, and provide a basis for its standardized implementation.
