Summary Vitiligo has a substantial negative impact on quality of life in affected patients, especially those with the involvement of the face. However, the current system can barely distinguish between specific patterns of facial involvement except for the segmental type when focusing only on facial lesions. We classified facial vitiligo into three distinct subtypes using cluster analysis based on facial topography ( n = 473): centrofacial vitiligo (72.9%), panfacial vitiligo (18.0%), and hairline vitiligo (9.1%). Centrofacial vitiligo was the most common type and is thought to comprise the typical facial involvement of generalized vitiligo. Panfacial vitiligo was a distinct subtype with onset in old age and less involvement of other body parts. Hairline vitiligo was another distinct subtype with onset in old age and a poor response to conventional phototherapy. A relevant classification system could help us to explore the causes, anticipate the prognosis, and manage the condition in patients with vitiligo.
