Before 2021, vitiligo was not clearly included in the facial disability criteria.
At that time, the facial disability criteria included 'facial scars, pigmentation, hair loss, tissue hypertrophy or depression,' but administrative agencies interpreted 'pigmentation' primarily as hyperpigmentation, where the skin color darkens.
In contrast, vitiligo is a disease in which melanocytes are lost, causing the skin to turn white, so it was often excluded from those criteria.
As a result, even people with extensive vitiligo on the face who experienced significant difficulties in daily life and social activities were unable to register as disabled.
