Vitiligo is a common skin disorder, characterized by de-pigmented milky white patches on the skin. It is an acquired disorder, which leads to a chronic and progressive loss of melanocytes from the epidermis and follicular reservoir.
The term Vitiligo was used for first time by a Roman Physician Celsus in the 2nd century AD. The Atharvaveda mentioned leukoderma as a variety of Leprosy (Shwetakushtha) along with a prescription of several herbal remedies. This book dates back to 1400 B.C.
While the current incidence of Vitiligo is not accurate, it is conservatively estimated that about 0.5-2% of the global population is afflicted by it. That means anywhere between 35 and 140 million people. Moreover, Vitiligo affects both genders and all races equally. It is also assumed that prevalence is similar throughout the world and in all ethnic groups. However, there is less data to support the frequency of the disease.
