Professor Steven Thng Tien Guan, deputy director of National Skin Centre (NSC), has these insights on vitiligo:
Cause: Vitiligo is an autoimmune disease – white blood cells attack and destroy the skin’s melanocytes (pigment-producing cells), leading to white patches on the skin. Genetics may predispose individuals to vitiligo. It can also be triggered by injury to the skin, stress and sunburn.
Prevalence: In Asia, around seven in a 1,000 people have vitiligo.
