Clearing the (Skin) Stigma: The Truth About Vitiligo
Vitiligo is a chronic skin condition in which patches of skin lose their pigmentation, resulting in white or light-coloured patches. It affects approximately 1–2% of the global population — including an estimated 50 million people in India. Despite its prevalence, vitiligo carries significant social stigma, particularly in South Asia, where it is often misunderstood and associated with myths.
What Causes Vitiligo?
Vitiligo occurs when melanocytes — the cells responsible for producing skin pigment (melanin) — are destroyed or stop functioning. The exact cause is not fully understood, but it is believed to involve a combination of:
Autoimmune factors: The immune system mistakenly attacks melanocytes
Genetic predisposition: Vitiligo runs in families; multiple genes have been associated with increased risk, including PTPN22, CTLA4, and HLA region variants
Environmental triggers: Sunburn, stress, and chemical exposure can trigger or worsen vitiligo in genetically susceptible individuals
Types of Vitiligo
Non-segmental vitiligo (most common) — symmetrical patches on both sides of the body; tends to spread over time
Segmental vitiligo — affects only one side or segment of the body; often stable after initial spread
Universal vitiligo — affects most of the body surface
Breaking the Stigma
Vitiligo is not contagious. It is not caused by diet, karma, or any of the myths that persist in Indian society. It does not affect life expectancy. Many people with vitiligo live full, healthy lives — and the condition is increasingly celebrated as part of human diversity. Awareness, education, and empathy are the most powerful tools we have against stigma.
Management Options
While there is no cure, treatments can help restore pigmentation or slow the spread: topical corticosteroids, calcineurin inhibitors, phototherapy (NB-UVB), and in some cases, surgical options. Early treatment tends to be more effective.
