Spotlight on skin: Shining a light on Vitiligo awareness and inclusion

World Vitiligo Day champions hope and innovation

Advertisement

World Vitiligo Day is observed every year on June 25, commemorating the passing away of Michael Jackson—who had vitiligo—on that date in 2009. The first global observance took place on June 25, 2011, initiated by Steve Hargadon and later championed by Ogo Maduewesi from Nigeria. The date was chosen in memory of Jackson and to raise awareness of the condition.

History & evolution

Prelude in India: Prior to 2011, India observed a national Vitiligo Day on May 19, established at PGIMER, Chandigarh, by Dr Savita Malhotra. India joined the global date in 2015.

First global observance (2011): Purple-themed fun day held in Lagos, Nigeria, coinciding with Michael Jackson’s memory; grassroots events spread worldwide.

World Vitiligo Day 2025 theme

“Innovation for Every Skin, Powered by AI”

This theme underscores breakthroughs in AI-driven diagnostics, personalised treatments, enhanced care access and equity for those with Vitiligo worldwide.

Understanding Vitiligo

What is Vitiligo?

Vitiligo is a chronic autoimmune disorder marked by the loss of melanocytes, resulting in depigmented white patches of skin.

Causes & risk factors

Exact cause remains unknown; however:

• Autoimmune attack on melanocytes is the primary hypothesis
• Genetic predisposition: around 36 susceptibility loci identified, including TYR
• Triggers: sunburn, emotional stress, chemical exposure, and mechanical trauma (Koebner phenomenon)
• Oxidative stress via mitochondrial dysfunction may also play a role

Symptoms

• Depigmented patches, often on face, hands, extremities; may have itching before onset
• Hair whitening, including eyelashes and eyebrows; may lead to psychological distress

Diagnosis

• Clinical observation, aided by Wood’s lamp to detect subtle pigment loss
• Rarely skin biopsy; Type: non-segmental (most common) vs segmental

Treatment & management

No definitive cure, but management strategies include:

• Topical corticosteroids/calcineurin inhibitors
• Phototherapy (narrowband UVB)
• JAK‑inhibitor cream (ruxolitinib/Opzelura) approved in US in 2022
• Skin camouflage and depigmentation for extensive cases
• Surgical options: melanocyte transplant methods show 70–85% repigmentation efficacy

Stylistic tips & vocabulary notes

• Use evocative phrases: “melanin deficit,” “chromatic dearth,” “autoimmune onslaught,” “cosmetic equity.”
• For policy insights, integrate terms like “healthcare equity,” “biomedical innovation,” “public awareness campaigns,” “social stigma.”
• Include vivid exam-specific connectors: “furthermore,” “counterintuitively,” “holistic policy framework,” etc.
